The Komatsu-designed power train has a large-capacity torque converter for optimum efficiency, including in V-cycle applications because the increased tractive effort does not require full throttle. It allows operators to up-shift gears faster for improved acceleration and hill-climbing ability. The loader achieves high gear ranges and maintains high travel speed when working in load-and-carry applications.
 
The torque converter features a lock-up function that activates in 2nd, 3rd and 4th gears and is effective for both load-and-carry and V-cycle work. Additionally, Komatsu’s SmartLoader Logic reduces the clutch engagement shock of the lock-up by controlling engine torque. The combination of these reduces fuel burn.

All components are designed and manufactured by Komatsu, so they are made to work in harmony for optimized performance as well as for reliability and long life.
 
“Because we use robust components and a high-rigidity frame in the standard WA500-8, we only need to upgrade certain items for the specialized loaders, such as the Fork Arrangement,” explained Adam Braun, Komatsu Product Marketing Manager-Wheel Loaders. “Other manufacturers producing similar machinery typically have to completely redesign their base products.”
