KG940A Pneumatic And Hydraulic crawler drill rig

contact supplier for KG940A Pneumatic And Hydraulic crawler drill rig

A.Powerful feeding mechanism and rotating system1. Rotating system driven by high power hydraulic motor provides strong torque reserve and reduces the sticking drilling probability.2. Feeding mechanism driven by high power hydraulic motor can generate 20KN lifting power. Adjusting the pressure regulating valve on the control valve can get favorable driving power required by the working condition.

B.Adjustable boomBoom is adjustable. The angle of drilling hole and height of horizontal hole can be adjusted by controlling the stretch-out and draw-back of the hydro-cylinder.

C.Reliable Hydraulic Pump System

1.Oil supplied by two independent gear pumps, reliable operation, strong adaptability, easy maintenance. 2. Adopt gear transmission and soft connection, possessing compact structure and stable operation.3. Adopt special hydraulic components. That improves the system’s stability and reliability.4. Install oil liquid cooling device, to eliminate the exothermic hydraulic oil’s influence to the system.

D.Centralized Operating System

1.Designed with advanced hydraulic system and functional gas supply system, all actions can be centralized controlled, easy to operate.

2. Running the hydraulic operating valve can lift or swing the boom, and adjust the pitching, swing angle and forward or backward moving of drilling rig, and also level the crawler.

3. Running the pneumatic operating valve can open the oil pump, and realize the crawler drilling rig’s function of lifting, rotating and impacting, to ensure the high efficiency rock drilling.

Safety and stability of the mobile mechanism

·Low gravity, ground clearance achieved great, make drill car can easily go through bumpy road.

· Advanced automatic balance system, make not only drill garage walk stable, and greatly reduced drill car wallop, guarantee the safe driving.

· High-power motor drive, and their climbing ability, with large traction.

· Brakes and walk manipulated mechanism choi linkage mode, use parking brake, thus safeguarding namely for drilling in slope rock and car driving with stability and security.

· Often buy braking street maneuvering valve respectively controlled movement, realized the caterpillar around move forward, backward, and steering, convenient and flexible.

· Unique resistance from chain device, which greatly improves the reliability of the drill car.

Centralized control operation

· Drill car design has the advanced hydraulic system and a complete function pneumatic system, all movements are centralized control, convenient operated.

· Operating hydraulic maneuvering valve, which can realize the lift, swinging arm drill and drill frame of pitch, angular, translation (back) and crawler adjustment function, guarantee the equality of intersectorial drill hole drilling and drill car stability.

· Operating pneumatic maneuverings valve, which can realize oil pump is open and drill car propulsion (increased), slewing, impact and dust collector of dust collection, counter blowing function to guarantee a efficient rock drill car

Strong propulsion, rotary organization

· Propulsion reducer worm-gear, worm transmission, big push pull, and can realize the lock, By adjusting the advanced of the pressure reducing valve pressure, making push pull and push (increased) speed can be arbitrarily regulate according to need.

Rotary gear reducer, using the planet round transmission, speed, low torque force. By adjusting the rotary valve pressure makes speed and torque according to need to arbitrarily regulate, and to ensure the best DTH drilling efficiency.

Flexible drill arm

· Use mobile drilling of arm, by controlling the oil cylinder telescopic can dip and level of drilling hole high-speed height, expanded the scope of drilling, improve the product adaptability.
