I. General
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
tipped bit.
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 hole.
7. The transmission is separately driven for drill rig and mud pump; it is easier for the location arrangement
with less space occupying.
1. Provide factory cost accessories all year
2. Engineers are available to service machine overseas or free training in factory
3. Online service 24hours*7 days
4. 12 months quality warranty for main body.
How to choose a suitable machine?
1. What will you do using drilling rig?
---For water project, core sample, soil test, mineral prospect or others?
2. The depth you need?
---For water well, generally, 30-200m. For core sample, 30-600m, even more.
3. Any requirements to hole diameter?
---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.
4. Working land condition?
A. soil, sand, weathered land, etc. soft stratum.
B. soil, sand, soft and hard rock stratum, mixed one.
C. Mainly hard rock, like granite.
