LTM 1120-4.1 – There’s nothing more on 4!
The new LTM 1120-4.1 was first unveiled to the world at the Conexpo 2020 in Las Vegas. To match the city of superlatives, this mobile crane is extremely powerful – in fact it is the most powerful 4-axle crane on the market. The boom is the longest in this crane class and has extremely high lifting capacities when fully raised. This increases flexibility and saves transport costs, as this crane can tackle jobs which would normally require a 5-axle crane together with all the logistics work that involves. For example, the crane is ideal for erecting radio masts or tower cranes and also features time-tested technology in the form of VarioBase® and VarioBallast®.
Low gross weight with a high lifting capacity of 135 US t / 120 t.
217 ft / 66 metres long, making it the longest boom in this crane class.
For easy starting on hills with no rolling backwards.
VarioBase® support technology makes even higher lifting capacities possible, particularly over the outriggers.
Economical and flexible:
The mechanically adjustable VarioBallast® ballast system saves ballast on the one hand and enables easily access to narrow job sites on the other.

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 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 makes starting on gradients easier. Move off safely and easily without rolling backwards.
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.
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.
