At Conexpo for the first time: Liebherr’s duty cycle crawler crane HS 8100.2

Liebherr has equipped the HS 8100.2 with 15 percent more engine power than its predecessor. The maximum winch line pull of 2 x 66,319 lbf (2x295 kN) has been increased by 9 percent. This increase in power is reflected in the strong performance. The duty cycle crawler crane can now be used with heavier slurry wall grabs – both mechanical and hydraulic. In dragline operation, the increased engine power results in better digging force and, in dynamic soil compaction, the drop weight can be raised again more quickly meaning higher productivity. Thanks to the newly designed rope lock on the winches, the rope can be changed more easily and more quickly. The booms of the HS 8070.1, HS 8100.1 and HS 8100.2 dual power are compatible with the new model and are flexibly interchangeable for Liebherr customers.

Focus on the user

The designers of the HS 8100.2 attached great importance to making the model particularly user- and service-friendly, and to offering the best possible safety. The walkway concept was adopted from the latest models in the HS series and applied to the Conexpo exhibit. Railings and platforms now remain on the uppercarriage during transport – just like the access ladder for service work on the roof, which has been elegantly integrated into the uppercarriage. Thanks to the compact width of 11.48 ft (3,5 m) and a weight of only 132,277 lb (60 t), the uppercarriage and the undercarriage can be transported in one piece, which ensures fast set-up and availability on the jobsite. As an option, the crawler side frames can be easily removed using a self-loading system.

The repositioned tank neck is easily accessible via the platforms on the uppercarriage. It is no longer necessary to climb onto the roof of the duty cycle crawler crane to carry out this work. For all main drives of the HS 8100.2, the operator has fill level indicators on the operator’s monitor, which reduces and simplifies servicing of the machine. If work should begin when it is dark, the operator can light up the access to the cab of the HS 8100.2 using a remote control and so get in safely.
