Liebherr exhibits new R 954 C SHD crawler excavator with shovel at the 2010 ‘Bauma’

At the 2010 ‘Bauma', Liebherr is exhibiting its new R 954 C SHD crawler excavator with shovel. Conceived for mining work, this excavator has a service weight of approximately 62 metric tons. The machine's specific configuration includes the basic unit with 9.0 t of ballast, an operator's cab raised by 800 mm and 500 mm wide double-plate track pads.

The R 954 C SHD develops a crowding force of 435 kN (44.3 t) and a breakaway force of up to 355 kN (36.2 t). The excavator's maximum crowding length is 3.38 m, and with its discharge height of up to 6.30 m it can load all normally used dumper trucks in the relevant size categories.

The R 954 C SHD's wear-protected shovel has a capacity of 3.5 c. m. when working with material with a specific weight of 1.8 t / cu. m. The shape of the shovel has been chosen for effective penetration of the material and a high filling level. The well-proven parallel kinematics developed by Liebherr ensure efficiency and ample strength. Crowding force is increased continuously to a maximum over the last third of the crowding distance, and the shovel moves in parallel without subsequent adjustment. This ideal equipment concept needs no additional components and therefore avoids imposing extra weight on the working equipment.

The robust SHD undercarriage uses the longitudinal members from the next-larger crawler excavator model, the R 964 C. Together with the specially modified X-pattern centre section, these ensure exceptionally high stability and optimal force flow patterns. The new undercarriage design and the use of double support-roller bearings contribute to the undercarriage's unusually long trouble-free operating life.

The R 954 C SHD is driven by a Liebherr inline six-cylinder engine with a pump-pipe-nozzle fuel injection system. This engine, which is turbocharged and equipped with a charge-air intercooler, develops 240 kW (326 hp) at 1,800 rpm, and is one of the latest generation of Liebherr emission-optimised diesels. A semi-automatic central lubricating system is standard equipment on the R 954 C SHD.

Special protective equipment for use with a demolition ball, for instance piston rod, lubricating line and slewing gear protection, is available from the manufacturer as an optional extra.
