A roller on the front of the truck is raised or lowered by an extensible motor controlled by the tong operator to align the pin end of the joint to be made up with the collar of the made up pipeline. The operator manipulates the support to position the casing tongs over a pipeline joint to be made up and rotates the tong dies to rotate the pipeline joint.Field of SearchWith forming or cutting of pipe or cableAdvancing subterranean length of pipe or cable Underwater docking or mooring With assembling of line structure By joining successive sections of line By control of buoyancy MISCELLANEOUS By means advancing along terrain and guiding pipe or cable into subterranean position Pivoted jaw HOIST-LINE SLINGS Coupling to conduit Of separate helix (e.g., screw thread) LOAD BRIDGING VEHICLE Pipe laying Vehicle having supporting wheel or wheel substitute Side boom supported hoist line Vehicle | |
