Abstract
A pole extractor having a base and a hydraulically operable cylinder and ram assembly. The base is coupled to an attachment means to define a slot for accepting a mobile positioning device. The cylinder and ram assembly have a proximal end coupling said assembly to the base. The ram has a distal end remote from the base, which has a connecting means to accept a holding means. In use, the holding means releasably holds a pole. The cylinder and ram assembly has a fluid inlet and a fluid outlet to communicate with an actuating means that controls extension of the ram within the cylinder, which in turn extracts the pole. In use, a pole is choked to the ram and the ram is actuated in order to extract the pole from a substrate.
Claims11
A pole extractor having a base and a hydraulically operable cylinder and ram assembly, said base being coupled to an attachment means which extends over the base and is spaced from the base by a lip to define a slot for receiving a piece of heavy equipment between an upper surface of the slot and a lower surface of the slot, the attachment means defining the upper surface of the slot end the base defining the lower surface of the slot;
- said cylinder and ram assembly having a proximal end coupling said assembly to the base, a ram having a distal end remote from the base, said distal end having connecting means to accept a holding means that in use, releasably holds a pole, whereby, upon extension of the ram within the cylinder and ram assembly, the pole is extracted.
A pole extractor having a base and a hydraulically operable cylinder and ram assembly, said base being coupled to an attachment means, said base having:
- base holes to retain fastening means such that in use, the extractor is releasably fastened to a piece of heavy equipment;
- a U-shaped rest mounted on the base to receive the cylinder and ram assembly for stabilizing said assembly during transit;
- at least one support member to removably couple the base to the mobile positioning device, thereby further affixing and locating the extractor;
- and
- at least two channels mounted on the base to receive fork lift forks for moving and positioning the pole extractor with a forklift,
- said attachment means comprising a lip, a plurality of extension bars and fastening means, said extension bars being spaced from the base by a lip and extending at least partially over the base to define a slot for accepting the piece of heavy equipment,
- said cylinder and ram assembly having:
- a proximal end coupling said assembly to the base;
- a ram having a distal end remote from the base, said distal end having connecting means, said connecting means being removably disposed on the distal end of the ram and having holding means that in use, releasably holds a pole;
- and
- at least one rocker foot to pivotally couple a proximal end of the cylinder and ram assembly to the base;
- wherein said cylinder and ram assembly is reciprocally fluid powered to control extension of the ram within the cylinder and ram assembly, whereby a pole is extracted.
A pole extractor having a base and a hydraulically operable cylinder and ram assembly, said base being coupled to an attachment means comprising at least one extension bar extending over the base and spaced from the base by a lip to define a slot for accepting a piece of heavy equipment,
- said cylinder and ram assembly having a proximal end coupling said assembly to the base, a ram having a distal end remote from the base, said distal end having connecting means to accept a holding means that in use, releasably holds a pole, whereby, upon extension of the ram within the cylinder and ram assembly, the pole is extracted.
