Abstract
A crane-free system for moving a pre-fabricated enclosure includes a beam system and a system of coordinated self-contained hydraulic jack units, which in conjunction allow a pre-fabricated enclosure to be lifted off a semi-trailer, positioned by rolling on the system of beams above a pre-laid foundation, and lowered to the foundation. Optionally, the sliding beam system may be rotated using rotatable rollers to allow the pre-fabricated enclosure to move in a rotated direction. Optionally, a centering device and hydraulic ram may be used to center the pre-fabricated enclosure on the foundation.
Claims22
A pre-fabricated enclosure transfer system, comprising:
- a beam system comprising a beam, a roller body, a cable, and a winch;
- a system of coordinated self-contained hydraulic jack units comprising a plurality of self-contained hydraulic jack units, each self-contained hydraulic jack unit comprising a pair of wheels, a base, a connecting plate, an actuable cylinder comprising a counterbalanced hydraulic valve system, and a power unit.
A method of transferring a pre-fabricated enclosure, comprising:
- placing a pre-fabricated enclosure on a semi-trailer;
- attaching a system of coordinated self-contained hydraulic jack units to the pre-fabricated enclosure;
- supporting the pre-fabricated enclosure with the system of coordinated self-contained hydraulic jack units;
- removing the semi-trailer out from underneath the pre-fabricated enclosure;
- assembling a beam system;
- moving the pre-fabricated enclosure across the beam system;
- removing the sliding beam system;
- and
- lowering the pre-fabricated enclosure to the foundation.
A centering device for centering a pre-fabricated enclosure on a foundation comprising:
- a central hub connected by spokes to a circular outer edge;
- downward prongs extending below the circular outer edge on a first side of the circular outer edge;
- upward prongs extending above the circular outer edge on a second side of the circular outer edge.
