For Gold Mine Use, Large Successful HFU-3A Underground Mining Products

I. CZPT Introduction
HFU-3A full hydraulic underground main drilling machine is mostly utilized in the fields of coal, geology, metallurgy and engineering. It is used for drilling huge diameter Gas suction gap in mines, gallery as nicely as coal mine, h2o injection hole, and large diameter Horizontal hole. It can meet up with the big diameter Roller drilling, tough tungsten-carbide drilling and percussive-rotary drilling.

II. Major Functions:
one. It is independent in framework, little in measurement, gentle in excess weight, versatile in motion and handy in operation.
two. The hydraulic pump is pushed by explosion-proof electrical motor by means of working technique, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the motion of drill head is recognized by oil cylinder & chain double speed mechanism.
three. CZPT chuck can fulfill the purpose of shackles and energy-off defense.
four. The sliding and extending & retracting function of the mast can make it handy for the bottom of mast to touches the floor or platform, therefore the drill rig will be much more stable.
5. The swinging arm and mast can do luffing motion, which fulfill the request of multi-angle drilling.
6. The selection of spindle rotating speed is broad and the torque is massive.
