Tips for buying a New or Used Heavy Equipment

Buying used equipment can save even more money than buying a NEW us but even so used heavy equipment may still require expenses / repairs that if not careful could spend significant time and cost could even equal the difference in price if we buy heavy equipment new, but now many people who anticipate buying a new machine with low price, namely the heavy equipment from china.

Price of used equipment could be 50% cheaper than new but if the use of heavy equipment is not monitored, then the cost to repair will quickly swell and this obviously is not profitable. Therefore, for users who intend to purchase used equipment more or less technically should know about maintenance and maintenance equipment.

LOAN / LEASING
Because of the high prices for equipment, almost all consumers by way of leasing or buying credits. Many companies buy heavy equipment to the dealers who usually provide a means of finance or leasing. And the dealer is set up an agreement with the Bank or Leasing Company. Generally, companies that want to buy on credit will definitely compare the rates or terms that he got with leasing companies or other banks.

Heavy Equipment For Construction Projects

Heavy equipment known in the science of Civil Engineering is a tool used to assist humans in doing building a structure. Heavy equipment is an important factor in the project, especially construction projects with a large scale.

The purpose of the use of heavy equipment is to facilitate people in doing his job so that expected results can be achieved more easily in a relatively short time. Heavy equipment commonly used in kostruksi projects include:
- Dozers,
- Digging equipment (excavator) such as backhoe, front shovel, clamshell;
- Transport equipment such as loaders, trucks and conveyor belts;
- The ground like a roller compactors and compactor, and others.

Heavy equipment in construction projects has an important role. Therefore, the understanding of the types of heavy equipment is needed, especially at the planning stage because of heavy equipment must be selected in accordance with project requirements.

Three asphalt compactors from Caterpillar


Caterpillar's CB54, CB54 XW and CB64 asphalt compactors can be used on all phases of asphalt compaction, reducing the need for a variety of rollers. They work well as a breakdown or intermediate rollers because of their high compactive forces and due to the high pounds per linear inch (PLI) exerted by these machines, they also provide excellent results when working in the finish position. Typical applications include highways, city streets, county roads, lane additions, industrial sites, overlays, airport runways and other production-sized paving jobs.

The CB54, with 1700 mm (67-inch) wide drums, provides a high static force and competes in the 8 to 11.3 metric ton class of asphalt compactors at 10 804 kg (23,818 pounds). The CB54 XW, with 2000 mm (79-inch) wide drums, is designed for wider lane paving and also competes in the 8 to 11.3 metric ton class of asphalt compactors at 11 898 kg (26,230 pounds). The CB64, with 2130 mm (84-inch) wide drums, is designed for wide width paving and provides a maximum weight of 13 740 kg (30,291 pounds).

The new frame design provides a clear view to the drum surfaces and spray bars, allowing the operator to easily monitor water spray performance. The water spray system features a single tank, dual pumps, dual spray bars, and triple filtration that provides redundancy in the system and ensures reliable performance to keep the machine on the mat. Customers will appreciate the dual spray bar performance on polymer-modified mix designs, rubberized asphalt and other mixes that have a tendency to stick to the drums.

Depending on operating conditions, the operator can now choose between single or dual spray bar operation. The CB54 XW and CB64 models are equipped with 18 spray nozzles mounted over each drum, while the CB54 utilizes 14 nozzles.

The five amplitude vibratory system offers a wide range of amplitudes that apply extensive amounts of force for superior performance on thick lifts and tough mix designs. Versa Vibe is a multi-purpose, vibratory system that can handle a variety of mix designs. This system provides two, high amplitude/low frequency settings for tough superpave mix designs, and two, high frequency/low amplitude settings to match higher paving speeds. The dual amplitude/dual frequency vibratory system is similar to Versa Vibe, however the dual amplitude/dual frequency system only utilizes a single amplitude with each frequency. An adjustable auto-vibe function allows the operator to determine when the vibratory system should engage upon starting out or when changing direction.

CW Enterprises changes the function of Pull Grader


CW Enterprises offers a grading option for large construction sites and road building. The Pull Grader is built from older motor graders. The old graders get stripped down, rebuilt, and reworked into a pull type design. The Pull Grader was originally designed for agricultural use, including drainage and levelling. The weight of the unit and its ability to penetrate the soil in tough conditions also make it very useful on the construction site. The Pull Grader can be pulled with virtually any power unit however 250-hp to 400-hp 4WD Ag tractors seem to be the best fit.
There are some definite advantages to the pull type design. With the added length of the grader they do an excellent job of levelling and also work well in soft and wet soil. Another reason they work so well is there is a lot more horsepower and traction for pulling the grader through tough spots where a motor grader would spin out. The company says you can move the same amount of dirt with a 25,000-pound Pull Grader as you would a 40,000-pound motor grader. CW Enterprises also custom conversions as well. The standard pull grader is 34 feet long, weighs 22,000 to 25,000 pounds, has a 14-foot moldboard, 14 x 24 rear tires, and requires four hydraulic remotes.

