Six New Unplugged Machines from Liebherr-Werk Nenzing GmbH

Liebherr-Werk Nenzing GmbH has promptly reacted to the ever-changing requirements of the construction industry with the first battery-powered drilling rig in the world – the LB 16 unplugged. Today, no less than six new unplugged products can be presented from the fields of piling, drilling and lifting.

The new piling rig from Liebherr: LRH 200 unplugged.

The Piling rigs LRH 100.1 unplugged and LRH 200 unplugged, drilling rigs LB 25 unplugged and LB 30 unplugged, crawler cranes LR 1130.1 unplugged und LR 1160.1 unplugged all have the same performance specifications as conventional machines and are available immediately.

Since the alternative drive of the LB 16 unplugged quickly established itself on the market as a Gamechanger, the design has been extended to further product areas. Today, the electrified unplugged series comprises crawler cranes as well as piling and drilling rigs.

An outstanding feature of the battery-powered unplugged units is zero emission. They do not produce any exhaust fumes and are extremely quiet. This strikes the right note especially in noise-sensitive regions and finds favour with construction site personnel and residents. Whether London, Paris or Oslo – the concept has already been successfully applied in these metropoles.

The battery is charged using a conventional jobsite electric supply. Operation can continue as normal while charging. In order to change to battery operation, you just need to pull out the plug, therefore: unplugged. Whether attached to the electric supply or not, the performance and range of application remains unchanged.

All the models are available in both conventional and battery-operated versions and have identical performance specifications.

The new Liebherr crawler crane type LR 1130.1 is available as electro-hydraulic and conventional version.

The new machines LR 1130.1 unplugged and LR 1160.1 unplugged extend the range of crawler cranes from Liebherr-Werk Nenzing GmbH.

The electro-hydraulic drive of the new cranes has the same performance specifications as the conventional version. Both versions are operated in the same way, which is especially practical if the crane driver has to often change between machines in one fleet.

The capacity of the battery is designed for an average lifting operation of eight hours. The battery can be recharged within only 2.5 to 4.5 hours. As an option, the performance can be increased by 20 to 60 per cent using additional batteries.

In idling mode, the sound pressure level of three unplugged cranes is equivalent to that of a normal conversation on the jobsite. This corresponds to a value of only 60 dB(A). If it is taken into account that a crawler crane is in idling mode for 60 % of the time on the jobsite, this low noise level is an advantage with great resonance.

The designers of the crane laid great emphasis on the safety concept. As with all crawler cranes from Liebherr-Werk Nenzing GmbH, the new battery-operated models are also available with all proven assistance systems.

The latest system 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 permissible and actual gradient, and the crane’s overall centre of gravity at all times.
