The LTM 1250-5.1 features enormous load capacities. VarioBallast enables the crane to deliver maximum load capacities with a large ballast radius, making it perfect for use on constricted sites with a small ballast radius. The crane can be fitted with a multi-functional folding jib or a long fixed jib. The Liebherr innovations VarioBase® and ECOmode make the LTM 1250-5.1 particularly safe and efficient.

Liebherr has a particularly wide and variable range of lattice jibs for the new LTM 1250-5.1:
- Folding jib up to 36 m
- Erection jib 5.4 m
- Telescopic boom extension 14 m
- Strong jib 46 m
- Fixed jib 50 m, hydraulically adjustable between 0° and 45°
- Maximum hoisting height 108 m
The LTM 1250-5.1 can be operated with two different ballast radii: 5.58 m or 4.78 m
Liebherr has designed a solution to adjust the ballast radius particularly quickly and easily. The ballast radius is reduced by 800 mm using standard mechanically adjusted ballasting cylinders. This solution is a major benefit of the new 250-tonne model for use in constricted conditions.
Innovative Single-Engine Concept
The new Liebherr single-engine concept is once again used on the LTM 1250-5.1, with the superstructure being powered by a mechanical shaft. Gear shafts are routed from the distributor gear in the substructure via two mitre gears through the centre of the slewing ring to the pump distributor gear in the superstructure.
The add-on program ECOmode allows the mobile crane to be run particularly efficiency.