Heavy Equipment Operating Engineer


Whether working as heavy equipment operators, mechanics, or surveyors, operating engineers can be found on any project using construction equipment. "Heavy equipment" is the blanket term for numerous types of machines: cranes, bulldozers, front end loaders, rollers, backhoes, graders, dredges, hoists, drills, pumps and compressors are just some of the equipment used by operating engineers. We are also called hoisting and portable engineers because the equipment we operate lifts and/or moves.

In most cases, if it can push, pull, pump or lift material, rolls on tires or crawls on tracks like a tank, it’s the work of IUOE. On virtually all construction projects, operating engineers are the first workers on the job and the last to leave. Our work is essential to a smooth-running construction project.

Although many members have a favorite type of machine to operate, operating engineers are masters of a variety of equipment. This versatility keeps us employable because employers' needs vary from project to project.

Heavy equipment mechanics and surveyors also are very important contributors on any construction job. Mechanics repair and maintain the equipment used on the job, requiring a thorough knowledge of many types of equipment. Skilled mechanics are critical because if the equipment isn't running when needed, an entire project can come to a screeching halt.

Surveyors use expertise in linear and angular measurements to lay out the geographical boundaries of a construction project. A surveyor must have a good command of advanced math principles because this type of work is extremely precise.

Heavy Equipment career starting with Heavy equipment training school

When talking to those who dream of a heavy equipment career, it can be hard work trying to get them to think realistically. As with most careers, you can’t expect to start at the top - after all, if you start at the top, the only direction you can go is down. Operating a large excavator or bulldozer is not out of the question, but you do have to get the basics right first and to then work your way to more responsible roles.

If you are considering a career in heavy equipment, start by thinking like an employer - who are you going to employ and what sort of jobs are you going to give them? Novices are obviously going to get the more mundane easy jobs. The harder task will go to those that have experience. Just remember, those experienced operators once started at the bottom, as you will. How they applied themselves to the various tasks then reflected in the types of jobs they were asked to do - the more they applied themselves and learned about their roles, the more difficult the tasks.

So starting with the basics then becomes important. Heavy equipment training that exposes students to a range of equipment and a range of tasks is the best start. Hands on training is obviously the best way to learn. Standing behind someone and watching them may teach you how to use the controls, but it doesn’t give you a ‘feel’ for the equipment. There is so much more to learn by actually sitting in the operator’s seat. Your hands and feet play an important role in ‘feeling’ what the equipment is doing - for example, is it straining, is it hitting rock, and what about the many other situations?

This is what is often termed ‘instinctive’ control of your equipment. Your body feels what is happening and acts almost before your brain clicks into gear. The more hands on experience you gain, the more control you will have over your equipment. ATS Heavy Equipment Operator Schools have been training prospective heavy equipment operators for decades. We can’t teach you ‘instinct’ - you develop that over time. We can, however, teach you to become highly proficient operators, ready to start in the work place and ready to gain that ‘instinct’ in the workplace. Your heavy equipment career starts by getting those basic skills right - and that’s where we can help you.

Komatsu Adds PC138USLC-2 to its Fleet of Near Zero Tail Swing Excavators

For increased power and performance in large quarry and heavy construction applications, Komatsu America Corporation (KAC) introduces the 651 hp, 251,000-lb PC1250-7 hydraulic excavator. The PC1250LC-7 replaces the company's P1100LC-6 as its flagship excavator for the construction market.

The PC1250s powerful Komatsu SAA6D170E-3 engine increases hourly
production by up to seven percent over the PC1100LC-6. The engine features an electronic controller and governor that fully complies with EPA Tier II air quality regulations. The PC1250LC-7 incorporates Komatsu's patented OLSS open-center, load-sensing and engine speed-sensing hydraulic system with four variable capacity pumps designed to enhance the machine's speed and
flexibility.

Two working modes, plus a heavy lift circuit allow the operator to match machine speed and power to the job. A unique two-mode boom setting allows the operator to electrically select a smooth mode for fine work and a power mode for heavy-duty applications.

