Radiant Hydraulic Roof Bolter is a rotary roof bolting machine with dust suppression system suitable for drilling vertical holes of 27mm to 43mm diameter & anchoring of roof bolts in underground mines in strata hardness upto 750 kg/cm2. It is a totally indegenous equipment with modular construction consisting of 3 main assemblies- drive unit, telescopic leg & control arm. It can run with tapping from any underground hydraulic machinery like SDL, LHD, Road Headers or preferably by an independent powerpack. The machine has all operational controls on the handle of the pivoting arm itself which can be pushed down near the leg where it is automatically locked facilitating easy transportation. During operation it allows total control as well as safety to the driller.
