摘要： A wrench assembly comprises upper and lower clamp assemblies each having a plurality of grip assemblies, a plurality of torqueing cylinders, and a hydraulic circuit. The hydraulic circuit is in fluid communication with the grip assemblies and the torqueing cylinders and is configured to control a gripping force applied by the grip assemblies relative to a torqueing force applied by the torqueing cylinders. The hydraulic circuit is configured to maintain the gripping force in a proportional relationship with the torqueing force.

摘要： 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.

摘要： 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.

摘要： A safety system for bypassing counter balance valves of a catwalk hydraulic cylinder from a remote location in a safe and controlled manner. Oil from a base end of the hydraulic cylinder is routed around the counter balance valves and flows through a velocity fuse to a needle valve, a check valve, and a pump outlet.

摘要： In one embodiment, a skate configured to engage a tubular while moving along a catwalk trough is provided. The skate comprises a frame having a drive system configured to move the tubular along the catwalk trough, a grip device coupled to the frame and configured to grip a pin end of the tubular, and a controller in communication with the drive system that controls movement of the frame based on movement of a box end of the tubular.

摘要： 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.

摘要： In one embodiment, a traverse system configured to move a catwalk relative to a beam, is provided. The system includes a body, an upper brake pad coupled to the body and configured to contact a side of a flange of the beam and a lower brake pad coupled to the body and configured to contact an opposing side of the flange, and an actuator coupled to at least one of the brake pads and configured to move the brake pads between a gripping position that grips the flange and an open position that spaces one of the brake pads away from the flange.
