Liebherr have released the new crawler crane LR 1100.1 for the world market
The crane is optimised for all typical lifting applications in the 100-tonne category and can be configured either with a main boom up to 62 m, or with a main boom up to 44 m in combination with a fixed jib up to 20 m.
The LR 1100.1 is fitted with a 230 kW engine to provide the necessary performance for the lifting operations and, thanks to the Eco-Silent Mode, the engine speed can be reduced to a predefined level. This means that diesel consumption and noise emission are reduced. The Automatic Engine Stop Control offers a further economic and environmentally friendly solution.
The crawler crane has been designed for quick transfer between construction sites. The transport width is 2,983 mm or 3,500 mm, depending on whether the crane is transported with or without crawlers. At the construction site, the assembly of the LR 1100.1 is simplified through the self-assembly system and radio remote control.
Radio remote control means the machine can be operated from outside the cabin, allowing for blind spots to be avoided. In addition, the cabin of the new crawler crane can be elevated by 2.8 m thus allowing for a good all-round view.
For the 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 information about the permissible and actual gradient and the crane's overall centre of gravity at all times. If necessary, the boom angle can be altered so that the machine remains in the safe area.
