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.
