API & ISO Certified Oilfield Handling Tools, CDQ Sucker Rod Elevator
1. Description
CDQ(S) Sucker Rod Elevators series are important apparatus to handle the descending and ascending of the drill pipes in the operation of well-repairing in oilfield.
With reasonable design,easy operation,safety and reliability and qualified materials, T-Brand CDQ(S) Sucker Rod Elevators series are manufactured by both advanced technology and special intensity heat treatment. They are verified with super structural and wear-resisting nature by strict strength test and NDT. They can handle sucker rods of 5/8in-1 1/4in diameter used in the operation of descending and ascending.
All the technical parameter and property of the elevators completely conform to the requirements of SY5235 and API Spec 8A.
2. Structural
CDQ(S) Sucker Rod Elevators series are tongue-and-spring type elevators which consist of elevator segment, handle, and so on.
The front and back tongues which can rotary around the bolt are fit in the body of elevator segment, each of the front and back tongues is fitted with one wrench spring. When it is used in lifting, the front and back tongues move into the body of elevator segment with contact strength of the suck rod. When the suck rod is in the center hole of the elevator, the front and back tongues move back to their original position by the force of wrench spring to fix the suck rod lest the suck rod could separate from the elevator. When the two back tongues are pressed against each other, the two front tongues can swiftly move into the elevator segment, and then the suck rod can be discharged.
