LTM 1230-5.1 Mobile crane

The LTM 1230-5.1 delivers an extremely long telescopic boom and sets new standards in terms of lifting capacity. In addition to a multi-functional folding jib, a 43 m fixed jib is also available. The Liebherr innovations VarioBase®, VarioBallast, ECOmode and ECOdrive mean that crane operators can use the new LTM 1230-5.1 with even more safety and efficiency.

Technology

VarioBase® Plus

VarioBase® Plus

The combination of VarioBase technology and the crane’s structural steelwork. A trapezoidal support combined with the various support base delivers even higher lifting capacities, particularly over the crane’s rear outriggers.

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.
