Large-capacity torque converter
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. When working in load-and-carry applications, the loader achieves high gear ranges and maintains high travel speeds.
The torque converter features a lock-up function that activates in second, third and fourth 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.
“As a result of this combination, fuel burn is reduced,” said Braun. “All components are Komatsu designed and manufactured, so they are made to work in harmony for optimized performance, as well as for reliability and long life.”
Braun emphasized that Komatsu also designed the WA500-8 for durability. He said it offers a solid foundation for specialty WA500-8s, such as the yard loader or high-lift boom arrangements.
Braun pointed out that attention to details makes a difference, too. “We still incorporate a metal roof so operators are shielded when working in dangerous environments, like industrial plants, where products such as slag are present and may produce sparks. Protecting hydraulic lines and the wiring harness were factored in as well. Of course, we will work with customers on configuring the loader to their needs, such as adding wider tires to the WA500-8 for added stability.”
