A hoist assembly 10 for lifting an object 12 includes a support fixture 14 having three elongated support rails or members 16, 18, and 20, a movable lever assembly 24, which is mounted upon a spanning member 22, and three interconnecting chains, members or assemblies 26, 28, and 30 which are coupled to fixture 14 and to object 12. Movable lever assembly 24 moves from a first position to a second position when object 12 is lifted, thereby shifting the center of gravity 142 of the fixture 14 and allowing fixture 14 and object 12 to remain in a level or horizontal position.
