Komatsu America’s new WA500-7 wheel loader is powered by an EPA Tier 4 Interim and EU Stage 3B emission-certified SAA6D140E-6 engine with 353 net hp (263 kW) and has an operating weight of 76,611 lb (34,750 kg) when equipped with a 7.3-yd3 (5.6-m3) general-purpose bucket. Improvements include Smart Loader Logic, which can save fuel by adjusting engine torque to match the application. The WA500-7 provides easy service access, increased cooling capacity, wider cooling fin spacing, and a standard auto-reversing fan to help keep the radiator clean. A diesel particulate filter and regeneration system are integrated to keep the operator aware of its status, yet not interfere with daily operation.
According to Komatsu, the WA500-7 features a large-capacity torque converter with lock-up as a standard feature, providing improved acceleration and hill climbing ability, a higher top speed and lower fuel consumption. The lock-up function activates in second, third and fourth gears and gives the machine a maximum ground speed of 23.2 mph (37.3 km/h). Komatsu claims that because of its increased tractive effort, the wheel loader has greater productivity in V-cycle applications. It can also achieve higher gear ranges and maintain higher ground speeds when working in load-and-carry applications.
A ROPS/FOPS Level 2 certified cab provides a more comfortable and quieter work environment for the operator, featuring a redesigned dashboard and a high-back, heated air ride seat that has been relocated to improve visibility. A high-resolution 7-in. LCD monitor offers 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. Operators can also check operational records, such as working hours or fuel consumption; monitor the diesel particulate filter; or check time remaining for the next maintenance interval. A separate high-resolution back-up camera is standard equipment on all WA500-7s.