Built to be a Low Cost Producer

New engine oil and filter change intervals are extended to 500-hours from the 250-hour interval recommended on the PC1100LC-6. The replacement interval for the hydraulic oil has been extended to 5,000 hours. In addition, the backhoe is equipped with a new wiring harness, DT type connectors and heat proof covering. These new features increase the reliability and durability of the
machine while reducing owning and operating costs.

The PC1250-7 is designed to reduce operating costs by extending
component life cycles. New hydraulic piping offers heat proof O-rings and face seal joints for added durability. The boom and arm offer increased section size and plate thickness, as well as continuous two-sided groove welding for maximum strength and reliability in rugged digging conditions.

The new Equipment Management Monitoring System (EMMS), accessed
through the color monitor panel in the cab, has the capability to schedule required maintenance and perform onboard diagnostics. Machine abnormalities are maintained in an electronic memory.

An optional Vehicle Health Monitoring System (VHMS) provides self-contained diagnostics, a preventive maintenance scheduler, gauge panels with operator warning override and downloadable machine performance history. Reduced costs and troubleshooting time, increased machine availability and reliability, as well as extended component life are the direct results of the VHMS monitoring system.

The PC1250-7 has fewer welds in the lower X frames and features
increased plate thickness for years of trouble free operation.

Automatic track tensioning and heavy guarding for the dual travel motors that power each track are standard on the PC1250LC-7. Travel motors are enclosed within the width of the track shoes for even further protection.

Operator Comfort Features

The PC1250-7's new, spacious operator's cab provides a comfortable work environment designed to maintain high operator productivity. The pressurized cab reduces noise levels 4 db(A) lower than the PC1100LC-6 and keeps dust and other particles from the cab's interior. The viscous damping mount system helps to minimize noise, shock and vibration in rough working
conditions. The inclined dashboard, one-piece-right-hand window, and spacious ceiling hatch increase visibility to all sides of the cab. The cab also is equipped with multi-adjustable seat and large-capacity, electronically controlled AC/heater/defroster systems to sustain operator comfort in any weather.

Versatility Is Key

Komatsu will offer the PC1250-7 in five different arrangements. The regular PC1250-7 features the standard length 21'1" track frame and 29'10" G.P. boom, and three different arm lengths. This configuration meets many general excavating requirements. Next, the PC1250-7 is configured with the 24'3" track frame and the 29'10" G.P. boom. This arrangement is perfect where additional flotation or maximum craning ability is required. The PC 1250-7 is further built with a standard length 21'1 track frame, a 25'7" reinforced boom and a reinforced 11'2" arm.

Top loading off road dump trucks is the specialty of the PC1250SP-7. The SP (super production) has a standard length 21'1" track frame machine, a 25'7" reinforced boom and a reinforced 11'2" arm.

The PC1250-7 can also be configured as a material handler with options such as 55 through 70-foot material handling fronts, clamshells, grapples, magnets and cab risers. Whatever the application, the PC120-7 MH can be a highly efficient loading and unloading tool.

Finally, the PC1250-7 can be purchased as a loading shovel. Featuring the standard length 21'1" track frame, 18'6" boom and 13'5" stick, the PC1250-7 loading shovel is a highly refined performer in truck loading applications where it is necessary for the loading tool to set on the same level as the dump truck.

The Volvo HB2400 hydraulic hammer is designed for Volvo EC240CL and larger excavators and can break concrete and bedrock with a maximum impact of 6,000 pounds per foot.
The long, heavy piston matches the diameter and weight of the work tools for maximum transfer of energy from the hammer to the ground material. An integrally top-mounted accumulator guards against pressure peaks and helps the piston keep consistent power. And the pressure-control valve keeps the hammer striking at full force, even if hydraulic pressure from the excavator changes.

John Deere Series II ADTs with exclusive onboard weighing system


The four new John Deere Series II Articulated Dump Trucks (ADTs) are rugged six-wheel-drive units that provide powerful traction in demanding conditions. They are designed for maximum productivity, increased uptime and low daily operating costs, particularly in fuel efficiency, with Tier 3-certified engines ranging from 265 to 413 hp.


Onboard weighing systems are standard equipment on these trucks. They give operators overload protection, with mirror-mounted lights that alert the loading operator when the truck is nearing capacity. The payload weight information is also available through JDLink so owners and equipment managers can monitor truck utilization far away from the jobsite.


A fully automatic transmission with an integrated transmission retarder has improved transmission shift performance, allowing quicker acceleration out of the loading area for faster cycle times, along with decreased fuel consumption.
“Because John Deere ADTs already have a significant weight advantage and the lowest ground pressure among the top five ADT manufacturers, Deere trucks burn less fuel, particularly in high time-on-grade applications and poor underfoot conditions,” said John Chesterman, product marketing manager for ADTs, John Deere Construction & Forestry.


