Hydraulic Borehole Blasting Drilling Rig is a crawler type drilling rig, which is used in open pit mine factories. The screw air compressor works as a power source for the blasting borehole drilling rig. Mainly used for drilling boreholes on stones and then blasting the stone into pieces. The percussion device installed on the end of the drilling pipe will hammer the rock while drilling. The crawler blasting drilling rig adopts a hydraulic rotary motor, the rotation speed is high and the torque is big. Two steel tracks make it stronger in working in harsh conditions area, so you can also call it a track drilling rig. Hydraulic Crawler Blasting Drilling Rig is different from a water well drilling rig, it drills not that deep, usually, 30-40mm, and the diameter of the borehole is around 205mm.
Borehole diameter is 90-130mm
Borehole depth is 30m
Hydraulic Crawler Blasting Drilling Rig can drill 2m in depth one time.
The air pressure it requires is 0.7-1.4 Mpa, the air usage is 7-15m3/min. A mobile trailer diesel screw air compressor will meet the needs.
The skid beam of the Hydraulic Crawler Blasting Drilling Rig can move right and left, this function makes it the ideal blasting drilling rig for drilling boreholes in the stone.
The diesel engine can be yuchai or commins, if you have enough budgets, you can choose commins diesel engine. But yuchai is not that bad at all, it is widely used in china in farming machines.
The hydraulic system is very stable, it is specially designed for Hydraulic Crawler Blasting Drilling Rig.
