The Liebherr LTM 1110-5.1 mobile crane is now the LTM 1110-5.2, thanks to the addition of several new features.

Liebherr has upgraded the 110-tonne mobile crane with a new crane control system, cab, gearbox and an oil-cooled multi-disk clutch.

To go with these new features, Liebherr has unveiled a completely new standard crane design, which marks the future for its all-terrain series.

LICCON3 crane control system

The LTM 1110-5.2 includes the third generation of the LICCON (Liebherr Computed Control) control system that features a new software package and programming language as well as a faster data bus, significantly more storage space and more computing power.


“During the development of the new control system, it was important to us that crane operators, who are familiar with Liebherr cranes, would be able to get used to the new control system quickly and easily,” said Nikolaus Münch, head of the Control System Department at Liebherr

“At the same time, we must be future-proof as the progress currently being made in microelectronics is immense. Complex applications, such as VarioBase®, which require a great deal of performance data, can now be developed more frequently in the future. The current LICCON2 control system is reaching the limits of its capacity.”

Time-tested hardware components, such as the BTT remote control terminal, have been included. The touchscreen function on the new display in the superstructure cab means it is now easier and more comfortable to control. The way in which the information is shown has also been revised and simplified.

Award-winning cab

Liebherr’s new cab was created in collaboration with designer Jürgen R. Schmid, Design Tech. It was awarded the Good Design award 2020 in the Transportation category, presented by the Chicago Atheaeum Museum of Architecture and Design.

Due to high synergy effects, Liebherr is introducing the new cab at the same time as the LICCON3 control system. The modern design features premium materials and timeless lines as well as delivering a whole host of improvements for the crane operator. These include the new multifunction steering wheel, 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 tyre pressure monitoring system deliver additional comfort.

A completely new, modern automatic heating and climate control system in both the driver’s and operator’s cabs guarantee comfortable working conditions. A sun sensor detects strong sunshine and automatically adjusts the heating settings. In addition to the standard radio with hands-free facility, a double DIN radio with extended functions is available as an option.

ZF TraXon DynamicPerform gearbox

The innovative DynamicPerform clutch module delivers almost zero wear starting and manoeuvring for the modular ZF TraXon gearbox without overheating. 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.

Liebherr was ZF’s partner in the development of the TraXon DynamicPerform and its integration in the drivetrain of mobile cranes.

“As a result of the close collaboration with ZF and a very intensive phase of testing, the new gearbox version is now ready for widespread use. The cooling performance of the DynamicPerform clutch module has been significantly increased yet again by means of improvements to various hardware components,” said Josef Schick, head of the Testing Department at Liebherr.

“The model has also been refined for calculating the disc temperature. Vehicle tests in a refrigeration chamber at temperatures as low as minus 40 degrees have confirmed that DynamicPerform works very well even in extremely low temperatures. We have managed to solve all the initial problems. Overall, we can safely say that there are worlds of differential between a dry clutch and the new wet starting clutch.”
