Abstract: A cable pulling system and associated method are shown. Examples include positioning joints that allows a pulling boom to move up or down and side to side, while maintaining alignment of a pulling cable between pulleys. Example methods include positioning a pulling boom within a conduit box and pulling an electrical cable through a conduit into the conduit box.

Abstract: A pipe puller system and methods of pipe extraction are shown. In one example a pipe to be replaced is pulled by attaching a pulling force to multiple locations along a length of the pipe. In one example pulling forces can be varied between different attachment locations to better control or eliminate tearing of the pipe. In one example, a pipe loosening device may be used prior to pulling the pipe from the ground.

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 directional drill securing device and associated methods are shown. Securing devices and methods shown include a plurality of staking devices on a single lateral side of a directional drill. Using examples shown, a lower force is required to drive multiple staking devices than would be needed for a larger staking device of equivalent area.
