KT11S Crawler Type Down the hole Rig China's first design !

No.1 factory in China developed this drill rig using just one engine powering compressor and drill, until now no other factory in China could matchs this(they use two engines which enery consumption....), also we achieve world class level performance in aggregate quarrying.

Advantages of New KT11S:

1. 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.

2.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.

3.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.

4.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.
