Claims9
An apparatus for spreading objects, the apparatus comprising:
- a first elongated tube and a second elongated tube telescopically and slidably coupled to one another;
- a plurality of extensions, each of the plurality of extensions having an extension coupler and an extension tube, the extension coupler having an inner diameter larger than an inner diameter of the extension tube, wherein the extension coupler receives one of a distal end of the second elongated tube, or one of the plurality of extensions into the inner diameter of the extension coupler;
- a hydraulic jack coupled to a distal end of the first elongated tube;
- a jack shaft coupled to the hydraulic jack;
- a first shoe interchangeably coupled directly to a distal end of the jack shaft through a first shoe receiving recess, the first shoe being interchangeable with one of a plurality of accessories, wherein the plurality of accessories are coupled directly to the distal end of the jack shaft;
- and
- a second shoe interchangeably couplable in a static condition to a distal end of one of the plurality of extension tubes or the distal end of the second elongated tube, wherein the second shoe is interchangeable with one or more of the first shoe, or the plurality of accessories;
- wherein the jack shaft is configured to selectively increase a first spacing that is defined between the first shoe and the second shoe by actuating the jack shaft.
