I&period CZPT Introduction

HFU-3A entire hydraulic underground main drilling machine is mostly used in the fields of coal&comma geology&comma metallurgy and engineering&time period It is utilized for drilling massive diameter Fuel suction gap in mines&comma gallery as properly as coal mine&comma water injection gap&comma and large diameter Horizontal gap&period It can meet the large diameter Roller drilling&comma hard tungsten-carbide drilling and percussive-rotary drilling&time period

II&time period Principal Features&colon

1&time period It is different in composition&comma modest in dimension&comma mild in bodyweight&comma flexible in movement and handy in procedure&period
two&period The hydraulic pump is driven by explosion-proof electric motor via functioning method&comma then the hydraulic pump enforces hydraulic motor to make drill head rotate&comma and at the identical time&comma the movement of drill head is recognized by oil cylinder & chain double velocity mechanism&interval
three&period CZPT chuck can satisfy the operate of shackles and power-off protection&period of time
four&interval The sliding and extending & retracting function of the mast tends to make it handy for the bottom of mast to touches the floor or system&comma therefore the drill rig will be far more secure&period
5&time period The swinging arm and mast can do luffing movement&comma which satisfy the request of multi-angle drilling&interval
6&period The range of spindle rotating pace is vast and the torque is big&period of time
