KT series integral type high wind pressure open-air crawler rig
KT20 integral type high wind pressure open-air crawler drilling rig

introduction and Parameter:

1. Disc type automatic unloading rod system, automatic unloading rod drilling is 36 meters deep.

2. Carriage pendulum angle use the luffing mechanism, always swinging Angle 130 °(left 33 ° right 97 ° ), without  being in fulcrum free horizontal hole and vertical hole. The lowest level hole height 550 mm, the highest 550 mm.

3. Adopt the caterpillar electronic  engine, powerful, reliable in performance.

4. Adopt a single engine at both ends of the output of decorate, compact structure, easy maintenance.

5. High wind pressure large displacement air compression system (22 m3 / min, 25 bar) to ensure the percussive drilling rapidly.

6. Walking mechanism of automatic leveling function let jumbo more adapt to mine rugged mountain path.

7. Double hand soldering the entire guide drilling tools, to prevent the occurrence of deviation when drilling (Guide the impactor when opening, guide the drill pipe when drilling).

8. Adopt imported hydraulic parts and electrical appliances
