Feature of Komatsu's New WA470-6 Wheel Loader


New Large Capacity Torque Converter
Similar to WA480-6, WA470-6 has a newly designed Large Capacity Torque Converter that provides excellent tractive effort, improved acceleration and improved hill climbing ability. The machine has greater productivity in V-cycle applications because of the increased tractive effort. The improved hill climbing ability allows WA470-6 to up-shift gears faster due to the improved acceleration, achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry or hopper feeding applications. In either application, production is increased and fuel consumption maximized resulting in improved fuel efficiency (tons/gal).

Increased fuel efficiency and maximum productivity
WA470-6 is powered by a Komatsu SAA6D125E-5 diesel engine with an Electronic Heavy Duty Common Rail fuel injection system that provides fast throttle response while optimizing fuel combustion. The engine is EPA Tier 3 emission certified without sacrificing power or machine productivity.

Fuel consumption is greatly reduced because of the high-torque engine and the large capacity torque converter, as well as the CLSS (Closed-Center Load Sensing System). With two selectable operating modes that adjust easily, the engine effortlessly adapts to different working conditions. The E mode provides maximum fuel efficiency for general loading and the P mode has a maximum power output for hard digging operation and hill climbing. For load-and-carry or hill-climb operations, the torque converter with optional lock-up transmission provides increased production efficiency, reduced cycle times and optimum fuel savings. An Eco Indicator informs the operator when the machine is maximizing fuel efficiency.

Easy maintenance for a reliable machine
Using strict quality control, Komatsu manufactures all machine parts with an integrated production system to create a reliable machine with very low maintenance costs and easy service access. Equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System), the operator stays informed of all machine functions on the easy-to-read monitor. An automatic reversible hydraulic radiator fan allows the operator to quickly clean out the cooling system at preset intervals or with the flip of a switch.

New large cab provides excellent operator environment
The wide and spacious cab of WA470-6 can reduce operator fatigue and increase productivity. The wide pillar-less flat glass affords excellent front visibility, and the wiper arm covers a large area for excellent visibility on rainy days. The cab's low-noise design of 72 dB (A) creates a comfortable working environment.

With its built-in ROPS/FOPS structure to protect the operator, the new roomy cab is mounted with Komatsu's unique viscous mounts to keep noise at a minimum and provide a low-vibration, clean operating environment. The layout of the cab has also been improved for easy access to levers, and the air conditioner has been relocated to the front of the cab to increase seat reclining and backward slide adjustment.

Easy Operation
With new Pressure Proportional Control (PPC) control levers, the operator can easily operate the work equipment with fingertip controls, reducing fatigue and improving fine work equipment control and productivity. The work equipment lever console can be adjusted, as can the large arm rest to provide the operator with a variety of comfortable operating positions.

Motor Graders Lay The Foundation Of A Smooth Ride

Building modern roads would be rather difficult without motor graders. One of the reasons we have such good highways is because of the work done by motor graders. They put the finish on the foundations of our roads.

When we drive along a highway, what we see is the finished product. What we don't see is what is sitting below the road's surface. In most cases, bulldozers and loaders work together to cut out a rough road. Motor graders then come in and cut that rough road back to a level and smooth base. If road base or other materials need to be added, it is the grader that levels this out, once again to a smooth surface.

I said that motor graders provide a level surface. This is not quite right. All roads have a slight slope to them. This slope is very precise since it is designed to help cars stay on the road yet encourage water to quickly run off the road. Motor graders use laser technology to get that precise slope in the road's foundation.

Motor grader operators are amongst the elite when it comes to heavy equipment operations. The position is well paid when compared to other operations, the work more precise and hence more challenging, and they are a part of a well oiled team that steadily builds our highways.

Becoming a motor grader operator is not that difficult. Complete a heavy equipment operator training course that includes motor grader skills then hit the workplace to put your new skills into practice. Before you know it, you will be one of the elite operators on a construction team - leading the way to providing us with first class roads to drive on.

