Abstract: Aspects of the disclosure relate to seal assemblies, and associated components thereof, and methods of using the same for use in pressure containing bodies, such as choke valves. In one example, a sensor is used with the seal assemblies. In one implementation, a pressure containing body apparatus includes a pressure containing body including a central opening and a central axis extending through the central opening. The pressure containing body apparatus includes a sleeve disposed in the central opening of the pressure containing body. The pressure containing body apparatus includes an angled seal disposed about the sleeve at an angle relative to the central axis of the pressure containing body. The angle is greater than 0 degrees and less than 90 degrees.

Abstract: Aspects of the disclosure relate to locking assembly apparatus and methods for fluid ends, and associated components thereof. In one implementation, a locking assembly for fluid ends includes a first actuator and a second actuator disposed at least partially below the first actuator. The second actuator includes one or more coupling surfaces disposed in coupling engagement with one or more coupling surfaces of the first actuator. The locking assembly also includes a plurality of wedges disposed about the second actuator and movable between an unlocked position and a locked position.

Abstract: A traverse actuating and gripping system configured to move a catwalk relative to a support structure. The system includes a body, an upper gripping pad coupled to the body and configured to contact a side of a support member of the support structure, a lower gripping pad coupled to the body and configured to contact an opposing side of the support member, and an actuator coupled to at least one of the gripping pads and configured to move the gripping pads between a gripping position that grips the support member and an open position that spaces one of the gripping pads away from the support member.

Abstract: A kicker assembly for a tubular handling system has a moving member of a linear actuator that moves between a first position on a fixed member of the linear actuator and a second position on the fixed member. The moving member of the linear actuator is connected to a kicker shoe by one or more connecting members to move the kicker shoe from a retracted to an extended position to move a tubular out of the tubular handling system. The axis of the fixed member of the linear actuator runs substantially perpendicular to the motion of the kicker shoe.

Abstract: A skate drive and tubular clamping system for a catwalk. The system includes first and second actuators configured to move a skate and a clamp. The system includes a biasing device coupled to the skate and configured to bias the clamp between and open and clamped position based on a tension force between forces applied by the first and second actuators and a clamping threshold force. The first and second actuators may be flexibly coupled to the skate drive and tubular clamping system, such as by cables, and remotely mounted on a trough of the catwalk.

Abstract: Techniques for loading and/or unloading cargo. A vehicle platform is rotated so that it is positioned between front and rear tires of the vehicle. The platform is lowered to a height lower than a top of the front or rear tires. Cargo is loaded or unloaded using the lowered platform.
