SCU-3A Portable Hydraulic Underground Core Drilling Rig 350m
Underground Core Drilling Rig General Introduction:
SCU-3A hydraulic underground drill rig is mainly applied in the fields of coal, geology, metallurgy and engineering. It is used for drilling large-diameter gas suction hole in mines, gallery as well as coal mine, water injection hole, and large-diameter horizontal hole. It can meet the large-diameter roller drilling, hard tungsten-carbide drilling and percussive-rotary drilling.
Portable Underground Core Drilling Machine Main Features:
- It is separate in structure, small in size, light in weight, flexible in movement and convenient in operation.
- The hydraulic pump is driven by explosion-proof electric motor through operating system, then the hydraulic pump enforces hydraulic motor to make drill head rotate, and at the same time, the movement of drill head is realized by oil cylinder & chain double speed mechanism.
- Hydraulic chuck can satisfy the function of shackles and power-off protection.
- The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable.
- The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling.
- The range of spindle rotating speed is wide and the torque is large.
