Abstract: A stand for support of a structure, as a mobile home, above the ground. The stand includes a generally flat base and a plurality of legs having lower ends pivotally assembled to the base. The legs extend in upwardly converging relationship away from the base and are pivotally connected at the upper ends to a support platform. The lower ends of the legs are movable on the base in such a fashion to raise and lower the support platform. Means are provided to secure the position of the lower ends of the legs to the base whereby the support platform may be positioned in firm, supportive relationship to the structure.

Abstract: A modular building unit jacking system includes a modular building constructed for attaching and supporting special jacks. The jacks can be quickly inserted into a perimeter frame of the modular building unit, and the building unit lifted to a predetermined height where a truck trailer bed can be backed under it. The unit lowered onto the trailer bed. The jacks have an elongated support arm for insertion into an opening in the perimeter frame of the building. The perimeter frame has vertical support columns therein, so that the force from the jack in lifting the building is spread in the perimeter frame and directed into the vertical columns.

Abstract: A trailer jack foot for use with a trailer jack having a vertically extending housing and an extensible member, the trailer jack foot comprising a horizontally extending flange on the housing, a horizontally extending flange on the lower end portion of the extensible member, and a jack extender attachable to the flange on the extension member to extend the effective length of the jack, and, alternately, to the flange on the housing for storage.