The tire pressure monitoring system lets the operator keep track of tire pressure from the seat, eliminating guesswork and time out of the cab. The owner can also monitor tire pressures from his desktop since all of the tire information is available via JDLink.
John Deere D-Series II ADT cabs have been updated with a modern, comfortable and convenient design, with lower sound levels and a premium, heated air suspension seat standard. The Series II ADTs feature push-button start and stop with a standard turbo cool-down timer. To help owners reduce costs, these trucks have programmable auto-shutdown timers to save fuel, reduce noise and minimize engine use at times when the trucks are not doing productive work.


Taking fleet management even further, Series II ADTs come with JDLink Ultimate as standard equipment.
An updated 25-button sealed switch module with integrated transmission and dump body controls makes the units easier to operate and ensures switch durability.


All John Deere ADTs feature fabricated, heavy-duty frames, axle housings and articulation joints for lower truck weights and reliable performance. The ribbed body design increases strength yet contributes to low ground pressure. The structure is also engineered to ensure a best-in-class frontal approach angle. Deere ADTs also have ground level fueling.
The 250D and 350D have dry disc brakes and axles with limited slip differentials, while the 350D and 400D have controlled traction differentials and wet disc brakes standard.
“Building and site prep contractors, quarries, and road builders are going to find Series II ADTs have the fuel efficiency, productivity, durability and reliability to keep them more productive at a lower cost per ton,” said Chesterman.

Concrete paving advances: paving mold and bar inserter


The new GOMACO 5400 series paving mold – introduced at the recent World of Concrete – was designed with a structural integrity that is unmatched in the industry, the company says. It features a new “box” design, 54-inch (1372mm) finishing length and a 0.5-inch (13mm) paving skin. The new paving system has a series of accessories including centre and sidebar insertion systems. It features a spreader plow, independent of the mold, or an optional auger to spread the concrete across the paving width. A newly designed strike-off is now mounted to the paver’s main frame, independent of the mold. The strike-off has a wedge-lock system for easy width changes and hydraulic height and crown adjustment. The new mold also features hydraulic Vertically Hinged Sideplates (VHS), self-contained to the inside of the mold, allowing minimum track clearance.


GOMACO’s IDBI attachment is now available on all new GOMACO pavers. The IDBI attachment is an independent unit providing dowel bar insertion behind a paver to form the transverse joint. No power or hydraulics is needed from the paver’s engine. A CAN cable connects the IDBI’s controls to the controller on the paver and allows the two systems to communicate. The new design features a new IDBI tray that is stronger, more compact and makes width changes easier. New adjustable-height bar extractors allow contractors to quickly and easily change the setup for different bar sizes for insertion requirements. Its new GOMACO G+ control system features the same graphical display as the G22 controller, with easy to learn and easy to understand controls. The IDBI information is presented in full colour, commands are presented in full text, and it is able to operate in multiple languages, by customer’s choice. The IDBI attachment has outriggers to aid in attaching the unit to the paver and also for loading and unloading the unit for transporting. The outriggers can be hydraulically lowered and placed on the ground to support the full weight of the IDBI as it is attached to or detached from the paver.

The difference between Gas and Diesel Tractor

Diesel compact tractor is superior to a gasoline garden tractor.

The First, diesel engine doesn't have the parts that normally wear out or give problems. There are no spark plugs, rotors, points, or distributor caps like the garden tractor. There is no carburetor either, that will gum up and be hard to start after being stored for a long period of time. Diesel engines can be stored for long periods of time and still start right up.

Secondly, diesel engines in most tractors are water cooled. This will allow the engine to run at a more consistent and cooler temperature, which will extend the life of the engine. The typical properly maintained diesel engine can run thousands of hours without breaking a sweat - and without having to be rebuilt.

Diesel engines will also make more power. Even though gasoline tractors may be a little quicker to start with, they can't begin to match the power and raw torque that diesel engines offer. Another reason why diesel tractors are better than gas is the available attachments.

Most gasoline tractors are equipped with a belly mower and don't normally have a three point hitch. This will severely limit the type of implements that you can use and also limit the tractors expandability.

Most blades and scoop implements won't work with a gasoline tractor. The drive train will also limit the type of implement you can use with a garden tractor.

The typical gasoline garden tractor is belt driven, while a belt drive won't pull as much load as a diesel powered tractor. You would probably not be able to use a box blade or tiller either with the average gasoline powered tractor.

