Liebherr-Wek Nenzing GmbH Debuts New Equipment

Liebherr-Wek Nenzing GmbH debuted three new machines and one new design recently for the deep foundation, material handling and lifting fields.

All the models include a brand-new design combining the classic Liebherr yellow with new black, gray and white accents. The company said the design reflects how longstanding tradition and company values unite with advanced technologies.

The design also places a higher level of safety emphasized, above all, by improved platforms and railings on the upper carriage. The design is more flexible, with an add-on wing for mounting lights or cameras. Inside the new cabin, operators will enjoy reduced noise, panoramic view and comfort 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 inclusion of stone protection.

For material handling, Liebherr unveiled the HS 8070.1, the newest generation of duty cycle crawler cranes, designed to be versatile and flexible.

The machine has a lifting capacity of 70 tons and is suitable for a multitude of applications, including material handling, deep foundation work or lifting work.

Using the new self-loading system (Jack-Up System) the crawlers can be easily disassembled for transportation, reducing the transport weight to less than 35 tons. The platforms and railings no longer must be removed before transporting.

Instead of a single counterweight, the equipment now has a modular system. The duty cycle crawler crane can be individually equipped, depending on the application. Additionally, the boom of the HS 8070.1 is compatible with the HS 8100.1. Therefore, customers can use attachments such as the slurry wall grab HSG 5-18 on both machines and install thicker slurry walls with a more compact machine.

As opposed to the fixed system, the new floating A-frame system ensures higher performance in dynamic applications, Liebherr said. It also simplifies and speeds up the assembly and transportation of the machine. The user-friendly design extends to the tank neck, which is easily accessible via a platform on the upper carriage.

For lifting, Liebherr debuted the LR 1200.1 unplugged and LR 1250.1 unplugged, the world’s first battery-powered crawler cranes. Both are driven by electric engines with a system performance of 255 kW.

Liebherr said there are no compromises regarding performance or availability when compared with the conventional versions. The LR 1200.1 unplugged has a maximum lifting capacity of 200 tons, and the LR 1250.1 lifts 250 tons. The new machines are emission free and have a very low noise level, an advantage in areas sensitive to noise, and also for the people working on the jobsite.

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 four 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.