Volvo to equip all general purpose machines with CareTrack telematics system as standard



Volvo Construction Equipment has announced it will fit as standard its remote monitoring (telematics) system on all larger machines – along with a no charge 36 month CareTrack service subscription.

Under the plan, all newly produced larger machines (wheel loaders over 10 tonnes, articulated haulers, excavators over 12 tonnes, motor graders) ordered for markets with CareTrack availability, will be standard equipped with telematics and will be delivered with a no charge, 3-year CareTrack customer subscription that enables owners to enlist the full range of benefits available with remote monitoring.

“Volvo Construction Equipment feels that remote machine monitoring is a feature with high business value for the customer and we want to accelerate its adoption throughout our various market segments.” says Tomas Kuta, President of Customer Support for Volvo Construction Equipment. “Every segment we participate in is being driven toward increasingly sophisticated business approaches by the combined influences of environmental and safety concerns, globalized economies and ever more demanding end customers. Higher adoption levels of telematics and the services that can be delivered using the technology will enable our dealers to more effectively tailor and deliver solutions for our customers.”




CareTrack is Volvo Construction Equipment’s state-of-the-art telematics system used to manage a machine’s productivity and maximize its availability for work. Using GPRS (mobile network) or satellite technology to send information, data is available securely and instantaneously to any remote online connection. Through fault reporting and activity warnings and by facilitating remote diagnosis, the goal is that machine problems will be identified sooner and resolved faster. Machine operation and deployment can be optimized via functions that monitor fuel consumption, location, hours of operation, speed and approaching service intervals. Combined with Volvo's remote self diagnostics (VCADS) and software productivity tools (MATRIS), CareTrack provides the most comprehensive uptime and productivity solution in the industry.

“Through constant machine monitoring, CareTrack can deliver the extra efficiencies that our customers need by ensuring machines are available for work and that they perform that work in the best way possible.” Says Mr. Kuta. “Telematics have come a good distance in a fairly short time. Previously customers have had to make a purchase decision about CareTrack installation and we feel at times the potential benefits available with its use in their particular application has not been clear to them. Further, it was not available on as many machine models as we will now equip. This move is a statement to our customers that telematics are becoming a ‘must have’ for ongoing competitiveness in their business - and we are committed to their success.” says Mr Kuta. “Soon, the value of CareTrack will be as self evident as other industry technologies like GPS grade control – and our customers will be among the first to wonder how they managed without it.”

CareTrack is available on the following machine models

Truck-mounted AC generators gaining traction with fleets

Chassis-integrated, PTO-driven generators turn trucks into mobile power stations that take serious AC power on the road


30kVA to 180 kVA Real Power components: The Real Power AC generator system consists of a few simple parts that do not interfere with your truck’s existing electrical system. 1.) Dash Switch 2.) ECM 3.) PTO Gear 4.) 30kVA to 180kVA Generator 5.) Power Distribution Panel

Real Power, a manufacturer specializing in the design and integration of patented, truck-mounted, mobile AC power generation systems, announced recent sales growth that it attributes to an increased demand from fleets.

“Fleets are utilizing Real Power technology to bring up to 180 kVA of AC power to remote work sites to operate power-hungry equipment and to bring emergency power to critical-care medical clinics,” said Chris Gray, sales manager for Real Power. “Organizations are seeing new potential for vehicles they are already operating or are considering purchasing.”

Vecoplan, LLC, a worldwide leader in shredding technologies and complete recycling systems, recently chose Real Power generator systems to operate shredding mechanisms on the most powerful mobile document destruction equipment on the market.

“Previously, high-volume document destruction often required transportation of material to an off-site shredder,” said Todd Carswell, Vecoplan’s vice president of technical development. “Moving classified waste is problematic for hospitals, banks, pharmacies and similar businesses that require on-site document destruction. The extraordinary AC power generation achieved with a Real Power system allows us to mount an ultra-high volume shredder on a vehicle that can be driven to virtually any location. Operators can now destroy large quantities of sensitive materials faster and without the liabilities associated with transporting them".



