Liebherr Adds to Crawler Line

Liebherr introduces its new hydrostatically-driven crawler, the PR 764 Litronic.

 Liebherr Construction Equipment Co., Newport News, Va., has stepped up its crawler range a notch by introducing the new PR 764 Litronic. This features a new revolutionary drive concept: the D9508 310kW / 422-horsepower Liebherr V8 diesel engine, which drives the crawler by means of four variable displacement pumps and engines, each in a closed circuit.

 

The PR 764 Litronic has a completely redesigned operator’s cab, which is ergonomically designed to provide maximum comfort and safety, the company says.  The cab’s distinctive angled outer edges offer the operator an unobstructed panoramic view of the entire work area and great visibility of the blade and rear ripper.

 

Easily accessible maintenance hoods, a fuel tank filling point on the side, a standard tilt cab and the centrally-posi­tioned maintenance modules make the PR 764 Litronic easy to maintain and also ensure safe operation, the company says.

 

The PR 764 Litronic features a hydrostatic driveline system that provides increased pushing power, tractive force and counter-rotation. The hydrostatic drive has a particularly low center of gravity, which makes the machine safe to operate even on very steep slopes, the company says.

 

Available as an option; a pivoting track system enables the rollers to adapt to the ground conditions. This ensures the engine’s pulling power even in the toughest ground conditions.
