ABSTRACT:
A parapet-mounted hoist made from an elongated cradle. The cradle is essentially a rectangular box-shaped mounting frame having two pairs of mounting frame legs secured to the parapet with cradle bolts. A steel square tubed safety brace mount is seated between an inside surface of the cradle's top frame, and the parapet wall. The safety brace mount has a back segment extending slightly beyond a rear plane of the mounting frame, and a forward segment extending slightly beyond a front plane of the mounting frame. The safety brace mount has a threaded safety brace pin penetrating its wall. An elongated steel safety brace having a proximal end positioned within the back segment of the safety brace mount. A boom mount having a vertically oriented cradle stub is disposed on the outside surface of the cradle. The cradle stub has a lower end affixed to the outside surface, and an upper end supporting two parallel, horizontal mounting plates. A boom and an integral boom coupling rotate about a vertical axis defined by a boom mounting bolt through the boom mount. The boom passes directly over the safety brace and the parapet at 90 degrees from its loading position and at 90 degrees from its unloading position.
