HYDX-4

I

．Brief Introduction

The HYDX-4 hydraulic core drilling rig 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. It is also the developing direction of drilling technique and drilling equipment in China. Under these circumstances, Lianyungang Huanghai Machinery Co., Ltd. has developed the HYDX-4 hydraulic core drilling rig successfully according to the situation of China. This type of hydraulic geological drill rig could substitute imported products. It could be applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater and other industries. The HYDX-4 hydraulic core drilling 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 steeples change. The hydraulic geological drill 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. The spindle hole is in large diameter.
