    Abstract: This machine is designed for laying large-diameter pipe over rough terrain in extreme climates. For example, it was designed to lay 48'''' steel pipe from the Alaskan North Slope across the mountains to the Gulf of Alaska. An enclosed, elongated vehicle or house straddles the ditch in which (or piers on which) the pipe is to be laid. The house is supported at each of the corners by pillars in order to maintain the house level. The pipe is supported through the house on carriages which are free to float from side to side and up and down. Therefore, the pipe is constructed with all its bends and crooks over the support position and the house follows the ditch, providing a warm environment for the workmen. A deck section follows the carriages up and down so the workers have a platform which is always maintained at a fixed position relative to the pipe. As the vehicle moves forward out from under the pipe, the pipe is lowered by a series of trailing roller jacks. A sleeve surrounds the pipe as it leaves the vehicle so the temperature of the pipe is gradually changed from the relatively warm temperature to the frigid arctic temperature.

    Abstract: A cable puller and a related method of use are provided. The cable puller includes a frame, a winch mounted to the frame, a frame mount and one or more redirection pulleys that guide a cable. The mount is mountable to an arm of a piece of equipment, e.g., excavator, backhoe, loader, etc., and configured to allow manipulation and tilting of the frame to align the redirection pulley at a level and orientation relative to an underground tubing that is to be decommissioned and/or replaced. A deflection plate can be joined with the frame forward of the pulley to protect the pulley if the cable draws a portion of the underground tubing toward it. A splitting wedge can be joined to the frame to fracture underground tubing drawn toward the plate or pulley. Related methods of use also are provided.

    Abstract: A conduit guide for a conduit laying machine has an arcuate channel and at least two longitudinally spaced apart roller sets rotatably mounted in the channel. Each roller set has an upper bow roller and at least two longitudinally spaced apart lower flat rollers, each roller set having a roller gap between the upper and lower rollers. The arcuate path has a radius that is equal to or greater than a minimum bend radius for the conduit. At least one roller gap adjuster has at least one resilient biasing element that permits increasing the spacings of the roller gaps while biasing the spacings of the roller gaps toward fixed minimum spacings. The guide reduces damage and/or twisting of conduits during a conduit laying operation, especially when laying multiple conduits (e.g., triplex electrical cable) from the same conduit feed passage.