30kVA to 180 kVA Real Power generators: The 30kVA to 180 kVA Real Power generators for class 4 through 8 trucks mount to the outside of the driver’s-side frame rail, out of the way of other truck components. Like the 12kW and 15kW generators, no ground clearance is lost.

Carswell said that Vecoplan’s VST-42e Real Power-equipped shredding trucks are selling well and have virtually revolutionized the mobile shredding market.

The operator of a leading nationwide network of dialysis facilities also recently chose Real Power chassis-integrated generators as part of its plan to keep clinics up and running during power outages and related natural disasters.

“The network’s patients typically need dialysis every two days and delays can be life threatening,” Gray said. “When a recent storm temporarily disrupted Chicago’s power, the network’s leadership explored options for contingency plans that ultimately led to the acquisition of mobile generator trucks outfitted with Real Power technology.”

When a power outage occurs, Real Power-equipped delivery vehicles serving clinics in Chicago and other major metropolitan areas can be immediately deployed. The vehicles and selected clinics have been equipped with a simple-to-use cable interface; the vehicle is parked, cables are connected and a dashboard switch is flipped. Network staff members can perform the hook-up operation themselves and no electrician is needed.

With a diesel fuel capacity of 200 gallons, the trucks can arrive at the site ready to generate power for 48 hours or more without the need for refueling. Unlike traditional auxiliary generator sets that require fuel to be brought to them, the trucks can be driven to the nearest operating fuel station or can be refueled on-site.

30kVA to 180 kVA Real Power interface: Five colour coated cable connections and a sequence control mechanism make hooking up a facility to Real Power simple and easy.

There are plans to outfit more trucks that will serve other parts of the U.S. Clinics will share the cost of the truck that serves them, minimizing their individual expense. When the trucks are not being called upon to generate backup power, they will deliver supplies to network clinics, giving the organization a dual-use advantage.

“Before now, if you needed AC power delivered to a remote location or for an emergency, your choices were very limited,” Gray said. “For smaller power needs, you could haul around a portable generator or tap into an unreliable inverter-based system. And for larger power requirements, you could have a large gen-set delivered to your location.”

Gray noted that organizations with fleets have begun to choose Real Power over large generator sets because Real Power means one truck, one fuel source and maintenance that is as close as the nearest truck service bay.

“Real Power is built for the real world,” Gray said. “It is a field-tested, engineered solution with a proven track record in tough applications: construction, business services, government emergency command centres, municipal and public support services, military, farming, recreation, home use – the list goes on. And, Real Power offers a range of mobile power solutions from 12kW to 180kVA.”

FORKLIFT: Facts and Figures Forklift

The forklift is a powered truck fitted with steel forks on its front end, used to lift and transport material. The two parallel steel forks slide beneath the material, often loaded onto a wooden pallet or skid, and then hoisted. Most are fitted with small wheels and are really only practical on finished or paved surfaces. Some forklifts carry their cargo on one side of the vehicle; these are called sideloaders. Though small by comparison to most heavy equipment vehicles, it has become indispensible for the warehousing and manufacturing sectors. Major manufacturers of forklifts (by market share) include Toyota, KION Group, Jungheinrich, NAACO Industries, Inc. (which includes Yale and Hyster brands), Komatsu, Manitou, Mitsubishi, Nissan, Caterpillar, Clark, and Crown Equipment, though many more brands are available among used forklifts. (Over the years, many other brands such as Allis-Chalmers have either gone out of business or been assumed into larger companies through acquisitions.)

Forklifts are organized by class. Forklifts range in size and capability from small, hand powered pallet jacks, designed only to give ground clearance and move the pallet from one area of floor, all the way to diesel-powered driver-operated models of enormous size, used for moving raw logs and capable of loads up to 50 tonnes. Most common are those in the middle, either electric-rechargeable or propane-powered models approximately 6-10 feet (2-3 meters) in length, with forks on a sliding hydraulic mast of cylinders or rails, and capable of loads between one and five tonnes.

