The JK830 is a crawler mounted DTH drilling rig made for quarry and mine blast hole work. It drills 105-165mm holes with a 125HP diesel engine driving the hydraulic system, and it moves itself around the bench on steel tracks, so one operator can handle positioning, drilling and rod handling without a support vehicle.
Hole diameter: 105-165mm. Drilling method: DTH hammer. Engine: 125HP diesel. Air requirement: 12-21 m3/min at 17-21 bar (external compressor). Mast stroke: 4m. Track width: 300mm. Weight: about 13 tons. Transport: single lowbed trailer.
Note: the rig works with a separate air compressor - if you need one, we can supply a matched screw compressor in the same order. Spare hammers, bits and drill pipes are kept in stock for export.
