KC series all pneumatic open-air crawler rig
KC120 all pneumatic open-air crawler drilling rig

Convenient maintenance of the hydraulic pump group

Gas motor drive hydraulic pump group and placed outside the hydraulic fluid chamber, oil pump and motor using the characteristics of soft connection and are free to dismount, make the pump running stable and reliable, and easy maintenance.

Strong propulsion, slewing mechanism

Promote the reducer adopts turbine. Worm drive, push-pull big, can realize self-locking

Rotary gear reducer adopts gear drive, low speed, torque big, easy maintenance

Centralized control of operating mechanism

Drilling rig design has the advanced hydraulic system and gas circuit system, all actions are centralized control, convenient operation.

Operating hydraulic control valve, which can realize the drill 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.

Working mechanism of safety and stability

Low gravity center, large ground clearance, can be easily through the rough road.

Advanced crawler automatic leveling function, not only make drill rig walk stability, and greatly reduced to the ground impact force of to the drill rig, ensure the driving safety.

High power pneumatic motor drive, strong climbing ability, has great traction.

Brake equipment and working operating mechanism adopts the linkage method, make the parking is the brake, so as to ensure the jumbo drilling operations and drive on the slope stability and security.

Normal brake condition Walking control valve separate control left and right  crawler move、realize forward、recede and turn to.
