립헬, 세계 최초 배터리 구동 전기크레인 발표 VIDEO: Liebherr Premieres the World’s First Battery Powered Crawler Cranes


Liebherr Premieres the World’s First Battery Powered Crawler Cranes

January 20, 2021 Shane Hedmond


As more and more battery powered heavy construction equipment is being released to help lower noise and emissions on the jobsite, I shouldn’t be that surprised to hear about a battery powered crawler crane – but, I still am.




세계 최초 배터리 구동 크레인


275톤까지 리프팅


   점점 더 많은 배터리 구동 건설 장비들이 작업 현장에서 소음과 배출량을 낮추기 위해 출시되고 있기 때문에, 배터리 구동 크레인 이야기를 듣는 것은 그다지 놀랄 일이 아니다.




12월, 크레인 제작업체인 립헬(Liebherr)은 세계 최초의 배터리 구동 크레인을 공개했다. 이 소형 크레인은 275톤까지 들어올릴 수 있다.


표준 버전으로 모델링된 LR 1200.1 언플러그드 및 LR 1250.1 언플러그드를 발표하였다. 1200은 둘 중 더 작은 것으로 최대 양력 220톤(200 미터 톤)이며, 1250은 275톤(250 미터 톤)까지 양력이 가능하다

In December, crane manufacturer – and amazingly cool crane video maker – Liebherr unveiled what they are calling the world’s first battery powered crawler cranes.  These aren’t some dinky little mini-cranes either, they can lift up to 275 tons (250 metric tonnes). 




Modeled off of their standard versions, Liebherr announced the LR 1200.1 unplugged and the LR 1250.1 unplugged. The 1200 is the smaller of the two, with a maximum lift capacity of 220 tons (200 metric tonnes) and the 1250 can lift up to 275 tons (250 metric tonnes).

The company says that the electric versions do not sacrifice any performance versus their conventional counterparts. With the machine plugged in, operators will see unlimited runtime, but with it unplugged, operators can expect up to 4 hours of runtime. 


On conventional power, the batter will take about 4.5 hours to charge, while a higher amperage fast charging setup with fully charge the battery 2.25 hours.


According to the LR 1250.1 Unplugged’s data sheet, sound levels inside the cab peak at 72 dB, whereas sound levels outside of the machine will peak at 105 dB. The non-electric version of the LR 1250.1 states 72.9 dB and 107 dB, respectively.



Presumably due to the weight of the battery, the unplugged version also adds a little over 2 tons to the overall weight. The new machines also produce zero emissions, which can be helpful on sensitive jobsites. 




“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, in a press release.
