Liebherr Construction Equipment Co. introduced the LH 60M and A934 HD ERC wheeled material handler’s at the ISRI Tradeshow held at the Mandalay Bay Resort in Las Vegas, Nev.

The LH 60 M continues in the “Liebherr Handler” series of design specific material handling machines.

The LH 60 M and A934 HD ERC feature the energy recovery cylinder (ERC). The ERC is a nitrogen filled energy storage cylinder designed specifically for use on material handling equipment. The cylinder works by partially compensating for the weight of the working attachment (boom, stick and load).

The principle is straightforward: as the equipment is lowered, the gas in the cylinder is compressed, storing energy, as the equipment is lifted, the stored energy assists the lifting action, so that less force is required. This in turn enables the use of smaller hydraulic cylinders and reduced engine horsepower.

The LH 60 M and A934 HD ERC feature additional fuel savings and performance achieved with the newly developed system “Liebherr Power Efficiency” (LPE). Drawing on the characteristic performance parameters of the hydraulic components and engine, LPE electronically ensures that the performance profile is adjusted to the maximum performance efficiency; at a lower engine rpm as well as reduced fuel consumption.

These two innovations, ERC and LPE, combine to give the LH 60M and A934 HD ERC more than a 5 percent increase in production, 20 percent reduction in fuel consumption and a 2 db drop in sound levels; when compared to the previous model, according to the manufacturer.

The machine features improved service access, steps and upper railings. The new operator’s cab increases visibility and comes standard with an air suspension seat as well as air conditioning. Touchscreen display and multi-function joysticks are standard. Options include cab risers as well as a hydrauli- cally adjustable cab.
