Hfu-4A Hydraulic Underground Tunnel Core Drilling Rig

HFU-4A CZPT underground tunnel Main Drilling Rig

Merchandise Description                                                                                       
HFU-4A total hydraulic underground core drilling device is primarily used in the fields of coal, geology, metallurgy and engineering. It is utilized for drilling huge diameter Fuel suction gap in mines, gallery as effectively as coal mine, drinking water injection hole, and big diameter Horizontal hole. It can meet the huge diameter Roller drilling, difficult tungsten-carbide drilling and percussive-rotary drilling.

Primary Characteristics
1. It is separate in structure, modest in dimension, light-weight in excess weight, flexible in motion and practical in operation.
2. The hydraulic pump is pushed by explosion-evidence electrical motor by way of running system, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the identical time, the movement of drill head is recognized by oil cylinder & chain double speed mechanism.
three. CZPT chuck can satisfy the function of shackles and energy-off safety.
four. The sliding and extending & retracting purpose of the mast tends to make it hassle-free for the base of mast to touches the ground or platform, therefore the drill rig will be a lot more stable.
five. The swinging arm and mast can do luffing motion, which fulfill the ask for of multi-angle drilling.
6. The range of spindle rotating speed is broad and the torque is big.
