Liebherr-Werk Ehingen in Germany is developing a crawler-mounted version of its 1,200 tonne capacity telescopic wheeled mobile crane.

A typical application for the LTR 11200 will be in wind turbine parks. Initial concepts considered the possibility of the crane being able to switch between wheels and crawler tracks (see picture) but this will not happen on the final design. Several units have been ordered and deliveries will start next year, a Liebherr spokesman told IC.

The boom and upper works will be from the record-breaking 1,200 tonne capacity LTM 11200-9.1 telescopic wheeled mobile crane first seen in the iron early in 2007. The crawlers will be from the 350 tonne capacity LR 1350/1 lattice boom crawler crane.

This model follows in the wake of, most recently, the 100 tonne capacity LTR 1100 telescopic crawler crane.

Prior to that Liebherr’s first telescopic crawler was the so-far one-off 800 tonne capacity LTR 1800. This crane used the telescopic boom upper works from the LTM 1800 telescopic wheeled mobile and the crawlers from the LR 1550. It is working in Asia.
