Outstanding mobility, power and economy. These are the main features of the LTM 1090-4.2. It can be driven all over the world at low cost as it can be configured with a whole series of different axle loads for driving on roads and sites. ECOdrive and ECOmode reduce its fuel consumption and noise emissions – better for drivers and the environment! Our Liebherr VarioBallast® and VarioBase® innovations enhance its capacity, safety and flexibility.

    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 crane control system calculates the perfect engine speed for the diesel engine.
    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.
    Hillstart-Aid
    Hillstart-Aid makes starting on gradients easier. Move off safely and easily without rolling backwards.
    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.
    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.
    AutoBallast
    The AutoBallast function completes the ballasting process automatically. All the steps are carried out after the button has been pressed just once.
