The latest generation of duty-cycle crawler cranes from Liebherr, the HS 8070.1, was recently showcased at bauma 2022. The machine has a lifting capacity of 70 t and is ideal for various applications, including material handling, deep foundation and lifting operations.
Using a new jack-up system, the crawlers can be easily disassembled for transportation, so reducing the transport weight to less than 35 t. The platforms and railings must no longer be removed before transportation, said Liebherr.
Instead of a single counterweight, the HS 8070.1 now features a modular system. Thus, the user can mount the counterweights individually as required, depending on the application.
In addition, the boom of the HS 8070.1 is compatible with the HS 8100.1, so customers can use attachments such as the HSG 5-18 slurry wall grab 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, according to Liebherr. 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 uppercarriage.
