RILLHOLT RH-UD-004 Underground Hydraulic JumboUnderground Drilling Rigs
Development drifting and face drilling in headings up to 34 m² in underground metal and non-metal mines
Overview
The RILLHOLT RH-UD-004 is a single-boom hydraulic tunnelling jumbo covering headings up to 34 m². An LD50 rock drill (18 kW) runs on an LG-CF4300 feed with 4,305 mm rods and 4,050 mm hole depth, drilling 32-64 mm holes and 76-127 mm reaming holes, mounted on an LG-B26NV boom with automatic parallel holding, 1,200 mm boom extension and 1,600 mm feed extension. A 55 kW power pack, 380 V electric drive with 70 kW total input and LG-CBI drilling control support fast cycles, and the 11,200 x 1,660 x 2,400/2,890 mm carrier at 11,800 kg runs a YC4D90 66 kW China III engine with converter, gearbox and drive axles.
