Liebherr Unveils the World's First Battery-Powered Crawler Cranes
Dec. 9, 2020 - Liebherr’s Nenzing group recently unveiled the world’s first battery-powered crawler cranes, the 275-USt capacity LR 1250.1 unplugged and the 242-USt capacity LR 1200.1 unplugged.
Each model is driven by a 255kW (342-hp) electric engine, and both make no compromise in performance or availability, compared with their conventional, diesel-powered, versions.
The LR 1200.1 unplugged has a maximum lifting capacity of 242 USt, and the LR 1250.1 lifts 275 USt.
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.
Both new cranes produce no emissions and have a low noise level. That’s a big 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 (32A or 63A) in 4.5 hours and optionally with 125A in 2.25 hours. The battery is designed for 4 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,” said Gerhard Frainer, managing director of sales at Liebherr-Werk Nenzing GmbH. “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.”
The new design focuses on an even higher level of safety emphasised, above all, by improved platforms and railings on the upperworks. Thanks to the additional add-on wing for mounting lights or cameras, the design is more flexible on the whole.
Inside the new cabin, the operator experiences immediately how the overall concept fits harmoniously together: reduced noise, panoramic view, and pure operator comfort. This is achieved through a modern air-conditioning system with improved airflow, an optimized field of vision, and an orthopaedic operator’s seat with integrated heating and cooling.
