Mobile crane

LTM 1120-4.2 – There’s nothing more on 4!

Maximum performance on four axles, that is the concept of the LTM 1120-4.2, the most powerful 4-axle crane on the market. Its 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. The crane is e.g. ideal for erecting radio masts or tower cranes and is also equipped with proven technology in the form of VarioBase® and VarioBallast®.

  • Max. load capacity - 120 t

  • Telescopic boom - 66 m

  • Max. hoist height - 91 m

  • Max. radius - 64 m

  • Number of axles - 4

What's inside

LICCON3:

The third generation of the LICCON control system takes the familiar crane control to a new level and features some impressive new technologies.

Powerful:

Low gross weight with a high lifting capacity of 135 US t / 120 t.

Telescopic boom:

217 ft / 66 metres long, making it the longest boom in this crane class.

Variable support:

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.

Wear-free manoeuvring:

The new DynamicPerform clutch module on the TraXon gearbox transmits engine power via integrated disks that are cooled by oil circulation.

Technology

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.
LICCON3
The third generation LICCON control system features the same time-tested operation as previous generations and adds a fast data bus, significantly more storage space and greater computing power. LICCON3 cranes are prepared for telematics and fleet management.
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.
