Liebherr LR 1250.1 unplugged
Liebherr has unveiled what it claims are the world's first battery-powered crawler cranes, the LR 1200.1 unplugged and the LR 1250.1 unplugged.
Both are driven by electric engines with a system performance of 255 kW.
The LR 1200.1 unplugged has a maximum lifting capacity of 200 T, and the LR 1250.1 lifts 250 T.
The new machines are emission-free and have a very low noise level.
"With our unplugged cranes, we offer our customers an alternative drive design," says Gerhard Frainer, managing director for sales at Liebherr-Werk Nenzing. "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."
Liebherr's virtual launch also included a new HS 8070.1 crawler crane. The machine has a lifting capacity of 70 T and uses a new self-loading system (Jack-Up System) which allows the crawler to be easily disassembled for transportation, so reducing the transport weight to less than 35 T.
