LTM 1090-4.2 Mobile crane

The mobile crane LTM 1090-4.2 combines mobility, performance and economy at the highest level. It is worldwide economically mobile, because it can be driven with 10 tons, 12 tons and 16 tons axle load. With its ECOdrive and ECOmode the LTM 1090-4.2 is operated extremely environmental friendly, low on consumption and with low noise. The Liebherr innovations VarioBallast and VarioBase® cater for more performance, flexibility and safety.

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.

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.
