  • Patent number: 11428056
    Abstract: A pipe puller removably couples to a pipe handler skate using two manually removable pins. The pipe puller includes at least one slide and linear bearing combination, a skate plate affixed adjacent a first end of the slide and interposed between a front skate face and a pipe in the skidway, a pipe grasp pivotal between a first position disengaged from the pipe and a second position engaged with the pipe, linkage coupling the skate plate to pipe grasp and converting reciprocal movement of the skate plate into rotary movement of the pipe grasp, and a puller stop bracket secured to the pipe handler. A pair of force threshold activated pipe grasp assists retain the pipe grasp in either pipe-engaged or pipe-disengaged position until a force threshold is reached greater than and separate from the static and dynamic coefficients of friction of the various pintles and linear bearings.
