RILLHOLT RH-UL-013 Underground LHD LoaderUnderground Loaders
Development headings and production stopes larger than 3.4 x 3.4 m in underground mines
Overview
The RILLHOLT RH-UL-013 is a 7 t diesel underground LHD for headings above 3.4 x 3.4 m, driven by a Cummins QSC8.3 engine rated 179 kW with 1,040 N.m maximum torque (Tier 3) through a DANA R32000 transmission and axles. Its 3.5 m³ standard bucket develops 117 kN shovel force and 180 kN tractive force against a 140 kN tipping load, and a 350 L fuel tank supports long shifts. Standard exhaust purification, Hardox 500 cutting edges, Eaton hoses, PVBR wiring, IP67 connectors and up to 80% floor-level routine maintenance suit sustained production loading.
