Elevator for lifting tubulars of various sizes, the elevator having a locking mechanism

Abstract

A system including an elevator to move a tubular, the elevator including two or more remotely operable latches that can configure the elevator to handle various tubular diameters. Each jaw can include a locking mechanism that engages a portion of the housing adjacent a spacer ring in the elevator when the first jaw is in the engaged position and configured to transfer a closing force to the housing. A portion of the latches can be laterally offset from each other and another portion can overlap adjacent latches. The elevator can be explosive (EX) Zone 1 certified with an electronics enclosure contained within a sealed chamber. The elevator can use rotary actuators to operate the latches and rotate the housing of the elevator. The elevator can use a circular pressure sensor to determine weight of a tubular.
