Drilling devices are mounted on the carrier, thus, the removability of the rig is increased. The assembling and preparatory time is shortened and the effectiveness of the rig is increased.

The heavy duty carrier is 14*8constant drive, self-propelled, equipped with power steering system and having a good cross-country capability.

The rotary table can realize forward /reverse shift, suitable for all kinds of drilling pipe rotary operation. It is equipped with anti- torque release device to ensure that the drilling pipe deformation energy can safely release.

Designed according to API International specifications, meeting the HSE requirement and the requirement of international bidding.
