Strong propulsion, slewing mechanism

Slewing mechanism of high power hydraulic motor drive, provide powerful torque reserve for boring rig, reduce pipe-sticking probability.

Propulsion mechanism of high power hydraulic motor drive, can generate 20 KN lifting force,  to adjust the propulsion control valve of regulating valve, The best propulsion can obtain  conditions required.

Flexible drill arm

Using drill arm, by controlling the oil cylinder of the flexible can adjust drilling Angle and horizontal hole height, enlarged the scope of drilling, improve the product adaptability.

Reliable hydraulic pump group

Using two independent gear pump supply oil, reliable work, strong adaptability, easy maintenance

Adopt gear transmission and soft features connection, compact structure, smoothly operation

Using special hydraulic components, improve the stability and reliability of the system.

Add the oil cooling equipment,eliminate the influence of hydraulic oil heating to the system

Centralized control of operating mechanism

Boring rig design with the advanced hydraulic system and fully functional gas path system, and all actions are centralized control,convenient operation.

Operating hydraulic control valve, which can realize thedrill arm lifting, swing and the drilling stand pitching, pivot angle, forward (backward), and other functions, ensure multiple drilling holes and the stability of the drill rig.

Operation the pneumatic control valve, which can realize the opening of the oil pump and boring rig advance (promote), rotary, impact and ensure the high efficiency of boring rig.
