The new Liebherr LR 1100.1 crawler crane is designed for lifting applications in the 100-t category. The machine 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 powered by a 230 kW engine. 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, without compromising the machine performance. The Automatic Engine Stop Control offers a further economic and environment-friendly solution. After checking certain system functions, the engine is switched off during longer work interruptions.
To enable easy relocation between jobsites, the LR 1100.1 has a transport width of 2,983 mm or 3,500 mm, depending on whether it is transported with or without crawlers. The assembly of the crane is simplified through the self-assembly system and radio remote control.
The radio remote control gives the operator a high degree of flexibility and additional safety even during operation. The crane can be operated from outside the cabin, providing a better overview of the jobsite. Depending on the application, a second person is no longer required to assist with hand signals during lifting operations. The cabin can be elevated by 2.8 m to allow for a good all-round view.
For the safe negotiation of slopes and inclines, the LR 1100.1 is fitted with Gradient Travel Aid [Watch the video below]. This 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.