Forklift operators must be well trained to operate the machine safely and effectively. Because most models steer from the rear, manouevering quickly can take some getting used to. Additionally, moving with a load held high upon the forks can upset the forklift's low center of gravity, and risk tipping. To keep the forklift balanced, some machines have a counterweight at the back, though in most cases it is the actual engine or battery that acts as the rear weight. Most forklifts have an overhead guard above the cab to protect the operator from falling debris. The exception would be those motorized pallet jacks upon which the operator stands.

Prices for new, mid-sized driver-operated forklifts range from about $20,000 for a 4000-pound lift capacity to $77,000 for a model capable of lifting 8000 lbs.; used forklifts start at around $4000-$5000. However, for projects of limited duration, rentals might be more practical. Rental prices for light duty forklifts range from approximately $1000 to $1500 per week, or $2500 to $3500 per month.

BACKHOE: Facts and Figures Backhoe

A backhoe is a machine designed for excavation. It consists of a scoop or digging bucket on an articulated arm (also known as a stick or dipper); this assembly is typically mounted on the back of a tractor or front loader, enabling the operator to do many different jobs without switching to another piece of heavy equipment. However, the backhoe is not so called because of its rear-mounted scoop; rather, it is called a backhoe because of the way it draws earth back towards itself, rather than pushing it like a bulldozer.

The backhoe arm may also be used to connect to other attachments than a scoop, using an integrated toolcarrier (IT). Such attachments include augurs for drilling, hydraulic hammers for breaking up asphalt, asphalt grinders for milling road, grapples for pulling up roots and stumps, and compactors for compressing loose road material such as gravel. All of these attachments, its compact size, and its manoeuverability on wheels make the backhoe an extremely versatile and popular piece of heavy equipment machinery.

The digging bucket of a backhoe is much narrower than the bucket on the front loader, but is able, because of its articulated arm, to dig much deeper than the front bucket. Its narrow dimensions enable it to dig trenches quickly and effectively for laying pipe or cable, and preparing areas for concrete foundations, and drainage.

The first tractor equipped with a front loader and backhoe was developed in Britain by JCB in 1953. So dominant was JCB in their market that the British still refer to the machines as "JCBs"; the term backhoe is virtually unknown there.

Major manufacturers of backhoes include: Ammann-Yanmar, Case, Caterpillar, Deere & Co., Ford Motor Company, Hitachi, JCB, Komatsu, KPX, Massey Ferguson, Takeuchi, Terex, Terramite, Volvo, and John Allen & Sons.

Because of its popularity - Caterpillar alone reports having sold over 100,000 backhoe loaders since 1985—the laws of supply and demand have kept prices for backhoes very competitive. Used backhoe loaders can run anywhere from $5000 to $30,000, depending on the equipments age, capabilities, and included attachments. Rental prices for large, wheeled backhoe loaders start from around $1400 per week, or $4200 per month.

PUTMEISTER PUMP CAR


Fig. 1571-2
The Putzmeister M 42-5 is an especially compact and flexible truck-mounted concrete pump in the 40-metre class.

In the 40-metre class, Putzmeister will be presenting the M 47-5 and M 42-5 boom models with a roll-Z fold system. With their 5-arm booms, they can adapt particularly flexibly to different conditions on the building site, both for structural and civil engineering. During the machine's development phase, the focus was placed on offering the maximum possible working range, while requiring the minimum support area and providing considerable weight reserves for carrying additional pipes and hoses. The numbers bear witness to an impressive design: on the M 47-5, the width of the supports was able to be reduced to just 8.0 m at the front and 8.9 m at the back (M 42-5: front and back = 7.9 m). If the machine is stably supported on just one side using One Side Support (OSS) system, this figure is reduced again by some 30 %. On either boom model, customers can choose between three large-volume, low-wear pump units, which can achieve delivery rates of up to 160 m³/h. These machines represent the largest truck-mounted concrete pumps on a 4-axle chassis which Putzmeister offer for the European market.

