Liebherr has optimized its new LR 1100.1 crawler crane for all typical lifting applications in the 100-tonne category.

The crane may be configured either with a main boom up to 62 metres, or with a main boom up to 44 metres in combination with a fixed jib measuring up to 20 metres.

The LR 1100.1 is equipped with a 230-kW engine, providing the necessary performance for lifting operations. Thanks to the eco-silent mode, the engine speed can be reduced to a predefined level. This means diesel consumption and noise emission are reduced, without compromising performance levels.   The automatic engine stop control offers a further economic and environmentally friendly solution. After checking certain system functions, the engine is switched off during longer work interruptions.

Simple self-assembly

The crawler crane is optimized for quick transfer between construction sites. The transport width is about 3 metres or 3.5 metres, depending on whether the crane is transported with or without tracks. At the construction site, the assembly of the LR 1100.1 is simplified through radio remote control and the self-assembly system.

Radio remote control provides the operator with a high degree of flexibility and additional safety, even during operation. The Liebherr crane can be operated from outside the cab, allowing for a better overview of the construction site. This also helps to avoid possible blind spots during operation. Depending on the application, a second person is no longer required to assist with hand signals during lifting operations. As well, the cab of the new crawler crane can be elevated by 2.8 metres, allowing for an improved all-round view.

Safe on slopes

For safe negotiation of slopes and inclines, the new crane is fitted with Gradient Travel Aid. The control system automatically calculates the centre of gravity and warns the operator before the crane leaves the safe area. While travelling, the operator receives constant information about the actual grade, and the crane’s overall centre of gravity. If necessary, the boom angle can be altered so the machine remains in the safe area.
