Rolling Meadows, Ill. - Komatsu America Corp. introduced the WA470-7 wheel loader. With a net horsepower of 272 hp (203 kW), the WA470-7 is powered by a Komatsu SAA6D125E-6 engine, and is EPA Interim Tier 4 and EU Stage 3B emission certified. Built upon a Tier 3 engine platform, Komatsu has designed a more environmentally-friendly engine that increases power while decreasing fuel consumption by approximately 8 percent. It uses an advanced electronic control system to manage air flow rate, fuel injection, combustion parameters and aftertreatment functions.
Weighing in at 52,007 pounds (23,590 kg), the WA470-7 features improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability to maximize productivity while lowering operating costs.
The WA470-7 is equipped with the latest KOMTRAX technology, which is fully integrated with Komatsu’s iT4 technology. Machine operating information such as operating hours, fuel consumption, location, cautions and maintenance alerts are wirelessly relayed to a secure website for analysis. The KOMTRAX fleet monitoring system results in increased machine availability and reduced risk of machine theft. The technology also allows for remote diagnosis by the distributor.
Komatsu has also developed a hydraulically actuated Komatsu Variable Geometry Turbocharger (KVGT) and an Exhaust Gas Recirculation (EGR) valve, resulting in better precision and air management as well as longer component life. The Komatsu Diesel Particulate Filter (KDPF) has an integrated design that will not interfere with daily operation, but will keep the operator aware of its status.
The WA470-7 also features Komatsu Smart Loader Logic (KSLL), which provides optimal engine torque for the job required. KSLL allows for fuel reduction by decreasing engine torque when the loader isn’t working hard, such as when it is driving with an empty bucket. KSLL functions automatically with machine operation and results in saving fuel without decreasing production.
The wheel loader has a newly designed Komatsu Large Capacity Torque Converter with Lock-Up as a standard feature, which provides improved acceleration, faster hill climb ability, a higher top speed and lower fuel consumption. The Lock-Up function activates in 2nd, 3rd and 4th gears giving the machine a maximum ground speed of 23.8 mph.
The faster hill climbing ability allows the WA470-7 to up-shift gears faster because of improved acceleration. It can also achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry applications.
The WA470-7’s cab provides a more comfortable and quieter work environment. The front glass has been lowered and the dashboard has been redesigned to improve visibility. Electronic Pilot Control (EPC) levers and an F-N-R switch are part of a redesigned seat-mounted right hand console. A high resolution 7-inch LCD monitor features enhanced capabilities and displays information and records in 25 languages for global support. In addition, the monitor offers the operator the option of using the ECO Guidance (economy) function, which will provide operational tips to reduce fuel consumption. A separate high-resolution back-up camera is standard with every machine and is mounted on the right hand side of the console for operator convenience.
