DF-Y-4 Rock Core Drilling Rig can be driven by Deutz F4L 912 diesel
engine or Weichai diesel engine
or 30KW electric motor. The drill has 8 rotary speed stage, the
Max. speed 1588 rpm, the min. speed 101 rpm, so it is suitable for various drilling for solid mineral deposits with diamond or tungsten-carbide
It is also suitable for engineering geological subterranean water
explorations as well as explorations of
shallow layer oil and natural gas, and can be used to drill holes
for ventilation and drainage of main Gallery.
II. Main Features
1. The rig is in higher rotational speed and rational range of
rotational speed; large torque in low speed
2. The drill is suitable in the mountain area because of light weight
for easy transport and convenient
disassembly (to be disassembled into nine parts).
3. With compact structure and reasonable layout, and all exposed,non
overlapped components, it is
easier for maintenance and repair.
4. It is convenient for you to treat trouble with two reverse speeds.
With low center of gravity, the rig is
reliable and stable in high speed drilling.
5. The operation levers are concentrated, so the operations are
reliable and convenient.
6. Fitted with meters, the circumstances can be controlled easily in
7. The transmission is separately driven for drill rig and mud pump;
it is easier for the location arrangement
with less space occupying.
