The crane is remarkably compact for its performance and the 10 x 8 x 10 drive, combined with active rear axle steering, providing better manoeuvrability for job sites with constraints.
The carrier is powered by a 6-cylinder Liebherr turbo-diesel engine developing 370 kW and the ZF 12-speed gearbox feature the AS-Tronic automatic control system. The hydraulically operated four-point outriggers are self-levelling with an electronic indicator.
The superstructure itself is also powered by a 4-cylinder Liebherr turbo-diesel engine which has an output of 180 kW. Electronic control is provided by Liebherr’s own LICCON computer system via twin self-centring joysticks located in the operator’s seat armrests, with LICCON also incorporating safe load indication and a diagnostic and testing system.
The ergonomically designed, the state-of-the-art cab is comfortably appointed with full instrumentation and can be tilted backwards hydraulically for optimum visibility during lifting operations.
