A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

A pipe racking system including two mechanical arms to move pipe stands to a dedicated position on a rig floor wherein at least one mechanical arm is connected to a mast of a drilling rig. A method to move a drilling rig comprising: providing a pipe racking system with two mechanical arms connected to the mast of the drilling rig; folding the pipe racking system onto the mast of the drilling rig; and transporting the drilling rig without disassembling the pipe racking system from the mast.

Pipe handling system and method

Embodiments of a vertical pipe handler system () and method of its use include a casing tong handling tool () connected to a lifting tool () having a gripper head () and supported by an arm () of the vertical pipe handler system. The casing tong connection () of the handling tool is located toward the tool's lower end () and may be offset in a horizontal direction from the connection () to the lifting tool. The casing tong () then hangs off-center relative to the lifting tool. The amount of offset may be effective to prevent interference between the gripper head and a tubular being handled by the casing tong.