Compact all-wheel-steer wheel loader


Wacker Neuson has expanded its compact equipment line with a new all-wheel-steer wheel loader that delivers excellent maneuverability and stability. The 1150 wheel loader features a 4-wheel steer system and rigid frame design and is the largest of the Wacker Neuson wheel loader line.
“The new 1150 is powered by a turbo-charged Deutz engine (77.8 hp) and has an exceptional power to weight ratio making this unit very fuel efficient and economical to run,” says Jay Baudhuin, compact equipment product manager for Wacker Neuson Corporation.


The 5.9-metric-ton model offers 9,127 pounds of tipping capacity even at full turn with a 1.5-cubic-yard standard bucket. “This machine offers superior break-out force,” adds Baudhuin. “It has the power and capacity to do the heavy lifting without sacrificing maneuverability and stability.”
The 1150 is user-friendly with a spacious operator station that allows for excellent 360-degree visibility and ergonomics. A single joystick operation allows for precise work with minimum effort and reduced fatigue. The hydraulically operated quick-hitch allows for efficient changing from one attachment to another without leaving the operator’s station.
Wacker Neuson’s new 1150 complements the already introduced 280 and 850 all wheel steer models as well as the four articulated models. “Now with seven models to choose from with a variety of power and performance ratings, Wacker Neuson wheel loaders are an economical alternative to skid steer loaders as they can perform the same tasks, faster and more smoothly on the job,” says Baudhuin.

On/off highway excavators have greater capacity


Gradall Industries, Inc

The new XL 5300 III excavator is the largest model in the Gradall excavator family of on/off highway machines – with greater capacity as well as the ability to work efficiently in any direction.
It has an operating weight of 51,216 pounds (23,231 kg) with a maximum lift capacity of 13,508 pounds (6,217 kg). Rated boom force is an impressive 24,941 pounds (111 kN) while bucket breakout force is rated at 25,405 pounds (113 kN).
New operators can become more comfortable with this model faster thanks to a switch in the cab which provides a choice of SAE, Deere or Gradall joystick control patterns.
A standard “bucket shake” mode, controlled with a joystick button, allows operators to more evenly distribute fill dirt and rip-rap.
A single Detroit Diesel Mercedes engine delivers 173 horsepower to the upperstructure as well as the carrier. The chassis features the new Series III counterweight design that creates a shorter tail swing – a big plus when working in tight quarters or along highways. But even with a compact counterweight design, the machine has excellent working boom reach to 33 feet, 10 inches (10.3 m) and digging depth of 24 feet, 7 inches (7.5 m).

Recycle systems enhance cost efficiency


Asphalt Drum Mixers, Inc.

Asphalt Drum Mixers offers four models of portable and stationary recycle systems allow plants to use milled material in hot mix asphalt (HMA). Since recycled asphalt pavement (RAP) is much cheaper than virgin aggregate, the result is a less expensive finished product that maintains the high quality of a pure virgin aggregate mix. Based on conditions and type of plant, up to 50 percent of the HMA can contain recycled pavement.
ADM’s recycle bins feature a 15-ton capacity. A tapered discharge opening leads to the direct-drive belt feeder which has a five-horsepower motor, multi-ply belt, self-cleaning tail pulley and adjustable skirt boards.
To transfer RAP from the bin, the recycle system includes a heavy-duty weigh conveyor that features a channel frame and wind protection for accurate weighing. The conveyor is two-feet wide and, depending on the model, between 45- and 65-feet long. It introduces RAP to the dried aggregate mix after the heating process.
An optional lump breaker is available to break down large pieces of RAP into a useable size. Single- and double-deck scalping screens are also available to ensure oversized material does not enter the aggregate mix. Other options include air cannons, grizzlies, bin extensions, adjustable legs with sand shoes, and a skid with bolt-on support legs.

Uniquely-designed lift arm on articulated loaders


Gehl Company

Gehl’s new compact articulated loader models – 140, 340 and 540 – feature tipping loads ranging from 1,900 to more than 5,100 pounds (when not articulated) and rated operating capacities from 950 to more than 2,550 pounds. Engines range from 23 hp on the 140 model to 47 hp on the 540. They can use most universal-type attachments, putting tools customers already own to good use.

A heavy-duty oscillating joint offers 45-degree turning angles to the left and right and 10 degrees of oscillation in both directions. The bucket and tires follow a constant turn radius, so the rear tires of the loader follow the path of the front tires. Narrow machine widths, as narrow as 41 inches on the model 140, allow access to tight, confined spaces that most skid-steer loaders with comparable operating capacities cannot access.

