Product Description

Product Specifications of DFU-300 Water Well Drilling Rig:

DFU-300 hydraulic underground drill rig is mainly applied in the fields of coal, geology, metallurgy and engineering. It is used for drilling large dia. gas suction hole in mines, gallery as well as coal mine, water injection hole, and big dia. horizontal hole. It can meet the big dia. roller drilling, hard

tungsten-carbide drilling and percussive-rotary drilling.

Features

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 touch 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.
