Design

The colour compositions combine the classic Liebherr yellow with new black, grey and white accents. The design reflects how long-standing tradition and company values unite with advanced technologies. The colour scheme lends the machines a distinctive look and immediate recognition.

The new design focuses on an even higher level of safety emphasized, above all, by improved platforms and railings on the uppercarriage. 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 how the overall concept fits harmoniously together: reduced noise, panoramic view and operator comfort. This is achieved through a modern air-conditioning system with improved airflow, an optimized field of vision and an orthopedic operator’s seat with integrated heating and cooling. Additional safety is provided by the stone protection, even in the toughest of applications.

Specifications

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, symbolizes 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 low noise level. That is a huge advantage in areas sensitive to noise and also for the people working on the job site.

 

The cranes can be recharged on a conventional job site 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 4 hours of lifting operation. In accordance with their name, the cranes can be operated without a cable, thus “unplugged” thanks to the battery-electric drive design. Gerhard Frainer, Managing Director for Sales at Liebherr-Werk Nenzing GmbH, says:

“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.”
