KH environmental protection type open-air crawler rig
KGH3 series low wind pressure environmental protection type open-air crawler drilling rig

Strong and reliable power

Use two-cylinder diesel engine as power, traction power is big, strong climbing ability; the whole machine vibration is small, work smoothly.

Using patent diesel engine intake adjusting device (patent no : 2008820087606.3) plus desert air filter and oil filter triple filter perfect combination, to enhance the boring rig to adaptability the bad environment, prolong the service life of diesel engine


Flexible drill arm

Using drill arm, by controlling the oil cylinder of the flexible can adjust drilling Angle and horizontal hole’ height, enlarged the scope of drilling, improve the product adaptability.


Reliable hydraulic pump group

Using two independent gear pump supply oil, reliable work, strong adaptability, easy maintenance

Adopt gear transmission and soft features connection, compact structure, smoothly operation


Reliable hydraulic system

Using special hydraulic components, improve the stability and reliability of the system.

Add the oil cooling equipment, eliminate the influence of hydraulic oil heating to the system
