"The year 2020 particularly proved that one must be bold and experimental in order to break new ground. With our unplugged crane we offer our customers an alternative drive design," said Gerhard Frainer, sales director of Liebherr Werk Nenzing GmbH during the online awards ceremony.  

He continued: "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.

"We were in no doubt that we would extend the concept to further product ranges and successfully establish ourselves there too. And we will continue to develop further unplugged models in the future."

The LR 1250.1 was only launched in December and is already successfully deployed on the first job site in Oslo. Further models in the unplugged series will go into operation in Great Britain during the coming weeks.

The LR 1250.1 unplugged is driven by an electric motor with a power rating of 225kW. There are no compromises regarding the performance or availability of the unplugged crane when compared with the conventional version, and it has a maximum lifting capacity of 250t.

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.

The crane can be recharged on a conventional job site electric supply (32A, 63A) in 4.5 hours and optionally with 125A in 2.25 hours. The capacity of the battery is designed for four hours of lifting operation. In accordance with its name, the crane can be operated with or without a cable, thus ‘unplugged', thanks to the battery-electric drive design.
