1.Safe and stable traveling system
Low gravity, great ground clearance, make cars easily make drill through rugged road.The advanced automatic balance system, not only makes drilling stable, also greatly reduced the impact of the car, and ensure the safe driving.
High-power motor drive and strong climbing ability, with great traction.
Brakes and walking operation method adopt linkage way, make parking to brakes, thus safeguarded car in slope rock drill and driving on stability and security.
Often set the state of the brake control valve to walk around the track, control crawler action, respectively about realize forward, backward, and steering, convenient and flexible.
Unique anti-off chain device greatly improved the reliability of Drill.

2.Centralized operating system
Drill carriage designed with advanced hydraulic system and completely functional gas circuit system. Centralized control ,operate easily.Hydraulic maneuvering valve can be achieved lift ,swing and drilling rig's pitching, swing, forward and back, also can make track equal. Ensure the stability of drilling rock hole in full dimension .Operating pneumatic manoeuvring valve can realize the pump opening and drill the advancement of car (ascension), and turn to dust collector, impact and set the dust collection, the blow function, ensure efficient car rock drill.

3.Powerful feeding and rotating system
Promote reducer drives adopt turbine and worm, which have a big push-pull effort and can reliaze self-locking. By adjust the press of the reducing valve, the push-pull effort and lifting speed can adjust at will according to needs
Slewing reducer drives adopt planet wheel, rotate speed is slow and torque is large. By adjust the press of the slewing reducer, the rotate speed and torque can adjust at will according to needs, to guarantee the best efficiency of down-hole and hammer drilling.
