Abstract
A universal hoist assembly for lifting large, heavy, structures. The assembly basically includes a housing which captures the base of a lift swivel while permitting free rotation of the base. An upright extension of the base extends out of the housing and has a transverse aperture through which a shackle is fastened. This arrangement permits the shackle to pivot and the extension to freely rotate, so that a lift can be conducted with structures of widely varying configurations without danger from sideloads on the lift assembly. Preferably, the base is either disk-shaped and housed in a corresponding recess for rotation in a plane or has a spherical exterior shape in a corresponding recess to permit rotation plus pivoting in any direction. The assembly may be fastened to a structure by a single central threaded bolt fastened to the housing and threaded into the structure or extending through a structure wall to a nut or by several spaced bolts. Two housings may be secured to a structure in a spaced relationship with a single shaft extending through apertures at the housings and a shackle on the shaft intermediate the housings.
