Liebherr’s new LR 1100.1 crawler crane
Liebherr has launched its new LR 1100.1 crawler crane, optimised for all typical lifting applications in the 100-tonne category.
It 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 230 kW engine and can be used in Eco-Silent Mode. The engine speed can be reduced to a predefined level, reducing diesel consumption and noise emissions. The Automatic Engine Stop Control allows the engine to switch off during longer work interruptions.
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.
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.
