Crawler Tractors and Sidebooms: Liebherr PR764
The PR764 Litronic crawler dozer delivers maximum pushing power and ripping force in all speed ranges regardless of the surface.
It has an operating weight of up to 52.5 tons and features a D9508 422-hp Liebherr V8 diesel engine that drives the crawler by means of four variable displacement pumps and engines, each in a closed circuit.
The operator’s cab is ergonomically designed to provide maximum comfort and safety. Air conditioning is a standard feature. Angled outer edges offer the operator an unobstructed panoramic view of the entire work area and great visibility of the blade and rear ripper.
A hydrostatic driveline system 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. 757.245.5251, www.liebherr.com
