Liebherr LTM 1110-5.1

Innovative Design and Capacity

The LTM 1110-5.1 represents a breakthrough in crane design, combining lightweight engineering with robust performance. It offers a gross weight under 48 tonnes, achieving an axle load of less than 10 tonnes, which facilitates easier road licensing and route approval. The crane’s design allows it to carry up to 13.1 tonnes of counterweight while staying within a 12-tonne per axle limit, reducing the need for additional ballast transport and thus lowering operational costs.

Telescopic Boom and Extensions

With one of the longest telescopic booms in its class at 60 meters, coupled with a folding jib that extends from 10.8 to 19 meters and can be adjusted between 0° to 40°, the LTM 1110-5.1 pushes the boundaries of lifting capabilities. Optional lattice sections further extend the boom, achieving maximum hook heights comparable to larger models like the LTM 1130-5.1.

Advanced Mobility and Flexibility

The crane features the VarioBasePlus system, which provides extended rear supports that widen up to 8.3 meters for enhanced capacity over the rear. This system allows for a trapezoidal and variable support base, increasing stability and enabling the crane to operate efficiently in confined spaces.

Powerful Engine and Transmission

A six-cylinder Liebherr diesel engine delivering 400 kW (544 bhp) and 2,516 Nm of torque powers the crane, adhering to the latest emission standards including Stage V. The innovative ZF-TraXon gearbox, with its DynamicPerform version, offers smoother start and maneuver capabilities, akin to those provided by a torque converter.

Eco-Friendly Operations

Liebherr’s commitment to sustainability is evident in the LTM 1110-5.1’s integration of ECOmode, which optimizes fuel consumption and reduces noise emissions during operations. The mode includes an automatic pump drive disconnect that re-engages when necessary, and a smart engine speed calculation that matches the optimal speed to the required work pace, potentially reducing fuel usage by up to 10%.
