Liebherr launches the world’s first battery-powered crawler crane

The LR 1200.1 unplugged and the LR 1250.1 unplugged are one of the world’s first battery-powered crawler cranes. Both are driven by electric engines with a system performance of 255 kW.

There are no compromises regarding performance or availability when compared with the conventional versions. The LR 1200.1 unplugged has a maximum lifting capacity of 200 tonnes and the LR 1250.1 lifts 250 tonnes.

The blue accent in the colour composition, which lends the distinctive look to the unplugged series, symbolises the electric solution representing an advanced technology. The unplugged cranes achieve the best possible combination of operator benefit, efficiency and environmental sustainability.

Thanks to Zero Emission the new machines are emission free and have a very low noise level. That is a huge advantage in areas sensitive to noise and also for the people working on the jobsite.

The cranes can be recharged on a conventional jobsite electric supply (32 A, 63 A) in 4.5 hours and optionally with 125 A in 2.25 hours. The capacity of the battery is designed for four hours lifting operation. In accordance with their name, the cranes can be operated without a cable, thus “unplugged” thanks to the battery-electric drive design.

“Especially the year 2020 has shown that one must be open-minded and bold to break new ground. With our unplugged cranes we offer our customers an alternative drive design. As we have already seen with the LB 16 unplugged, the first battery-powered drilling rig, the strategy is a complete success. Strict requirements regarding environmental sustainability in tenders for construction projects increase the demand for advanced technologies. For us, it was clear that we extend and successfully establish the design in further product groups,” says Gerhard Frainer, Managing Director for Sales at Liebherr-Werk Nenzing GmbH.
