    摘要: 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. A portion of the latches can be laterally offset from each other and another portion can overlap adjacent latches. The elevator can be Atmosphere Explosible (ATEX) certified or International Electrotechnical Commission for Explosive Atmospheres (IECEx) certified according to explosive (EX) Zone 1 requirements with an electronics enclosure contained within a sealed chamber. The elevator can be rotated greater than 90 degrees relative to a pair of links that support the elevator. The elevator can use rotary actuators to operate the latches and rotate the housing of the elevator.
