Hcr-8 full hydraulic core drilling rig is a kind of high efficiency and multi-function full hydraulic core drilling rig developed on the basis of R & D, production and user feedback of hydx series full hydraulic core drilling rig. The machine is suitable for plain, hilly area, high temperature, severe cold and other harsh environment. It is mainly suitable for metal and nonmetal solid deposit exploration, coalbed methane, natural gas, hydrological wells, geothermal wells, mine tunnels, ventilation and drainage holes and engineering rescue construction. It is widely used in geology, coal, metallurgy, nonferrous metals, petroleum, hydrology, engineering and other industries Gold drilling is one of the most excellent drilling equipment, which can meet the requirements of wire line coring, top drive drilling and other multi-functional drilling.

Full hydraulic drive, steel crawler walking, combined mast, power machine, main and auxiliary hoists, mud pump and other integrated layout, compact structure, centralized control, flexible and convenient.

The hydraulic system adopts pilot control, load sensing, electric and hydraulic proportional joint centralized operation control, and can be equipped with support device.

3. The feeding and lifting of the power head adopts the double speed structure of oil cylinder chain, the lifting force reaches 295kn, and the feeding force reaches 152kn

The main shaft of the power head is driven by double motors, supplemented by a three speed mechanical gearbox. The maximum output torque of the main shaft reaches 7200 N.m (170 RPM), which effectively meets the requirements of high-speed and high torque construction.

The power head adopts the hydraulic motor rack translation device to make the main shaft deviate from the drilling hole, which is convenient for the construction of wire line coring and other machines and tools.

The front end of the mast is equipped with a clamping shackle, which is convenient for the operation of the drill pipe, reducing the labor intensity of the operator and improving the work efficiency.

7. The upper and lower worktables are convenient for operators to operate.

The orifice is equipped with hydraulic gripper and guide.
