摘要：Apparatus for erecting a prefabricated section building having two mastscentered on either side of its foundation, the sections transported to loading areasadjacent and between each mast and the foundation. Cables connect the masts andsupport two independently operable trolleys between the masts, a hoist on each trolleyincluding a cable connects via a yoke to a section in the loading area and lifts samevertically from a truck therein to at least the story being assembled, and then moves ithorizontally to immediately above its ultimate location where it is lowered. A nearbyoperator, by remote control depending from the trolley, controls its movements toposition it precisely, such control being of winches connected to cables for moving thehoist and trolleys. This operator also communicates with the ground by telephone orradio. Each mast has three stays. To raise it, it is laid out horizontally with the cables andstays positioned. A vertical support is connected to the stay leading towards directionthe mast is raised. By pulling this support in a rotary downward motion, each mast israised and then secured. The mast's relative orientation with the building to be erected issuch that each section is maintained in desired geometric orientation commencing with
positioning of the truck delivering same until placed in the building, the only movementsbeing horizontal and vertical without movement fore and aft, twisting or turning exceptminor adjustments incident to its final correct positioning.
