The descriptions of the diesel engine DTH compressed air borehole drilling equipment.
The diesel engine DTH compressed air borehole drilling equipment is a type of DTH drilling rig, this DTH drilling rig is specially designed to drill through hard rocks. The drilling depth of this DTH borehole rig equipment is 280m and the drilling diameter is 140mm to 305mm. it is called DTH borehole drilling equipment, it is because the water well drilling rig is working with a screw air compressor to drill. The diesel engine DTH compressed air borehole drilling equipment is equipped with two steel tracks and it is very swift moving in the mountainous area.
