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 pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.

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.

Abstract: An apparatus for installing multiple strands of hose below a surface of terrain is provided. The apparatus comprises a chassis and rotating trenching blade assemblies connected to the chassis. The trenching blade assemblies are configured to dig parallel trenches when the apparatus is pulled along the terrain. Curved hose guides are connected to the chassis in trailing positions behind the trenching blades. Each hose guide receives hose from a hose reel on reel mounts connected to the chassis and deposits the hose into a trench dug by a trenching blade assembly. Trench fillers connected to the chassis trail the hose guides. Each trench filler is aligned with a respective hose guide and comprises a number of blades configured to push soil excavated from a trench back into the trench when the apparatus is pulled along the terrain.

Abstract: A method for breaking the friction between a buried pipe section and its surrounding soil. A linear actuator or a pneumatic impact mole pushes on one end of the pipe section while a pipe extractor pulls on the opposing end of the pipe section. In an alternative embodiment, a device is used to excite the pipe section's natural vibrational frequency while a pipe extractor pulls on one end of the pipe section. After the friction between the pipe section and its surrounding soil is broken, the pipe extractor may remove the pipe section from its borehole. In another embodiment, the pipe section may be cut into smaller sections and each section may be individually removed from the ground using a pipe extractor. Alternatively, the smaller pipe sections may be individually loosened from the surrounding soil and then rejoined before being removed from the ground by a pipe extractor.
