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.

Hydraulic lift and walking system for catwalk machine

A catwalk and crane system for transporting equipment of a well system includes a substructure, a directing frame pivotally coupled to the substructure, a pipe transporter configured to transport a tubular along the directing frame, a first actuator coupled to the directing frame and configured to rotate the directing frame relative to the substructure, and a crane coupled to the directing frame, wherein the crane is extendable from a first end of the directing frame.

Catwalk and crane system

A catwalk for transporting tubular members of a well system includes a substructure, a first transport frame pivotally coupled to the substructure at a first pivotal joint and including a first support surface configured to engage the tubular member, a second transport frame pivotally coupled to the first transport frame at a second pivotal joint and including a second support surface configured to engage the tubular member, and a strut pivotally coupled between the second transport frame and the substructure, wherein the strut is configured to transfer the weight of the tubular member from the second transport frame to the substructure when the tubular member is transported between the first support surface and the second support surface.

Pipe transport system and method

Systems and methods for vertical pipe handling include telescopic arm structures that move between retracted and extended positions in a horizontal plane, a cross arm structure connected to each telescopic arm structure, and a gripper head connected to the cross arm structure. The gripper head may be positioned at a desired location to receive, grip, position, and release a vertically oriented drill pipe or other tubular, and may include jaws that can be positioned to accommodate different sizes of drill pipe or tubulars. Means for raising and lower the gripper head, extending or retracting the gripper head in a horizontal plane, and tilting or pivoting the gripper head may also be provided. The vertical pipe handler may be housed below the drill floor and attached to the drill floor support structure.