BULLDOZER: Facts & Figures Bulldozer

The bulldozer, so called because of its pushing power, is a track-wheeled, driver-operated heavy equipment machine fitted with a broad flat blade. Its main purposes are for pushing large, heavy objects or piles, and for flattening and grading. Properly speaking, a bulldozer whose blade has been replaced with a hydraulic scoop is a tracked loader, not a bulldozer.

The origin of the name "bulldozer" is uncertain, but it is interesting to note that in the 1880s a "bull-dose" was a large amount of medicine suitable for a bull, and a "bulldozer" was a large calibre pistol and the person who wielded it (ie., someone who intimidates others).

Bulldozers were developed by the Holt company (today known as Caterpillar) from tractors used to plough fields. The tires were replaced with a rotary track system, allowing these vehicles to move effectively over soft and muddy ground. A military application was also recognized, and the first armoured tanks with rotary tracks rolled across Europe toward the end of World War I. Today, bulldozers themselves may be armoured for construction in a military environment, as they are in Israel.

The blade of a bulldozer comes in three main varieties: the Straight blade, a short blade with no lateral curve or sidewings, used for fine grading; the Universal blade, a tall curved blade with sidewings used for gathering and moving more material; and a combination blade, called the "S-U" blade, which is less curved and has smaller sidewings, and is used for pushing boulders and rock piles. Bulldozers may also be fitted with either a single- or multi-shank ripper on the back, useful for breaking up hard surfaces either into rubble for removal or ploughable land.

While demolition companies or companies specializing in road construction may find it practical to purchase bulldozers for regular use, smaller companies or those with more diversified services may find it more practical to rent or lease their heavy equipment, depending on the project size. Prices for new bulldozers can range anywhere from $100,000 to $600,000, depending upon the manufacturer, size, and features of the machine. Rental costs may vary from $1800/$2500 per week/month to $2500/$7600 per week/month, or even more, again depending on size and features.

CRANE: Facts & Figures Crane

The crane is a construction devise comprised of an arm, a winch, and a wire rope to create mechanical advantage and lift heavy objects. The arm may be hydraulically controlled and connected to a pivot point, or may consist of a vertical mast and a horizontal boom. Many different types of cranes exist, each tailored for a specific purpose, but they all work on the same general principles, particularly leverage.

Cranes may be thought of as the oldest of heavy-equipment machines, having been invented by the Ancient Greeks for the building of temples. Those cranes, right up until the Industrial Revolution, utilized human or animal power to turn the winch or move the crane, though sometimes they could be connected to a water or wind mill. The first mechanically powered cranes utilized steam engines in the late 18th or early 19th Centuries. Modern cranes are powered by either electric or internal combustion engines, and use hydraulics to create even more lifting power.

There are many types of cranes. The one seen most obviously along the skyline is the tower crane, which has a fixed base and is constructed on site and dismantled once a project is complete. These cranes employ a counter balance on the short end of the boom, while the long end does the lifting. Because of their height and their slender base, they must be engineered to withstand forces that would cause them to tip, and are often braced by the very structure they are building. Truck mounted mobile cranes , known as boom trucks, generally employ a telescopic crane mechanism, allowing them to minimize their size for travel to and from job sites. Floating cranes are constructed upon pontoons, and are used mainly in the construction of bridges and ports, though they are sometimes also used to move awkward loads off of ships, and in salvage operations. Some floating cranes have lift capacities of 10,000 tonnes.

Large construction companies may have several cranes among their heavy equipment. For companies which are not regularly using cranes on their projects, many industrial equipment rental stores exist. Rental prices run at about $4000 per week or $11,000 per month for a 5-ton boom truck with a 110-foot reach, while a taller Potain self-erecting crane may run upwards of $8500 per month, though rentals of these are often for a minimum of three months.

Facts & Figures Motor Grader

A motor grader, sometimes called a blade or simply a "grader", is a heavy equipment engineering vehicle used to create a finish grade for roads, airstrips, or other large, flat surfaces such as soil foundation pads for building construction. They prepare and maintain gravel roads, which can degrade into a "washboard" after rains. In paving construction, they prepare the base course for asphalt. In colder climates they may be used for snow removal, while in grasslands they may be used for creating dirt tracks where the absence of trees means there is no need of a bulldozer. In some countries they may also be used to create shallow v-shaped ditches along roadways.

