The XGC88000 Crawler Crane is designed with three independent power units. Each power unit is outfitted with a powerful 641KW (860hp) U.S. Cummins engine, the large power box space makes maintenance and repair work simple. To improve assembly efficiency, each power unit functions as a movable hydraulic power working station and can serve as a power source during the crane assembly/disassembly process. The three power units can serve as backup power units for one another.
