PROJECT DESCRIPTION

Sucker Rod Elevator series are tongue-and-spring type elevators which consist of elevator segment,handle, and so on. They are hoisting tools for handling sucker rods

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 the suck rod can be discharged.
