Modular enclosure transfer system including rollers
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.
1. 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;
wherein the roller body is connected to a beam guide comprising a beam guide plate; and
wherein the beam guide comprises upper flange rollers joined by an upper rod running axially through each upper flange roller, lower flange rollers joined by a lower rod running axially through each lower flange roller, and a flange roller connector connected to the beam guide plate and connecting the upper rod to the lower rod.
2. The pre-fabricated enclosure transfer system of claim 1 , wherein the flange roller connector is sized such that the upper flange rollers roll on the top of an uppermost horizontal flange of the beam and the lower flange rollers roll on the bottom of the uppermost horizontal flange of the beam.
3. The pre-fabricated enclosure transfer system of claim 1 , wherein side rollers are connected to the beam guide plate by side roller rods.
4. The pre-fabricated enclosure transfer system of claim 1 , wherein a rotatable connection plate is rotatably attached to the roller body.
5. The pre-fabricated enclosure transfer system of claim 4 , wherein the rotatable connection plate comprises a grip for connection to a pre-fabricated enclosure.
6. The pre-fabricated enclosure transfer system of claim 1 , further comprising a U-shaped crib.
7. The pre-fabricated enclosure transfer system of claim 6 , wherein each U-shaped crib comprises layers and a metal plate.
8. The pre-fabricated enclosure transfer system of claim 7 , wherein each U-shaped crib comprises a metal plate between each layer and a metal plate on top of the uppermost layer.
