At bauma 2022, Liebherr has presented the LTM 1100-5.3 under the slogan ‘the master of all roads’ as it can travel with an axle load of only 9 tonnes to offer economical mobility worldwide

The new crane formed part of the company’s All-Terrain Cranes section at its stand at bauma. It has been designed with a focus on lightweight construction to allow as much ballast as possible to be carried with a 12-tonne axle and to achieve the lowest possible axle loads by reducing ballast.

Even in countries where mobile cranes with a 12-tonne axle load are permitted on the roads, crane operators have been demanding cranes which can be driven with low axle loads and total weights by simply removing the ballast. 

When it comes to flexible axle loads, the LTM 1100-5.3 sets new standards. With 0.8 tonnes of ballast, it reaches a total weight of 44 tonnes with axle loads of 9 tonnes. With 4.4 tonnes of ballast, it can travel with 10 tonnes of axle load and a total weight of 48 tonnes. With an axle load of 12 tonnes, the new 100-tonne crane can carry up to 16.9 tonnes of counterweights. At 75% of the maximum ballast of 22.5 tonnes, this is a new record for mobile cranes worldwide. 

This allows the new LTM 1100-5.3 to perform the majority of its jobs as a taxi crane without additional ballast transport. Even with maximum ballast, the axle loads of 13.4 tonnes are low and evenly distributed across all axles. The new LTM 1100-5.3 also boasts a narrow width of 2.55 metres – an additional advantage when driving on roads and construction sites.

At 62 metres, the telescopic boom is two metres longer than the next most powerful Liebherr 5-axle machine, the LTM 1110-5.2. In addition, a 9.5 to 16-metre folding jib is available which, as an option, can also be adjusted hydraulically between 0° and 40°. This enables the LTM 1100-5.3 to achieve hoisting heights of up to 76 metres and radii of up to 64 metres. Other options include a 2-metre assembly jib and a side-folding rooster sheave, which offer additional flexibility in use.

An innovative DynamicPerform coupling module is installed in the LTM 1100-5.3 to ensure virtually wear-free starting and manoeuvring without overheating for the modular ZF TraXon gear unit, because it transmits the engine output via an oil-cooled clutch plate pack. 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. Crane operators thus benefit from greater efficiency and lower maintenance costs.

The crane boasts a new driver’s cabin and crane cab, new paintwork and the LICCON3 control system. The third generation of the LICCON system includes a new software package and programming language as well as a faster databus, more storage space and computing powers. It enables operators to work with greater ease and be more comfortable in control. Operator comfort is also ensured with the new multifunction steering wheel, side roller blind on the driver’s door, improved instruments and modules, as well as new displays for the driver’s cabin. Modern additions such as automotive heating and air-conditioning systems contribute to a pleasant operating experience as well.
