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.

Flexible drill boom

With flexible drill boom, it can adjust drilling angle and horizontal hole height by controlling expansion of the oil cylinder, thus extending the drilling range and improving product adaptability.

Reliable hydraulic pump aggregate

It uses two independent gear pump to supply oil, reliable, adaptable, easy to maintain.

It adopts gear drive and flexible connection and runs smoothly and steadily with compact structure.

Reliable hydraulic system

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

Additional oil cooling device, eliminating the influence of the hydraulic oil heat system.
