Reliable hydraulic pump aggregate

Low gravity center,high ground clearance, It can travel on the rough terrains. Special wheel motor drive, strong climbing ability, low failure rate.

Advanced automatic balancing and braking system make the dill can travel stability,driving safety.

Prevent to take off the chain set is improve the properties of dirll.

It can travel without compessor.

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.

New 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.
