The new LR 1160.1 unplugged from Liebherr is one of the world’s first battery-operated crawler cranes.

The electro-hydraulic drive has the same performance specifications as the conventional version. Both versions are operated in the same way, which is convenient for crane operators if they switch between machines.

Liebherr’s unplugged machines produce zero emissions and are extremely quiet.

In idling mode, the sound pressure level of three unplugged cranes at 16 metres is the equivalent to that of a normal conversation on the jobsite at a distance of 1 metre. This equals about 60 dB(A) of sound generated.


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

Safe operation

Liebherr’s crane designers placed emphasis on safety when creating the LR 1160.1 unplugged. Just like every crawler crane from Liebherr-Werk Nenzing GmbH, the LR 1160.1 unplugged is equipped with all established assistant systems for safe operation.

The latest feature of the LR 1160.1 unplugged is the Gradient Travel Aid for the safe negotiation of slopes and inclines. The crane’s 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 crane’s overall centre of gravity. If necessary, the boom angle can be altered so the machine remains in the safe area.

Ground Pressure Visualization calculates the actual ground pressure of the machine in real time and compares it with the specified safety limits of the relevant jobsite. This means the operator is permanently aware of whether the machine is situated in, or is approaching, a critical area.

When erecting or lowering the boom, the Boom Up-and-Down Assistant indicates the approach to the tipping border and automatically stops operation before the operator unintentionally enters an unsafe zone.

The first LR 1160.1 unplugged head to Great Britain

Liebherr-Werk Nenzing GmbH delivered the first three LR 1160.1 unplugged cranes to Great Britain. Select Plant Hire Company Ltd. is pursuing the goal of operating more and more zero-emission construction sites and has even planned three further LR 1160.1 unplugged cranes as investment for 2022.

Select already put its trust in the LR 1250.1 unplugged, the world’s first battery-powered crawler crane, at the time of its market launch.
