The core drill rig of full hydraulic and rotor adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties of the world. The rig is light, simple in structure, and easy for transportation. The mast has the functions of sliding and touching the ground, the spindle lifted and lowered with a hydraulic cylinder. It could be folded for transport and relocation. The spindle hole is in large diameter.
HFDX-4+ full hydraulic core drilling rig is applied to exploration and prospecting of geology, metallurgy, coal, petroleum, natural gas, groundwater, and other industries.
