RILLHOLT RH-UL-007 Underground Electric LHD LoaderUnderground Loaders
Development headings, production stopes and ventilation-limited workings larger than 3.1 x 3.1 m
Overview
The RILLHOLT RH-UL-007 is a 4.5 t electric underground LHD for headings above 3.1 x 3.1 m, using a 75 kW 380 V motor (HM2-280S-4-75) through a DANA C273 torque converter and DANA R32360 transmission. Its 2.5 m³ standard bucket develops 98 kN shovel force with a 9,000 kg tipping load, and a 120 m 3 x 50 trailing cable feeds the machine. Electric drive removes engine exhaust from the working face, and the manual centralized lubrication, ROPS/FOPS canopy and 7,596 x 1,770 x 2,050 mm envelope suit confined headings.
