Abstract
A polished rod elevator has a top lift platform defining a polished rod passage and a mouth to laterally receive a polished rod into the polished rod passage; a plurality of linear actuators depending below the top lift platform and radially spaced from an axis of the polished rod passage to define a production tree receiving gap; and a plurality of arcuate wellhead flange mounting base plates connected to base ends of the plurality of linear actuators. Related methods of use and kits are discussed.
Claims21
A polished rod elevator comprising:
- a top lift platform defining a polished rod passage and a mouth to laterally receive a polished rod into the polished rod passage;
- a plurality of linear actuators depending below the top lift platform and radially spaced from an axis of the polished rod passage to define a production tree receiving gap;
- and
- a plurality of arcuate wellhead flange mounting base plates connected to base ends of the plurality of linear actuators.

A method comprising:
- arranging a polished rod elevator on a wellhead, such that:
- arcuate flange mounting base plates seat upon a flange of the wellhead,
- linear actuators extend upward from each arcuate flange mounting base plate, and
- a top lift platform mounts to respective top ends of the plurality of linear actuators, with a polished rod extending out of a production tree on the wellhead and through a polished rod passage defined in the top lift platform;
- and
- extending the plurality of linear actuators to cause the top lift platform to one or more of lift or support the polished rod.
