ABSTRACT OF THE DISCLOSURE A link engaging pipe elevator is shown having link engaging arms and an automatic locking mechanism. Spring tension in the locking mechanism is overcome when the elevator body is rested on a substantially flat surface allowing unrestrained movement of the link engaging arms.

A cam and cam roller assist in moving the link engaging arms between the full open and closed positions.
