Large Drilling Dia! Multi-Functional Underground Drilling Rig

Huge Drilling Dia! Multi-Purposeful Underground Drilling Rig (HFU-3A)

I. CZPT Introduction
HFU-3A complete hydraulic underground core drilling machine is mainly used in the fields of coal, geology, metallurgy and engineering. It is used for drilling massive diameter Gas suction hole in mines, gallery as effectively as coal mine, drinking water injection hole, and large diameter Horizontal hole. It can satisfy the large diameter Roller drilling, hard tungsten-carbide drilling and percussive-rotary drilling.

II. Primary Characteristics:
one. It is separate in structure, small in size, gentle in excess weight, adaptable in motion and convenient in procedure.
two. The hydraulic pump is pushed by explosion-evidence electric motor by means of running technique, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the very same time, the movement of drill head is recognized by oil cylinder & chain double velocity system.
three. CZPT chuck can satisfy the purpose of shackles and energy-off security.
4. The sliding and extending & retracting function of the mast makes it handy for the base of mast to touches the ground or system, thus the drill rig will be a lot more stable.
five. The swinging arm and mast can do luffing motion, which satisfy the request of multi-angle drilling.
6. The variety of spindle rotating velocity is broad and the torque is big.
