ZJ40T trailer-mounted Drilling Rig

Technical characteristics

1. The whole unit utilizes hydraulic + mechanical transmission which realizes the flexible stepless adjustment of speed of the drilling device and the trailer. The Caterpillar engine and Allision hydraulic transmission mate reasonably with high transmission efficiency and excellent safety. Utilization effectiveness of the engine is increased greatly.

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

3. The rig is equipped with complete hydraulic and pneumatic operating control system and double crown saver, which decrease the workers intensity of work and enhance the safety of operation.

4. The entirely forging brake rim and water circulating cooling system are used to increase the safety of braking and service life of the brake rim. They are also beneficial to environment.

5. Engine killing and overspeed device are equipped to meet the requirement of wellsite of oil and gas.

6. The chassis is heavy-load trailer which has good cross-country capability.

7.  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.

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