Liebherr LH 60M Wheeled Material Handler has a patented Energy Recovery Cylinder (ERC): a nitrogen-filled cylinder designed to partially compensate for the weight of the working attachment, boom, stick and load. As the load is lowered, the gas in the cylinder is compressed; as the load is lifted, the stored energy assists the lifting action. ERC enables the use of smaller hydraulic cylinders and reduces engine horsepower, Liebherr says. Liebherr Power Efficiency electronically ensures performance efficiency. The two technologies give the LH 60M a 5-percent increase in production and a 20-percent reduction in fuel consumption, compared to the predecessor model.
