Abstract
A pole puller system comprising a base plate, a slide tube, and a slide. The system further comprises a hydraulic cylinder, a hydraulic fluid pump, and a pair of hydraulic hoses. There is also provided a means for coupling a pole to be pulled to the slide.
Claims14
A pole puller system comprising, in combination:
- a base plate having a generally rectangular configuration with a concavely shaped side, the base plate having a mounting portion comprising a tab for coupling a hydraulic cylinder thereto, with the tab having a mounting pin hole there through;
- a slide tube being operatively coupled to the base plate, the slide tube having an outer surface;
- a slide having a generally hollow cross-sectional tubular configuration, the slide having an inner surface, the slide being coupled to the slide tube with inner surface of the slide being slidably moved along the outer surface of the slide tube, the slide having a hydraulic cylinder mounting tab with a mounting aperture there through;
- a hydraulic cylinder having a ram, the hydraulic cylinder coupling the base plate tab and the slide tab;
- a hydraulic fluid pump;
- a pair of hydraulic hoses operatively coupling the hydraulic fluid pump and the hydraulic cylinder;
- a means for coupling the system to a pole to be pulled;
- and
- a boom truck having a boom, the boom being configured to lift the pole puller and position the pole puller near a pole to be pulled, the pole having a free weight, the boom being used lift the free weight of the pole.

A pole pulling system comprising, in combination:
- a rigid base plate having a generally rectangular configuration having a flat planar lower surface and an upper surface, the base plate having a concave shaped portion of the edge to accommodate placement next to the pole to be pulled;
- a slide tube having a generally rectangular tubular configuration having an exterior cross sectional diameter of a first diameter and an outer surface, the slide tube being operatively coupled to the base plate;
- a slide having a passageway there through, the slide having an inner surface, the passageway having a second interior cross sectional diameter, the second diameter being greater than the first diameter, the slide being slidably coupled to the slide tube with inner surface of the slide being slidably moved along the outer surface of the slide tube, the slide having a hydraulic cylinder mounting tab with a mounting aperture there through;
- a hydraulic cylinder having a movable ram coupling the base plate and the slide;
- a hydraulic fluid pump having a hydraulic fluid reservoir and a fluid control valve;
- at least one hydraulic hose operatively coupling the hydraulic fluid pump and the hydraulic cylinder;
- a boom truck having a boom and attachment means for positioning the system relative to a pole to be pulled, the boom truck providing a lifting force to lift the free weight of the pole to be pulled;
- a means for coupling the system to a pole to be pulled to the slide.
