1. National V chassis is adopted as the transportation tool which has a strong cross-country performance. The system of lifting, rotation and circulation are mounted on the truck. The good travelling performance can be suit to the drilling operation of the flatland, desert, marsh and gobi area. The truck can drive on the road with the license plate conformed to the national law, moreover, the vehicle purchase tax is remitted.

2. The power unit with large torque is matched to accomplish the stepless speed-adjustment. The torque is adjusted automatically to be suitable for the different layer operation with a high efficiency and energy-saving.

3. The structure is that the top drive can be lifted and lowered through the wire rope driven by the oil cylinder. The slow drilling is accomplished by the variable displacement pump to increase the working efficiency. During the drilling process, the hydraulic system can be set through the drilling mode according to the drilling speed of the DP and the needed pressure of the downhole. The pump flow and pressure is controlled to carry out a stepless speed adjustment on the drilling parameter, which is convenient to the user operation.

4. Max. stroke of the full hydraulic top drive power unit is 13400mm, meeting the needs of 9500mmDP and API II series casing pipe with a high operation efficiency.

5. Adapting to the variable technology drilling, the drilling rig is matched with air compressor, mud pump, foam pump and lubricator according to the needs. The users can accomplish the mud drilling and air drilling operation.

6.The drilling rig is operated in the condition of -35°～+50° environment.

7. The drilling rig is designed according to API specification, and then the key parts of the hydraulic system adopt the international top band.
