Hfu-3A Underground Drilling Machine

Hfu-3A Underground Drilling Equipment

I. CZPT Introduction
HFU-3A complete hydraulic underground core drilling machine is mostly utilized in the fields of coal, geology, metallurgy and engineering. It is utilised for drilling massive diameter Gas suction gap in mines, gallery as effectively as coal mine, h2o injection hole, and big diameter Horizontal hole. It can satisfy the big diameter Roller drilling, tough tungsten-carbide drilling and percussive-rotary drilling.

II. Primary Attributes:
1. It is individual in structure, tiny in measurement, gentle in fat, versatile in motion and hassle-free in procedure.
2. The hydraulic pump is driven by explosion-evidence electrical motor by means of running 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 velocity system.
three. CZPT chuck can fulfill the operate of shackles and power-off defense.
four. The sliding and extending & retracting operate of the mast tends to make it handy for the base of mast to touches the floor or platform, hence the drill rig will be far more secure.
5. The swinging arm and mast can do luffing motion, which fulfill the request of multi-angle drilling.
six. The selection of spindle rotating speed is vast and the torque is big.
