Скачать или смотреть Vertical Pipe Racker/Handler vs. Top Drive

Pipe Racker Wins!!

The vertical pipe handling system rackers are advanced pipe handling systems for jackup rigs, semisubmersible rigs, and drillships. They perform all vertical pipe handling operations on the drill floor, including racking stands, building stands in the mousehole, picking up singles from the catwalk, laying out singles to the catwalk, and tripping in and out of the fingerboard.

A top drive is a mechanical device on a drilling rig that provides clockwise torque to the drill string to drill a borehole. It is an alternative to the rotary table and kelly drive. It is located at the swivel's place below the traveling block and moves vertically up and down the derrick.
