Mining Hydraulic Underground Borehole Rotary Drilling Rig /Rock Drilling Rig/Pneumatic Rock Drill Rig Manufacturer

ZQLC-1200/11.9S crawler drill truck for coal mine is an upgrade product of our company"s drill truck series. It is powered by compressed air and equipped with crawler type walking mechanism. It can be widely used in coal mines at different angles in mines. Drilling holes for gas holes and discharge pressure holes and geological exploration.

The advantages of the rig are as follows:

1, high security, compressed air as the power source, no wires to access, safer and more convenient to use.

2, high power and high efficiency - the performance of this rig is reliable, the motor uses a unique gas path layout.

3, the machine is powerful, small in size, can walk freely in narrow lanes, easy to move, workers are more labor-saving.

4, in any hard and soft medium drilling construction can maintain more than 11KW power output. This machine has a lateral long distance across the obstacle hole punching.

5. The base of the rig is equipped with a rotating compass, which can be rotated at any angle by 360 degrees horizontally and the lifting device with locking positioning can greatly save the stability of the drilling time and improve the stability of the drilling rig.

6 large propulsion - the rig propulsion mechanism uses independent high-efficiency motor drive, and with multi-head worm turbine drive, achieves high thrust and high efficiency.

7, stepless speed regulation - valve body structure, realizes the slewing mechanism of the rig slewing mechanism, the feed speed and the feed force are infinitely adjustable, and cooperate with the independent propulsion mechanism to ensure that the swing power and the feed power are always proportionally distributed. The drilling efficiency is significantly improved.
