Liebherr unveiled a new 250-tonne mobile crane at its 2015 customer days at the manufacturing plant in Ehingen. The LTM 1250-5.1 is now the most powerful mobile crane on five axles on the market. It is the third crane model on which Liebherr uses its innovative single-engine concept. In addition to a multi-functional folding jib, a 50 m fixed jib is also available. The Liebherr innovations VarioBase? and ECOmode mean that crane operators can use the new LTM 1250-5.1 with even more safety and efficiency.

The LTM 1250-5.1 is the successor to the globally successful LTM 1220-5.2. In the development of the new crane, Liebherr followed the concept of achieving maximum load capacity from the available weight of a 5-axle mobile crane. The result is that the LTM 1250-5.1 is now the most powerful crane in this class in the world. Its load capacity has been increased compared to its predecessor by around 15-20 per cent whilst the telescopic boom has remained at the same length of 60 m. With lattice extensions the maximum hook height has been increased by a massive 9 m to 110 m.

Liebherr has a particularly wide and variable range of lattice jibs for the new LTM 1250-5.1. The 12.2 m to 22 m folding jib can be extended to up to 36 m with 7-m sections. The folding jib is attached with a 0?, 22.5? or 45? inclination. The folding jib can be supplied with a hydraulic adjustment system as an option which allows it to luff with a full load between 0?and 45?. The adapter section for the folding jib is used as a 5.4 m erection jib. The pivot point for the folding jib can be raised using up to two straight 7 m lattice sections acting as telescopic boom extensions. These sections and the folding jib extensions can also be used on the Liebherr LTM 1200-5.1 and LTM 1220-5.2 mobile cranes. This is a major benefit for crane operators that use these crane models in their fleet.
