The LTM 1100-5.3 mobile crane from Liebherr offers high mobility worldwide. Equipped with a 62-m telescopic boom, this model features lightweight construction to allow as much ballast as possible to be carried with a 12-t axle load; and to achieve the lowest possible axle loads by reducing ballast.
With 0.8 t of ballast, the LTM 1100-5.3 reaches a total weight of 44 t with axle loads of 9 t. With 4.4 t of ballast, it can travel with 10 t of axle load and a total weight of 48 t. With an axle load of 12 t, the crane can carry up to 16.9 t of counterweights.
The LTM 1100-5.3 can perform the majority of its jobs as a taxi crane without additional ballast transport. Even with maximum ballast, the axle loads of 13.4 t are low and evenly distributed across all axles. The crane has a narrow width of 2.55 m – another advantage when driving on roads and construction sites.
At 62 m, the telescopic boom is 2 m longer than the next most powerful Liebherr five-axle machine, the LTM 1110-5.2. In addition, a 9.5- to 16-m folding jib is available which, as an option, can be adjusted hydraulically between 0° and 40°. This enables the LTM 1100-5.3 to achieve hoisting heights of up to 76 m and radii of up to 64 m. Other options include a 2-m assembly jib and a side-folding rooster sheave, giving further flexibility.
The 100-t crane offers extra safety, flexibility and lifting capacity thanks to the VarioBase variable outrigger. Greater flexibility on the construction site is also provided by the standard VarioBallast, which allows the ballast radius to be adjusted between 4 and 5.1 m.
The third generation of the LICCON (Liebherr computed control) system relies on control features, but also integrates a completely new software package and programming language as well as a faster databus, significantly more storage space and more computing power. Crane operators who are familiar with the previous control system can easily use the newer version, as the recognition value is very high.
Moreover, the LTM 1100-5.3 has a modern, automatic heating and air-conditioning system in the driver’s cabin and in the crane cab to ensure a high level of comfort. A sun sensor detects strong sunshine and automatically adjusts the heating settings.
The lighting packages for the crane cab, the superstructure, the rear of the vehicle, the front headlights and the telescopic boom as well as the lattice fly jib have been optimised and can be operated with LEDs. The benefits of LED technology include a longer service life and superior lighting performance.
The DynamicPerform coupling module is also installed in the LTM 1100-5.3. It ensures 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 LTM 1100-5.3 mobile crane was recently showcased to the media during the Liebherr international trade press tour 2024, which took place in late October in Germany.
