1 With a very high rate of speed and a reasonable range of steps. 2 Low speed high torque

Detailed Product Description   GENERALIn order to meet applications of hydrographic well drilling and engineering geological exploration or construction, fit for technology of wire line core drilling and reverse circulation drilling, we have designed XY-4-3 spindle type core drilling rig. It is developed on XY-4 drill. The central opening dia of drill head is increased, and we add a derrick, a self-traction device, as well as a auxiliary transmission gear box.

The drilling rig can be used not only in core drilling, but also in engineering geological. If the drill is equipped with a 22 kW of 30 kW, 6 poles electric motor, the lowest speed of the spindle is 24r/min
