The firm says that the machine's electro-hydraulic drive has the same performance specifications as the conventional diesel version. Both versions are operated in the same way, which is convenient for operators if they have to switch between machines.

In addition to offering zero emissions, the unplugged crane models are also extremely quiet in operation, which is important for use in noise-sensitive areas such as urban locations.

The LR 1160.1 unplugged can be operated with or without cable, therefore unplugged. Capacity of the battery is designed for 8 hours lifting operation. The crane can be operated while plugged into a conventional electric supply with 63A, or charged within 4.5 hours. Using a 125A supply, the battery can be fast-charged in only 2.5 hours.

The LR 1160.1 unplugged is equipped with Liebherr’s proven safety systems. The latest feature of the LR 1160.1 unplugged is the Gradient Travel Aid for the safe negotiation of slopes and inclines. The control system calculates the centre of gravity and warns the operator before the crane leaves the safe area. While travelling, the operator receives information about gradient and the crane's overall centre of gravity. If necessary, the boom angle can be altered.
