LiuGong 922E Crawler Excavator
April 30, 2012

LiuGong Machinery Co.’s  922E excavator is the next generation crawler excavator from LiuGong, following in the tracks of the 922D, with additional power, control and operating efficiencies.  The 922E takes smart technology to a whole new level. The new E series machine boosts operating efficiency by 5% while reducing fuel consumption by 8% over the Series D.  The 922E  starts with LiuGong’s Intelligent Power Control System (IPC). The automatic power boost mode increases digging force by up to 10% for ten-second intervals, giving the operator an “on demand” boost for additional break-out power. The no-time-limit heavy lift system enables the operator to increase pressure to build force and reduce hydraulic flow to the attachment, while reducing speed, for added control during lifting operations.  An automatic boom descend regeneration system allows the boom to descend faster, increasing productivity while lowering fuel consumption. The 922E is powered by the highly-efficient Cummins QSB6.7 diesel engine rated at 127kw, 9% greater than the 922D.
