The 922E crawler excavator from LiuGong has additional power, control, and operating efficiencies compared to its predecessor, the 922D.
LiuGong says the new E Series machine boosts operating efficiency by 5 percent while reducing fuel consumption by 8 percent over the D Series unveiled last year.
The 922E features LiuGong’s Intelligent Power Control System. The automatic power boost mode increases digging force by up to 10 percent for 10-second intervals, giving the operator an “on demand” boost for additional breakout 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.
