Liebherr has launched three deep foundation, material handling and lifting brand-new tools, including the world’s first battery-powered crawler cranes.
Lifting
The LR 1200.1 unplugged and the LR 1250.1 unplugged are the world’s first battery-powered crawler cranes.
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 tonnes, and the LR 1250.1 lifts 250 tonnes.
The cranes can be recharged on a conventional Jobsite electrical power in 4.5 hours or 125 A in 2.5 hours.
The battery capacity is designed for four hours of lifting operation.
By their name, the cranes can be worked 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.
As we’ve seen with the LB 16 unplugged, the first battery-powered drilling rig, the strategy is a total success.
Strict requirements for environmental sustainability in tenders for construction projects increase the demand for innovative technologies.
For us, it was clear that we extend and successfully establish the design in further product groups,” said Gerhard Frainer, Managing Director for Sales at Liebherr.
Deep foundation work
The LRB 23 compact piling and drilling rig close the gap, between the LRB 16 and the LRB 355.
The new machine for deep foundation work offers an engine output of 600 kW.
It delivers the necessary capacity for all common deep foundation work, such as drilling with a Kelly drill, full displacement equipment, a double rotary drill, a continuous flight auger, and soil mixing and applications with a vibrator hydraulic hammer.
The locking of the Kelly bar’s telescopic sections is made significantly easier with the aid of the Kelly visualization system.
Thanks to the real-time display of the Kelly bar’s locking recesses on the cabin monitor, the operator is always informed about the actual distance to the next locking recess.
Colour indications inform the operator of when the bar can be locked.
Furthermore, the Kelly bar’s false positioning during the shake-off process is indicated through a warning signal.
Material handling
Liebherr is unveiling the newest generation of duty cycle crawler cranes with the brand new HS 8070.1.
The machine has a lifting capacity of 70 tons and is ideal for a wide range of uses, including material handling, deep base work or lifting work.
Using a modern self-loading system, the crawlers can be easily disassembled for transportation, reducing the transport weight to less than 35 tonnes.
Instead of just one counterweight, the machine now has a modular system.
Depending on the application, the duty cycle crawler crane can be individually equipped.
The boom of the HS 8070.1 is compatible with the HS 8100.1, allowing customers to use attachments on both machines.
The new floating A-frame system ensures higher performance in dynamic applications compared to the fixed system.
It also simplifies and speeds up the assembly and transport of the machine.
The user-friendly design extends to the tank’s neck, easily accessible via the upper carriage platform.
