China top DF-Y-4 portable hydraulic rotry drilling rig for geological prospecting
DF-Y-4 hydraulic rotary drilling rig is a new type high speed diamond core drill rig, designed according to the development of geological work in China and developed to meet the requirements of clients. It has been identified in 1976, and rewarded with the Chinese National Silver Medal in 1988. The DF-Y-4 model has been sold all over the world.
DF-Y-4 Hydraulic 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.
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 dis assembly (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.

Working site:
Established in 1970s, Zhengzhou Defy has growned into one leading drilling rig manufacturer in China, specilizing in drilling rig technology R&D, manufacturing, etc. We spark on conventional rotary drilling rig, new pneumatic drilling rig and are inventing another drilling rig with performance same as pneumatic one, but with much less investment for users.
Our rotary drilling rigs are widely used for water well drilling, irrigation well drilling, geothermal hole drilling, mining blast hole drilling, construction pile work drilling, air-conditioner hole drilling, etc.
DEFY Brand drilling rigs have been widely exported to Chile, Russia, Australia, Malaysia, Kenya, Tansanzia, Zambia, South America, Peru, Zimbabwe, etc.
Every customer is very welcomed to our factory for visiting driling rig, talking onsite and details. ^_^
