The full hydraulic underground drilling rig RCH-4A is applied to the following fields: coal, metallurgy, geology, and engineering, etc. It is used in the large-diameter gas drainage and the water injection hole of mine, tunnel, and coal mine. It is also used in large-diameter horizontal drilling surface engineering.
1. This drilling rig is separate in structure, small in size, light in weight, flexible in movement, and convenient in operation.
2. The hydraulic pump is driven by the explosion-proof electric motor through the operating system, then the hydraulic pump enforces the hydraulic motor to make the drill head rotate, and at the same time, the movement of the drill head is realized by the oil cylinder & chain double speed mechanism.
3. Hydraulic chuck can satisfy the function of shackles and power-off protection.
4. The sliding and extending & retracting function of the mast makes it convenient for the bottom of the mast to touches the ground or platform, thus this hydraulic drilling rig will be more stable.
5. The swinging arm and mast can do luffing movement, which satisfies the request of multi-angle drilling.
6. The range of spindle rotating speed is wide and the torque is large.
