RILLHOLT RH-UL-010 Underground Electric LHD LoaderUnderground Loaders
Development headings, production stopes and confined workings larger than 3.4 x 3.4 m
Overview
The RILLHOLT RH-UL-010 is a 7 t electric underground LHD for headings above 3.4 x 3.4 m, driven by a 90 kW 1,000 V HM2-280M squirrel-cage motor with 1,568 N.m maximum torque through a DANA C273 torque converter, DANA R32000 transmission and DANA 16D axles. Its 3.5 m³ standard bucket delivers 117 kN shovel force and 126 kN tractive force, and a 150 m 3 x 35 + 3 x 6 + 2 x 2.5 trailing cable powers the loader. Electric drive keeps diesel exhaust out of the heading, with 380/660 V systems available as options.
