Mobile Crane LTM 1250-5.1
The Liebherr mobile crane LTM 1250-5.1, which is on display in Delhi is the most powerful mobile crane on 5 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 50m 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 global success model 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 the most powerful crane in its class in the world. Its load capacity has been increased compared to its predecessor by around 15% - 20% whilst the telescopic boom has remained at the same length of 60m. With lattice extensions the maximum hook height has been increased by a massive 9m to 110m.
VarioBallast is a new feature for Liebherr. The LTM 1250-5.1 can be operated with two different ballast radii: 5.58m or 4.78m. Liebherr has designed a solution to adjust the ballast radius particularly quickly and easily. The ballast radius is reduced by 800mm using standard mechanically swivelling ballasting cylinders. This solution is a major benefit of the new 250-tonne model for use in constricted conditions.
