Development drifting and face drilling in headings up to 24 m² in underground mines
Overview
The RILLHOLT RH-UD-003 is a single-boom hydraulic tunnelling jumbo for development headings up to 24 m². Its LD60 rock drill (20 kW) works on an LG-CF3700 feed with 3,700 mm rods and 3,440 mm hole depth, drilling 32-45 mm holes and 76-127 mm reaming holes, carried by an LG-B14F boom with automatic parallel holding, 2,000 mm feed extension and 360 degree rotation. A 55 kW hydraulic power pack, 380 V electric drive with 70 kW total input, LG-CBI drilling control, FOPS certified canopy, and a 9,850 x 1,400 x 1,860/2,750 mm carrier at 10,500 kg support face drilling in underground headings.
