1. It is equipped with 8×8 all-wheel-drive automotive chassis, meeting the national IV emission standards and equipped with off-road radial tire of transverse pattern with strong off-road performance.
2 .The full hydraulic top drive can achieve steeples speed variation, and the torque can adjust automatically to adapt the construction of different strata, energy conservation and high efficiency.
3.The Max. Stroke of the top head drive is 12000mm, which can meet the requirement of 9600mm drill pipe.
4.The equipment of the floating axis can protect the thread of the pipe effectively and solve the jet power of the drilling rig to the top drive when on DTH hammer drilling.
5. The hydraulic system adopts load sensitive control system, which can reduce the heating value and more energy-saving.
6.The automatic pipe loader mechanism can not only increase the construction efficiency but also reduce the labour intensity.
7.The Drilling rig is equipped with mud pump foam pump and two air interfaces, users can adopt mud drilling or compressed air and DTH hammer drilling directly.
8. The major parts imported from international famous brand products with stable function and long lifetime. Such as decelerator、 hydraulic motor and feeding & drawing ropes.
