Mobile crane
Maximum performance on four axles, that is the concept of the LTM 1120-4.2, the most powerful 4-axle crane on the market.
The third generation of the LICCON control system takes the familiar crane control to a new level and features some impressive new technologies.
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.
VarioBase® support technology makes even higher lifting capacities possible, particularly over the outriggers.
The mechanically adjustable VarioBallast® ballast system saves ballast on the one hand and enables easily access to narrow job sites on the other.
The new DynamicPerform clutch module on the TraXon gearbox transmits engine power via integrated disks that are cooled by oil circulation.
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.
The RemoteDrive remote control enables the crane to be controlled from outside the driver’s cabin. This is not only possible during crane operations, but also whilst driving on the site. This delivers greater safety and comfort as the crane operator has a better view of problem areas as he can be right next to them. In other words, the operator can move himself to the areas with difficult access.
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 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.
The AutoBallast function completes the ballasting process automatically. All the steps are carried out after the button has been pressed just once.
Increased flexibility and safety by using lifting capacity tables with different maximum wind speeds.
Up to 90 % lower CO2 emissions in action.
Driver assistance systems for extra safety on the road. All new mobile crane models are equipped with driver assistance systems that support the crane driver with additional „eyes“. They scan the environment and warn the crane driver to prevent accidents.
