摘要:
Aspects of the disclosure relate to elevator locking system apparatus and methods, and associated components thereof. In one implementation, a slip-type elevator assembly includes an elevator body including one or more slips configured to grip a tubular, and a first door pivotably coupled to the elevator body. The slip-type elevator assembly includes a second door pivotably coupled to the elevator body, the first door and the second door movable between an open position and a closed position. The slip-type elevator assembly also includes a locking system including a bolt movable between an unlocked position and a locked position. In the unlocked position the bolt is disposed in a first cavity formed in the first door. In the locked position a first portion of the bolt is disposed in the first cavity and a second portion of the bolt is disposed outside of the first cavity.