Lift arm and bucket float features allow for “floating” of the lift arm and bucket for light scraping and rearward leveling actions.
The uniquely-designed lift arm on the Gehl articulated loaders is designed to achieve maximum strength, excellent visibility and fast cycle times. The parallel-type linkage on the models 140 and 340, and “Z” bar-type linkage on the model 540 provide excellent bucket breakout forces from 2,433 lbf. on the model 140 to 10,749 lbf. on the model 540. The unique linkage design allows for mechanical self-leveling action in both the up and down directions, excellent bucket dump angles at the mid- and top-ranges of the lift path, as well as outstanding forward reach.

Massive investment by JCB results in industry’s cleanest engine


March 26, 2010 - JCB reports that they have made one of the biggest investments in their history to develop the off-highway sector’s cleanest engine in readiness for incoming emissions legislation.

The company has invested around £80 million (CAD $121 million) in researching and developing a new combustion system for the new JCB Ecomax T4 4.4 litre engine - the latest generation of JCB Dieselmax engines. The company says that the investment has delivered an industry-first solution which eliminates the need for any exhaust after-treatment and delivers cost savings for mid-range customers.

The engine is now undergoing full in-field testing before going into production in 2012 to meet Tier 4 interim/Stage 3B legislation.

The key benefits of the innovation are:
* Reduced fuel consumption
* Reduced cost of ownership
* Better reliability
* Better packaging and no compromise of machine design

Alan Tolley, JCB’s Director of Engine Programmes, said, “Meeting Tier 4 emissions legislation is a massive challenge but also a huge opportunity for innovation; an opportunity to come up with a solution that has real advantages for our customers. We believe the result is not only the off highway sector’s cleanest engine, but a first for our industry.

“The expectation for the first part of Tier 4 interim/Stage 3B legislation was that to achieve these really low particulate levels you needed to fit a Diesel Particulate Filter (DPF).

“But when you look at that technology for our particular part of the market, namely mid-range construction equipment, we see there are some real disadvantages with that solution, in particular increased fuel consumption through increased back pressure to the engine. Also, in many applications load cycles are light and the DPF doesn’t self-regenerate so you have to force it to do so and it needs fuel to do it.

“Our strategy therefore has been to meet Tier 4 interim emission standards without a DPF but also to achieve this without any exhaust after-treatment. We have focused our research and development efforts on a high efficiency combustion system; in other words, we have made sure we don’t create the pollutants to start with rather than try and deal with them later. This approach also gives us very low fuel consumption levels.

“The solution we have come up with gives significant advantages for our customers for packaging and integration. On machines there is not much spare room in the engine compartment and we had a lot of discussion about how to optimize the machines, their design and functionality. The risk with something like Tier 4 is that in order to package everything you have to compromise those elements and we were not willing to do that which is what drove us to pursue a different technology solution.

“One of the advantages we have as a company that makes machines and engines is that we can come up with a final machine product which is better optimized.

“The real end user benefits come in the shape of reduced cost of ownership and reduced fuel consumption and better reliability. We see DPFs as a significant reliability risk; that has certainly been the experience in the automotive sector. We knew the emissions limits were very challenging but we always had the belief and objective of achieving it without putting the onerous burden on our customers.”

Better by design
Since its launch in 2004, the JCB Dieselmax engine has undergone continual development. More than 100,000 engines are now working in the field globally, recording class-leading levels of performance and reliability. The latest developments will see the Dieselmax engines cleanly past the Stage IIIB/Tier 4 Interim legislation that will come into effect for engines of this size in 2012.

As many engines within the 129kW (75-175hp) range are used in plant and equipment that is operated under variable light loads, there can be concerns about Diesel Particulate Filter (DPF) regeneration, with the engine management system having to force the regeneration process by burning additional fuel. This is not only inefficient but can result in additional service requirements, substantial cost increases and the risk of damage to the DPF if a contractor uses a high sulphur fuel.

To achieve the next round of emissions regulations, JCB Power Systems has worked closely with research and development specialist Ricardo, using computational fluid dynamics, finite element analysis and a Ricardo designed combustion bowl to perfect the combustion process.

With second generation common rail fuel injection technology, injection pressures have been raised to 2,000 bar and nozzle hole geometry has been refined to provide highly effective atomisation and distribution of the fuel within the cylinder. JCB has incorporated variable geometry turbochargers on all but the lowest powered 55kW Dieselmax engine, which falls under a slightly different emission regulation. Cooled Exhaust Gas Recirculation (EGR) is also used to clean up the exhaust gases before they are passed from the engine. This means that there is no requirement for any exhaust after-treatment components to meet these emissions levels on the 4.4 litre JCB Ecomax T4 engine.

