Liebherr has unveiled three brand-new machines for deep basis work, materials dealing with and lifting, together with the world’s first battery-powered crawler cranes. 

The LR 1200.1 unplugged and the LR 1250.1 unplugged are the world’s first battery-powered crawler cranes. Each are pushed by electrical engines with a system efficiency of 255 kW. The LR 1200.1 unplugged has a most lifting capability of 200 tonnes and the LR 1250.1 lifts 250 tonnes.

The cranes could be recharged on a traditional jobsite electrical provide in 4.5 hours or with 125 A in 2.5 hours. The capability of the battery is designed for 4 hours lifting operation. In accordance with their title, the cranes could be operated with no cable, thus “unplugged” because of the battery-electric drive design. 

“Particularly the yr 2020 has proven that one have to be open-minded and daring to interrupt new floor. With our unplugged cranes we provide our clients another drive design. As we now have already seen with the LB 16 unplugged, the primary battery-powered drilling rig, the technique is an entire success. Strict necessities relating to environmental sustainability in tenders for building initiatives enhance the demand for superior applied sciences. For us, it was clear that we lengthen and efficiently set up the design in additional product teams,” mentioned Gerhard Frainer, Managing Director for Gross sales at Liebherr.

The LRB 23 compact piling and drilling rig closes the hole between the LRB 16 and the LRB 355.
The brand new machine for deep basis work presents an engine output of 600 kW and delivers the mandatory capability for all widespread deep basis work, reminiscent of drilling with a Kelly drill, a double rotary drill, full displacement tools, a steady flight auger, in addition to soil mixing and functions with a vibrator or hydraulic hammer. 

Locking of the Kelly bar’s telescopic sections is made considerably simpler with the help of the Kelly visualization system. Because of the true time show of the Kelly bar’s locking recesses on the cabin monitor, the operator is all the time knowledgeable in regards to the precise distance to the subsequent locking recess. Color indications inform the operator of when the bar could be locked. Moreover, false positioning of the Kelly bar in the course of the shake-off course of is indicated via a warning sign.

With the model new HS 8070.1, Liebherr unveils the most recent era of obligation cycle crawler cranes. The machine has a lifting capability of 70 tonnes and is right for a large number of functions together with materials dealing with, deep basis work or lifting work. 

Utilizing the brand new self-loading system, the crawlers could be simply disassembled for transportation, decreasing the transport weight to lower than 35 tonnes.

As a substitute of a single counterweight, the machine now has a modular system. The obligation cycle crawler crane could be individually geared up relying on the appliance. The increase of the HS 8070.1 is appropriate with the HS 8100.1 permitting clients to make use of attachments on each machines.

In comparison with the fastened system, the brand new floating A-frame system ensures increased efficiency in dynamic functions. It additionally simplifies and accelerates the meeting and transportation of the machine. The user-friendly design extends to the tank neck, which is well accessible by way of a platform on the uppercarriage.
