General Introduction
The leading core drill rigs in the developed countries are full hydraulic operated type, which adopt the technology of wire-drawing core with diamond tip. This type of drill rig is also the main development trend in the field of drill rig technology and related equipment. Under the international and domestic trend, our factory has developed the YDX-4 Full Hydraulic Operated Core Drill Rig. This type of drill rig can take the place of imported products and be applied in the fields of geology, metallurgy, core mines, petroleum, natural gas and underground water exploration.
The drill rig is equipped with a series motor driving pump. The equipment and the pump are in two separated units. The feeding and lifting of rotator are driven by a series motor with gear and chain with a long stroke. The rotation of spindle is driven by a single engine. It has four mechanical shifts, and it speed could be adjusted by hydraulic pressure with stepless speed change.
It is a light, full hydraulic core drill rig. The core could be obtained at the earth's surface by using the drill rig. The rig has a simple structure. It is light and easy for transference; The mast has the functions of sliding and touching ground; The spindle lifted and lowered with oil cylinder; It could be folded for transport and locating. The spindle has a big diameter hole.