The company has worked with fuel system and electronics specialist Delphi to develop an electronic control system with a form of learning capacity, that will ensure that the engine stays within its intended parameters even as the components settle throughout their design life.

Benefit to the customer
As well as there being no need to fit a costly exhaust after-treatment system, there has been no requirement to increase the cooling pack size or to reduce service intervals from their standard 500 hours. In addition, under test conditions, the engines have been achieving a 5-10 percent fuel consumption improvement compared to the previous generation.

The engine design is also future-proofed, as the structural architecture, the componentry and systems will remain the same for Stage 4/Tier 4 Final regulations in the future, at which time exhaust after-treatment for NOx reduction may be unavoidable.

Investment in the future
JCB has invested heavily in its Power Systems business in Derbyshire, UK, to meet the requirements of its customers and legislators. The original 4.4 litre Dieselmax 444 engine has been joined by a 4.8 litre Dieselmax 448 version, while power ratings have been extended at both ends of the scale.

JCB Power Systems has increased its research and development team by 40 percent, investing further in the JCB Dieselmax range.

Compact Excavators Mature

Sales of compact excavators have declined from their all-time high of 28,000 in North America in 2007, but manufacturers have not let up improving these little diggers. In fact, many features typically reserved for larger excavators have migrated to the smaller machines.

“When we brought out our D-Series excavators, we made a lot of changes that brought a lot of our technology and experience from large excavators to the small ones,” says John Deere’s Mark Wall, product marketing manager for excavators. “For example, we gave the compact machines two-speed propel with auto-shift in it. So if you’re propelling up a hill and you turn, or put the blade down, the excavator will automatically shift into low and give you higher propel power.

“We also offer auto-idle, which is a take-off from a larger excavator,” says Wall. “If you’re working a machine and then you don’t operate the levers for four or five seconds, the excavator will automatically go into low idle, to conserve fuel. And it reduces noise on the job site.”

Other improvements from Deere include a high-backed suspension seat, cup holders, and 12-V power outlets.

Improved Fuel Efficiency
Bobcat also has auto-shift and auto-idle—and incorporates load-sensing hydraulics into its 3-ton to 4-ton machines. Load-sensing hydraulics spring into action on demand only, says Tom Connor, excavator product specialist with Bobcat. If a hydraulic system is not being used, the pumps de-stroke into a “waiting” mode. That improves the fuel efficiency of the hydraulic system.

Bobcat launched its M-Series of excavators in April 2009, and the new machines boasted an all-new hydraulic system. “We had to do a completely different pump-and-valve package to get to the smoothness and response we were looking for without compromising speed,” says Connor. “And we needed efficiency in hydraulics so we could get by with less horsepower.”

Bobcat’s E32 and E35 compact excavators dropped in engine horsepower, from 40 to 33, to save fuel. “If you look at the list of customer priorities, the price of $4-per-gallon fuel sank in here,” says Connor. “Fuel economy became a driving force in the redesign of the machine.

“Additionally, we continue to expand the use of electric-over-hydraulic technology to accommodate improved ergonomics for operators. For instance, the new E32 and E35 excavators feature thumb-activated boom-swing control.” Bobcat offers 11 different excavator models, and nine of them are compact by definition (less than 6 metric tons).

All manufacturers have upgraded the engines in their compact excavators to comply with the EPA’s exhaust emissions standards. Deere offers five models of compact excavators, and four of them, including the recently introduced 40.5-horsepower Model 60D, all meet Interim Tier 4 standards. The fifth machine, the 14.8-horsepower Model 17D, meets final Tier 4 standards.

Those upgrades require tweaks to the cooling and fuel systems, Wall says.

Other changes at Deere include an angle blade for the 50D excavator. And Deere moved the control of the auxiliary hydraulic system from the right foot to the right-hand pilot lever.

Deere’s 60D excavator is the company’s latest addition to the compact lineup. With a standard arm and rubber tracks, it weighs in at 13,600 pounds and can dig 12 feet, 4 inches deep. With a long arm, the 60D can go 13 feet, 6 inches deep.

New From Caterpillar
Caterpillar offers 10 compact excavators with dig depths ranging from 6.8 feet to 13.7 feet. In 2008, the company upgraded the three largest machines in that range to D Series models—the 307D, the 308D CR, and the 308D CR SB (swing boom).

Yale's ERP030-040VT and ERP030-040VF lift trucks


Yale Materials Handling Corp. announces two new electric rider lift truck models—the three-wheel ERP030-040VT and the four-wheel ERP030-040VF. Both models provide lifting capacities of 3,000 to 4,000 pounds.

