Characteristics 1. DF-H-4 granite drilling machine of full hydraulic and rotator adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties in the world. 2. It is also the developing direction of drilling technique and drilling equipment in China.This type of drill rig could substitute imported products. 3. It could be applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries. 4. The drill rig is equipped with a series motor driving pump. The feeding and lifting of rotator are driven in the structure of cylinder directly pushing, with a 3.5m(11.5 feet) stroke. The rotation of spindle is driven by a single engine. It has four mechanical shifts of range of speeds, and the speed could be adjusted hydraulically with stepless change. 5. The rig is simple in structure. It is light and easy for transference; the mast has the functions of sliding and touching ground; the spindle lifted and lowered with hydraulic cylinder; it could be folded for transport and relocation.

Company Information 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 drilling rigs are widely used for geological investigation, water well drilling, irrigation well drilling, geothermal hole drilling, mining blast hole drilling, construction pile work drilling, air-conditioner hole drilling, etc. DEFY Brand portable core 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. ^_^
