Komatsu SmartLoader Logic

The WA900-8R provides Komatsu SmartLoader Logic, an engine control system. This technology creates enough
torque for each work phase. For example, engine torque needs are higher for digging in V-shape loading, but less when
driving with an empty bucket. This system optimizes the engine torque for all applications to minimize fuel consump-
tion. Komatsu SmartLoader Logic functions automatically and doesn't interfere with operation, saving fuel without
decreasing production.
