Slide and lower modular enclosure transfer system
A non-crane system for moving a pre-fabricated enclosure is disclosed. The system comprises a sliding beam system and a system of coordinated self-contained hydraulic jack units, which in conjunction allow a pre-fabricated enclosure to be slid horizontally off a semi-trailer, positioned above a pre-laid foundation, and lowered to the foundation. Slide beams are arranged perpendicularly to the semi-trailer and supported by blocks at the height of the pre-fabricated enclosure. A cable attachment plate located on each slide beam connects to the pre-fabricated enclosure and is connected by a cable to winches placed at the end of each slide beam. The rotation of the winches pulls the pre-fabricated enclosure off the semi-trailer and onto the sliding beam system. The system of coordinated self-contained hydraulic jack units, which comprises multiple portable self-contained hydraulic jack units, then lowers the pre-fabricated enclosure to the foundation.

connecting each winch to a generator.
4. The method of claim 3 , wherein assembling the sliding beam system further comprises:
providing a lubricious surface on a top of each slide beam.
5. The method of claim 3 , wherein assembling the sliding beam system further comprises positioning a blanket over each cable.
6. The method of claim 3 , wherein assembling the sliding beam system further comprises placing a tongue of a slide beam on the semi-trailer.
7. 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;
parking the semi-trailer next to a pre-laid foundation;
assembling a sliding beam system;
moving the pre-fabricated enclosure from the semi-trailer on to and across the sliding beam system;
supporting the pre-fabricated enclosure with the system of coordinated self-contained hydraulic jack units;
removing the sliding beam system; and
lowering the pre-fabricated enclosure to the foundation,
wherein attaching a system of coordinated self-contained hydraulic jack units to the pre-fabricated enclosure further comprises:
wheeling a plurality of self-contained hydraulic jack units in tipped positions to be adjacent to the semi-trailer;
setting a base of each self-contained hydraulic jack unit on the ground or on a block and righting each self-contained hydraulic jack unit into an upright position;
extending a cylinder of each self-contained hydraulic jack unit until a connecting plate of each self-contained hydraulic jack unit is at the same height as the pre-fabricated enclosure;
fastening the connecting plate of each self-contained hydraulic jack unit to the pre-fabricated enclosure, wherein fastening the connecting plate of each self-contained hydraulic jack unit to the pre-fabricated enclosure includes bolting the connecting plate to a vertical web of an C-channel of a frame defining a base of the pre-fabricated enclosure.
8. A method of transferring a pre-fabricated enclosure, comprising:
placing a pre-fabricated enclosure on a semi-trailer;
