Abstract
Abstract A method and apparatus for erecting a home or building from prefabricated building sections wherein a prefabricated house or building section is transported on a carrier over a highway to a building site alongside a foundation, and removing the prefabricated building section from the transporting carrier and setting it onto the permanent foundation by means of a pair of substantially vertically positionable A-frame hoists rollable on parallel tracks made from portable interfitting sections which extend from along the ends of the carrier to along and closely adjacent the ends of the foundation. Each of these A-frame hoists have means for engaging opposite ends of the house or building section and lifting it from the carrier, moving it along the tracks to the foundation and setting it down thereon. The house section engaging means of one of the A-frames is freely suspended from the apex thereof by a hoist means, and the engaging means of the other A-frame is vertically movable along a vertical bar suspended from the apex of its A-frame, the lower end of which bar is guided, restricted, and transversely movable in its pendular movement relative to the A-frame.
