The new 750-ton mobile crane is designed to complement the Liebherr range of self-propelled cranes, taking its place between successful models 1500-8.1 & 11200-9.1.

A distinctive feature of the new 9-axle crane is the possibility of traveling on public roads. For more economical operation around the world, LTM 1750-9.1 has taken into account the requirements for different transport weights and axle loads. Structurally, the new mobile crane is designed for maximum operational installation in the working position.

Due to its high load capacity of 750 tons, the crane is able to single-handedly lift, for example, a tunneling machine. Previously, it was necessary to use two cranes working in tandem. With a telescopic boom of 52 m long, Y-braking and various latticed extensions, the crane operator has a variety of boom systems that provide a lifting height of 154 m and a reach up to 112 m.

The telescopic boom is 52 m long, the Y-hauler and a variety of trellis extenders provide a lifting height of up to 154 m and a reach of up to 112 m.

The grille extension with variable outreach can be increased to 91 m by intermediate sections of 3.5 m. The slope of the fixed grille extension up to 62 m in length can optionally be hydraulically operated. Thus, the position of the extension cord can be changed even under the load. A special auxiliary extension cable with a carrying capacity of 56 tons is also available. It is mounted both on a telescopic boom and on a stationary trellis extension or swinging lattice.