Typical models have three axles. The engine and cab rest over the section between the rear two axles, while the blade for grading is suspended from the section between the hinge in front of the middle wheels and the front wheels. Steering is accomplished by the movement of the front wheels on the turning of the hinge.

Early graders were known as "pull-type" graders, horse-drawn modified carriages with a small gasoline-powered motor to drive the conveyor. Invented in 1903 by two entrepreneurs, the Russell grader was eventually pulled by a tractor. In 1928, Caterpillar, whose engines were already being used on Russell graders, bought Russell Grader Manufacturing, and in the 1930s new grader lines were developed, the forerunners of today's modern motor graders.

Major manufacturers of motor graders now also include Case, Grove, Hitachi, Ingersoll-Rand, Komatsu, New Holland, Veekmas-Oy, and Volvo.

Blade sizes range from 2.5 to 7.3 meters, and engine sizes from 125 to 500 horsepower. Some companies may choose to lease or rent motor graders, depending on the size or duration of the project. Rental prices range from around $13,000 per month ($4,300 per week) for a smaller model such as the CAT 140H, to $24,500 per month ($8,200 per week) for a larger model such as the CAT 16H. As with other heavy equipment, the rental price can in most cases count as equity towards purchase, if the contractor decides there will be enough work to justify buying the machine outright.

Wheel Loaders Buying Guide


Wheel loaders are a core component of many construction fleets. For digging, hauling, and scooping, they offer outstanding power and reliability. Here's what you need to know before purchasing a wheel loader.

What size do you need?
Wheel loaders come in a very large range of sizes. Most BuyerZone users choose either small loaders, around 50 to 80 horsepower (hp) with operating capacities of 2,000 to 5,000 lbs, or mid-sized wheel loaders that provide 100 to 300 hp and operating capacities up to 30,000 pounds or more.

The upper end of the wheel loader market consists of huge machines designed for use in mining or other large-scale hauling activities. These loaders can range from 500 to almost 1,500 hp and boast operating capacities measured in tons – 20 to 40 tons in a single scoop. In most cases, mid-sized loaders can get the job done.

Often, the physical size of the machine will limit you: if you need it to fit into a garage or through narrow passages, make sure you know what those size limits are before you choose a specific model.

What do you need it to do?
Full-sized wheel loaders can handle many different jobs thanks to a range of available attachments. The most common choice is a bucket: these can range from smaller, tougher rock buckets to huge buckets for scooping up light fill.

Wheel loaders can handle more than just buckets, though. They're popular in scrap yards, where they can lift large bundles of junk metal with grapples, and lumber yards, where they can handle massive logs with ease.

If you plan to regularly switch between attachments, a quick coupler makes switching more efficient. However, a coupler can also reduce overall capacity and breakout force, so it may not be worthwhile if you rarely change attachments.

Other considerations

* Older loaders use hand and foot levers to control the various functions – newer models feature much easier-to-use “pilot controls:” dual joysticks that provide full control with less stress on the operator.
* Cabs are becoming more like automobile interiors: they’re larger, provide better sight lines, and can include extras like suspension seats, climate control, and 12-volt outlets for cell phones or other accessories. These aren’t just frills: keeping the operator comfortable increases productivity.
* New wheel loaders are required to meet Tier-3 emissions standards set by the EPA. This makes them less polluting and can help reduce your average operating costs, as well.

Choosing a dealer
Buying a wheel loader is a significant investment – you can expect to pay anywhere from $50,000 to $150,000 for a new small to mid-sized loader. Due to this investment, you'll want to choose a dealer who will be around to support your purchase for years to come.

Look for dealers with significant experience in construction equipment. Find out how long they've been in business, how many manufacturers they work with, and if they offer a full range of accessories such as additional attachments, trailers, and replacement tires and parts.
