Light weight underground core drilling rig JKD1900S for coal mining drilling with 250m drilling capacity
Characteristics
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.
Application
The small, compact design of the JKD series underground core drilling rig for narrow spaces makes it ideal for use in narrow tunnels or in galleries. Quick and easy to set up, the JKD series core drilling rig’s mechanized rod handling, hinge-mounted rod holder, and rotation unit mean flexible, efficient drilling.
