A rotation unit for a torque tong for making and/or breaking threaded connections between pipes and/or spinning pipes during screwing and/or unscrewing of pipes, primarily pipes used in petroleum production. The unit includes a fixed part and a rotary part arranged to grip a pipe to be rotated. The rotary part includes at least one movable gripping jaw arranged to be moved into engagement with the pipe. The fixed part includes at least one gripping cylinder arranged to move the gripping jaw to engage the pipe when the gripping jaw is operatively engaged with the gripping cylinder.

Rotation unit for torque tong comprising a gripping cylinder

A rotation unit for a torque tong for making and/or breaking threaded connections between pipes and/or spinning pipes during screwing and/or unscrewing of pipes, primarily pipes used in petroleum production. The unit includes a fixed part and a rotary part arranged to grip a pipe to be rotated. The rotary part includes at least one movable gripping jaw arranged to be moved into engagement with the pipe. The rotary part includes toothing arranged to engage at least one chain, which is operatively connected to an actuator in order to move the chain and so impart rotary movement to the rotary part.

Rotation unit for torque tong comprising a rotational part with teeth

A device for handling pipes or stands including a transportation carriage for transport of pipes or stands between a pipe storage and a place for use. The carriage includes picking columns, each having a first picking arm arranged to move substantially vertically. The arms are capable of lifting at least one horizontal pipe or stand from the pipe storage. The picking columns are also equipped with a respective second picking arm, capable of motion substantially vertically on the opposite side of the picking column, to hold the pipe or stand between the first and second picking arms. Also described are a storage device and a pipe erecting device to be used together with the transportation carriage.

Horizontal pipe handling device

A pipe handling apparatus is disclosed, which is adapted for automated drilling operations. Drill pipes are manipulated between substantially horizontal and vertical positions, and the apparatus is used with a top mounted drilling device which is rotatable about a substantially horizontal axis. The apparatus comprises a strongback provided with clamps to hold and manipulate pipes. The strongback is at one end portion rotatably connected to the same axis as the drilling device. The strongback moves up or down with the drilling device. A brace unit is attached to the strongback to be rotatable about a second axis spaced apart from said first axis. The brace unit has one end portion rotatable about a third axis.