The highly maneuverable trucks are suitable for a variety of warehouse applications, according to the manufacturer. Their maneuverability is a result of their zero turn radius steer axles and dual AC drive motors. These independent, front-wheel motors rotate the drive tires in opposite directions, which places the center of turn between the drive tires. The lift trucks are available with a 36- or 48-volt, low-maintenance AC traction and hydraulic motor. These brushless AC technology motors provide powerful acceleration and faster travel speeds even with a load, while also supporting quick lift and lower speeds.

The lift trucks also feature four operator performance modes to allow performance to be tailored to the specific application and the operator's ability, increasing overall productivity and efficiency. The trucks' automatic parking brakes set automatically when the vehicle stops, reducing operator motion.

Kubota U55 Tight Tail Swing Compact Excavator

As the Largest Model in the Kubota U-Series, U55 Provides Power in Confined Work Spaces
Kubota introduces the U55, its largest model in the U-Series of compact excavators. The new Kubota U55 five-ton tight tail swing compact excavator is designed to provide outstanding power while working in tight job sites, where lifting capacity over the front is important. With a medium-length arm that enhances arm crowd force, a wide doorway and plenty of operator space, the U55 now replaces Kubota’s popular KX161 3 compact excavator.

“Contractors find the tight tail swing on the U55 to be the machine’s most attractive feature because it allows the operator to complete jobs quickly in confined work spaces,” said Keith Rohrbacker, Kubota product manager. “In addition, float is now intrinsic to all U55 standard and angle blades, increasing backfilling productivity and simplifying finish work.”

Power and Performance

With only 2.5 inches of tail swing overhang, the U55 is powerful, yet compact enough to operate efficiently and carefully in narrow work spaces; minimizing the chance of harm to panels and reducing long- term operating costs. A 47.6 gross horsepower direct-injection Kubota diesel engine features single-side servicing and includes an auto idle feature that conserves fuel and reduces noise level.

A new, load-sensing hydraulic system employs a combination of closed and open center controls to ensure strong digging forces and minimize “slow down” during travel when using attachments. The advanced load-sensing system provides optimum oil flow to each cylinder for smooth multifunction operation and enhanced fuel economy. Auto downshift travel motors smooth transitions through turns, and the optional hydraulic angle blade improves backfilling efficiency. Float is standard equipment on all blades and combines with high traction force to speed the operator on to the next job. These blades include a reversible bolt-on cutting edge to reduce operating costs.Two auxiliary hydraulics ports are also now available, expanding attachment versatility. This allows the operator to exchange hydraulic attachments and leave the thumb connected at all times, speeding attachment changes. With dual-element air cleaner and side-opening bonnets for convenient access to the service points, the U55 is easy to maintain.

Light, simple movements of the wrist are all that is required to operate the fully hydraulic pilot control system. The auxiliary hydraulics system is equipped with attachment flow presets from the control panel and thumb-ready sticks to speed attachment installation and changes. The U55 uses X-frame construction for high strength and excellent stability. The frame’s angle design has enlarged cleanout ports for easier cleaning that saves valuable time. The number of dual-flanged lower track rollers has been increased in the U55 to reduce vibration for a smoother ride and longer track life. Kubota matched the new three-pump load sensing system with the auto-downshift travel motors flawlessly, creating the ability to make quick, smooth turns.

Working in Comfort and Style

The sleek design of the Kubota U55 includes several features for operator comfort. Entry and exit is easy with wide doors and a large operator space along with optimal legroom. This model offers a comfortable high-back suspension seat and the arm rests can be adjusted to a comfortable position for the operator. Full pilot and ergonomically placed controls optimize well-being and reduce fatigue, improving overall performance.

The U55 features a new digital display panel, conveniently located for clear view and easy access, to provide vital information at a glance, and even notifies the operator when maintenance is due, reducing operating costs. Wide-ranging safety attributes include swivel and travel negative brake systems that hold the house and tracks in place on slopes. These systems simplify transportation and provide almost infinite positioning to improve load spacing. To help ensure optimum operator safety on job sites, all canopy and cab models feature a ROPS / FOPS certification. Even the operator’s investment is protected with Kubota’s own anti-theft system included as standard equipment. This anti-theft system is designed to keep equipment from getting stolen and to help eliminate the expense of theft recovery.

Kubota Tractor Corporation, Torrance, Calif., is the U.S. marketer and distributor of Kubota-branded equipment, including a complete line of tractors up to 118 PTO hp, performance-matched implements, compact and utility-class construction equipment, consumer lawn and garden equipment, commercial turf products and utility vehicles.
