SCU-4A Full Hydraulic Underground Core Drilling Rig For Mineral Exploration
The full hydraulic underground drilling rig SCU-4A is applied to the following fields: уголь, металлургия, geology and engineering, и так далее. 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 the large-diameter horizontal drilling surface engineering.
Main Feature：
1. It is separate in structure, small in size, light in weight, flexible in movement and convenient in operation.
2. 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.
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 mast to touches the ground or platform, thus the drill rig will be more stable.
5. The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling.
6. The range of spindle rotating speed is wide and the torque is large.
Full Hydraulic Underground Core Drilling Rigs Application:
Underground core drilling rigs are used in mining for mineral exploration and extraction, geotechnical engineering and civil construction projects to determine soil properties, and in the oil and gas industry to optimize the production of wells and explore new reserves, и так далее.
