Product Description
DF-H-8 Deep Hole Core Drilling Machine
Production Description
DF-H-8  has been  the  dominant type rig  for  solid  mineral deposits prospecting in developed counties in the world. It is also the developing direction of drilling technique and drilling equipment in China.This type of drill rig could substitute imported products.  It could be applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries.The drill rig is equipped with a series motor driving pump. The feeding and lifting of rotator are driven in the structure of cylinder directly pushing, with a 3.5m(11.5 feet) stroke. The rotation of spindle is driven by a single engine. It has four mechanical shifts of range of speeds, and the speed could be adjusted hydraulically with stepless change.The rig is simple in structure. It is light and easy for transference; the mast has the  functions of sliding and touching ground; the spindle lifted and lowered with hydraulic cylinder; it could be folded for transport and relocation.

The lifting and propulsion of rotating head is driven by hydraulic cylinders.
The rotation of rotating head is driven by hydraulic motor.
The mast lifts up and lows down by hydraulic cylinders,more efficiency.
The mast can be folded for transportation and storing.
Mounted on crawler,easy to move.
