Komatsu America™s New Wheel Loader Built for Power
Posted By admin On January 27, 2009 @ 12:00 am In Boomerang | No Comments
Vernon Hills, IL, May 2, 2006”Komatsu America Corp. today introduced its new WA500-6 wheel loader. The powerful new machine delivers optimum performance and reliability. Designed for quarry, sand, gravel and industrial applications, the WA500-6 employs the latest technological advancements allowing operators to work comfortably and productively in a variety of conditions. The powerful WA500-6 has a net horsepower of 332 HP and an operating weight between 71,585 and 74,010 pounds, and all major components including the engine, torque converter, transmission, hydraulic units and electric parts are engineered by Komatsu.
The WA500-6 is equipped with the latest Komtrax technology which sends the machine operating information to a secure website utilizing wireless technology. Hour meter, location, cautions and maintenance alerts to name a few of its features are relayed to the web application for analysis. The Komtrax fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor, and provides a wealth of other information to drive business efficiency and productivity.
Special features of the new wheel loader include:
Powerful technology for optimal productivity
The new WA500-6 gets its exceptional power and work capacity from a Komatsu SAA6D140E-5 engine coupled with a new, large capacity torque converter and variable piston pumps. The large capacity torque converter dramatically improves the machine™s performance when loading trucks and climbing grades. The variable piston pumps combined with CLSS (Closed-Center Load Sensing System) delivers only the required amount of hydraulic flow necessary to the work equipment. By reducing the wasted flow of hydraulic oil, the amount of power necessary to move the pumps is reduced, improving performance. The rim pull is increased for better bucket penetration and reduced cycle times, all leading to higher productivity.
The engine complies with the new Tier 3 EPA emissions and provides improved fuel efficiency. By properly matching the large capacity and engine horse power, the engine works in a more fuel-efficient manner.
With two selectable operating modes that are easily adjustable, 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. In the low speed range, the low-noise, high-torque engine and the large-capacity torque converter reduces fuel consumption for maximum efficiency. For load and carry or hill-climb operations, the new torque converter with optional lock-up transmission provides increased production efficiency, reduced cycle times and optimum fuel savings.
The new wheel loader has an increased general purpose bucket capacity of 7.4 yd³ and can now load 32 ton trucks. There is also an optional 6.8 yd3 bucket for excavating or an 8.2 yd³ bucket for light materials. A wider tread and longer wheelbase improves the machine™s stability and enables operators to efficiently maneuver even the tightest job sites.
New cab design promotes excellent operator environment
Improvements to the cab design make it safe and easy for operators to work a full day, and increase productivity. The new roomy cab is mounted with Komatsu™s unique viscous mounts to keep noise at a minimum and provide a low-vibration operating environment. The cab has a built-in ROPS/FOPS structure to protect the operator. The layout of the cab has also been improved for easy access to levers, and the large armrests provide added comfort. The cab is equipped with EPC (Electronic Pilot Control) levers which make it easy for the operator to work all day without fatigue and to perform functions such as adjusting the bucket positions and digging angles with minimal stroke. The air conditioner has been relocated to the front of the cab for more room behind the seat and on the left side. This provides the operator with more room to allow for increased seat travel to more comfortably accommodate all operators.
The automatic transmission with ECMV (Electronically Controlled Modulation Valve) makes operating functions easier and more efficient and ensures a more comfortable ride. It automatically selects the proper gear speed based on conditions such as travel and engine speed, and includes two switches that make operating the machine easier. With the touch of a finger, the kick-down switch automatically downshifts from second to first when beginning the digging cycle; in reverse, it automatically upshifts from first to second. Conversely, the hold switch keeps the transmission fixed to either the third or fourth gear speed when auto shift is selected.
Easy maintenance for a reliable machine
To reduce costly downtime, the WA500-6 wheel loader was designed to provide easy service and maintenance access. Using strict quality control, Komatsu manufactures all machine parts with an integrated production system to create a reliable machine with very low maintenance costs.
The WA500-6 is equipped with the exclusive Komatsu EMMS (Equipment Management Monitoring System). The easy-to-read monitor keeps the operator informed of all machine functions, including fluid and filter change intervals and troubleshooting memory display functions. A reversible hydraulic radiator fan allows the operator to quickly clean out the cooling system with the flip of a switch.
