Komatsu America Corp. Launches New WA470-7 Wheel Loader

Komatsu America Corp. introduces 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 Tier 4 Interim and EU Stage 3B emission certified. Built upon a proven Tier 3 engine platform, Komatsu has leveraged its leadership in technology and innovation to design a more environmentally-friendly engine that increases power while decreasing fuel consumption by approximately 8 percent, compared to the WA470-6.
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 Tier 4 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 when compared to machines not equipped with KOMTRAX. The technology also allows for remote diagnosis by the distributor and provides a wealth of other information to drive business efficiency and productivity.
New features of the WA470-7 include:
• EPA Tier 4 Interim and EU Stage 3B Emission Certified Engine
Built upon proven Tier 3 technology, the SAA6D125E-6 engine provides lower emissions while also lowering fuel consumption. The Komatsu Tier 4 Interim engine uses an advanced electronic control system to manage air flow rate, fuel injection, combustion parameters and aftertreatment functions to optimize performance, reduce emissions, reduce fuel consumption and provide advanced diagnostic capability.
As a leader in hydraulic technology, 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.
• Large Capacity Torque Converter with Lock-Up
The WA470-7 has a newly designed Komatsu Large Capacity Torque Converter with Lock-Up as a standard feature. This 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 (38.3 kph).
The wheel loader has greater productivity in V-cycle applications because of the increased tractive effort. The faster hill climbing ability allows the WA470-7 to up-shift gears faster because of improved acceleration. The wheel loader can also achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry applications. In most applications, production is increased and fuel consumption reduced, resulting in improved fuel efficiency.
• Enhanced Operator Environment
The new cab provides a more comfortable and quieter work environment so the operator can maximize productivity. 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. An auxiliary input has also been added to connect an MP3 player or other device along with two 12-volt ports that have been incorporated into the cab.
A new high resolution 7” LCD monitor features enhanced capabilities and displays information in 25 languages for global support. Using the monitor, the operator can easily modify settings for items such as the Auto Idle Shutdown or the auto-reversing fan. The operator can also check operational records, such as working hours or fuel consumption; monitor the KDPF soot load; or check how much time is required before the next maintenance interval. 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.
• Customer peace of mind is standard because of Komatsu CARE®
Komatsu remains focused on lowering the customer’s ownership costs by engineering machines with increased fuel efficiency and productivity. Komatsu CARE® complimentary scheduled maintenance is standard on all WA470-7 wheel loaders for three years or 2000 hours (whichever occurs first). Services are performed by factory certified technicians using only Komatsu genuine parts and fluids. Also included are two complimentary KDPF exchanges at 4,500 hours and 9,000 hours within the first five years.
• Convenient Maintenance and Serviceability
The WA470-7 provides easy service access in order to reduce downtime. The new model has increased cooling capacity, wider cooling fin spacing and a standard auto-reversing fan to help keep the radiator clean. The machine is equipped with the exclusive Komatsu Equipment Management Monitoring System (EMMS), which provides enhanced diagnostic features that give the operator and technicians greater monitoring and troubleshooting capabilities. EMMS continuously monitors all critical systems, as well as the planned preventative maintenance schedule, and provides troubleshooting assistance to minimize diagnosis and repair time.
Note: All comparisons and claims of improved performance made herein are made with respect to the prior model, WA470-6, unless otherwise stated.
