Liebherr says its new R 9100 mining excavator sets standards in the 100-ton class for productivity, reliability, and cost efficiency. The excavator’s V12 engine has an output of 565 kW (757 horsepower) and, combined with the efficient hydraulic system, provides high digging and breakout forces. The specially shaped 6.8-cubic meter bucket increases penetrating power and fill factor. A wide catwalk makes access to the various mechanical assemblies easy. Other features include an operating weight of 110,100 to 114,000 kilograms; a machine monitoring and control system; and a new cab design.
