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.

摘要: A mast assembly for a drilling rig includes a mast formed from a plurality of mast subunits. The mast assembly includes a lower drilling machine, upper drilling machine, and upper mud assembly, each of which is coupled to and movable vertically relative to the mast. The mast subunits are separable when the mast is in a transport configuration such that the LDM is positioned in a first subunit and the UDM is in a second subunit of the mast when the mast is in the transport configuration. The mast assembly may be used during a continuous drilling operation.
