LTM 1250-5.1 Mobile crane

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.

Technology

VarioBase®

VarioBase®

VarioBase makes the crane’s support system variable. It enables each outrigger to be extended to a different length. This enhances safety – particularly in constricted spaces. And what's more, the crane’s lifting capacities are significantly increased, particularly over the outriggers and depending on the configuration.

ECOdrive

ECOdrive

ECOdrive makes the mobile crane significantly more comfortable and quieter by reducing the engine speed. Faster gearshifting delivers greater dynamic and traction offroad. On the road, the torque from the Liebherr diesel engine is used efficiently to minimise fuel consumption.

Single-engine concept

Single-engine concept

Take one engine out to increase lifting capacity. Or more accurately – the superstructure is powered by the undercarriage engine. Gear shafts are routed from the distributor gear in the substructure via two mitre gears to the pump distributor gear in the superstructure. That enables us to remove one engine – and we use this to increase the crane’s lifting capacity.

ECOmode

ECOmode

ECOmode minimises both fuel consumption and noise emissions when operating the crane superstructure. The crane operator sets the required working speed using the control lever. The LICCON 2 control system calculates the perfect engine speed for the diesel engine.

VarioBallast® (mechanical)

VarioBallast® (mechanical)

Mechanically slewing ballasting cylinders enable the ballast radius to be changed quickly to two different settings. The smaller radius is used in constricted conditions whilst the larger one is used if a higher lifting capacity is required. This significantly increases the crane’s flexibility.

The crane cabin on this crane can be telescoped into the air with infinite adjustment. The better view from above of the load and working environment significantly increases safety during crane operations – and driver comfort is also massively enhanced.
