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.

A strander apparatus includes a disk and a plurality of cradles, each of the cradles includes a reel and a cradle shaft, the cradle shaft extending in an axial direction from the disk. Each reel dispenses cable. The strander includes a main shaft, wherein the cradles are disposed on the cradle shafts radially about the main shaft. Planetary gears are disposed between the main shaft and the plurality of cradle shafts. The strander operates in one of a planetary mode and a rigid mode. In the planetary mode, while the main shaft rotates, the planetary gears are engaged to rotate each of the plurality of cradles on the respective cradle shafts. In the rigid mode, the planetary gears are disengaged.

Provided is an apparatus for tightening wire, comprising: a housing (10); a spool (20) mounted to the housing to wind a wire; a winder (30) that engages with the spool to wind the wire or disengages from the same to unwind the wire; a ratchet (40) that allows axial rotation in one direction in which the wire is tightened; a spiral cam (50) where the winder and the ratchet are mounted; and a dial (60) mounted to the spiral cam to axially rotate the winder. The apparatus provides an engagement and disengagement structure that allows the spool and the winder to engage or disengage, so that, by forward and backward rotations, only the wire is wound when the spool and the winder engage and the wire is unwound when the spool and the winder disengage, thereby allowing the winding and unwinding of the wire by simple forward and backward rotating operation.
