Updated Liebherr mobile crane features new control system, driver's cab and gearbox

The Liebherr LTM 1110-5.1 mobile crane has been updated and is now the LTM 1110 5.2. The updated machine contains three completely new features - the new LICCON3 crane control system, the driver's cab and the ZF TraXon DynamicPerform gearbox.

LICCON3 crane control system

The third generation of the LICCON (Liebherr Computed Control) control system features a completely new software package and programming language as well as a faster databus, significantly more storage space and more computing power.

Components, such as the BTT remote control terminal, have been included. The touchscreen function on the new large display in the superstructure cab means that it is now even easier and more comfortable to control. LICCON3 cranes are also prepared for telemetry and fleet management systems as standard. In the future, crane contractors will be able to view and evaluate all the relevant data using the MyLiebherr customer portal.

Driver's cab with award-winning design

Liebherr has developed the design of the new driver's cab in collaboration with designer Jürgen R. Schmid. The cab was awarded the American GOOD DESIGN award 2020, an award for the most innovative and modern industry, product and graphic designs from all over the world.

Design features include a new multifunction steering wheel, a side roller blind on the driver's door, improved instruments and modules as well as new displays. Options, such as the central locking system with remote key, the cool box and tire pressure monitoring system deliver additional comfort.

A completely new, automatic heating and climate control system in both the driver's and operator's cabs guarantees comfortable working conditions. A sun sensor detects strong sunshine and automatically adjusts the heating settings. 

ZF TraXon DynamicPerform gearbox

The DynamicPerform clutch module delivers almost zero wear when starting and manoeuvring for the modular ZF TraXon gearbox. The new clutch module transmits the engine power via an oil-cooled plate pack that runs in oil. The friction heat generated when starting is dissipated in the clutch oil and supplied to the vehicle's cooling system via an oil/water heat exchanger.

Due to the higher energy and power consumption, together with a calculation model, permanent and almost wear-free manoeuvring is made possible. An implemented clutch protection function also prevents overheating of the clutch and the associated increased wear or destruction of the clutch in extreme load cases. 

Initially, Liebherr plans to install DynamicPerform in its 5-axle mobile cranes on a step-by-step basis. On mobile cranes with six or more axles, Liebherr intends to continue to use the ZF 12-speed TraXon Torque gearbox with starting converter, which in addition to zero-wear manoeuvring, also delivers an increase in torque.
