Safety and stability in travelling mechanism:

Due to low gravity and large ground clearance, it is easy to run across rugged roads.

With advanced automatic crawler leveling function, the drilling rig travels smoothly and steadily and it is subjected to significantly reduced impact from the ground to guarantee safe travelling.

Driven by high power pneumatic motor, the drilling rig has strong climb capacity and large traction.

The brake gear is linked to walking control mechanism, so that the brake will work when the rig stops to guarantee stability and safety of the drilling rig during drilling operation and traveling on a slope.

It is convenient and flexible that walking control valve is usually set to braking state and it controls the movement of left and right crawlers respectively to realize movement forward and backward and steering.

Strong and reliable power

Powered by double cylinder diesel engine, the drilling rig has large traction power and strong climb capacity; due to small body vibration, it operates smoothly.

The perfect combination of patent diesel engine intake adjusting device (patent No.: 2008820087606.3) plus desert air filter and tertiary oil filter enable the drilling rig to be more adaptive to severe environment and extends service life of the diesel engine.

Drill boom

It using the better trolley travelling mechanism and the circular boom, novel structure, convenient adjustment, expands the range of drilling,It can drill the hole low level.

Strong feed and rotation mechanisms

New slewing mechanism consists of a large torque hydraulic motor and planetary cycloid reducer, provide a powerful vehicle for the drilling torque reserve, reducing the chance of sticking. Hydraulic cylinders plus pulley combinations of propulsion mechanism, can produce lifting force 20KN, regulating the control valve on the regulator, can be obtained best propulsion of optimum conditions.
