Liebherr is presenting the PR 724 and PR 734 Litronic from its crawler tractor range at this year’s ‘Bauma’. Both machines are from the fourth generation of crawler tractors presented last year, and are noted for their lower operating costs and excellent ride comfort. The entire driveline of these crawler tractors has been fundamentally redesigned, but retains the well-proven hydrostatic principle.
Two new Series “B” crawler loaders – the LR 622 B Litronic and the LR 632 B Litronic – are also on show in Munich. The heart of this new range is the completely revised Litronic system. The new machines also benefit in particular from a new steering system that is even more accurate and quicker and, if the travel control is advanced fully, activates the con-tra-rotating track function.
