  • Publication number: 20090184079
    Abstract: A heavy duty hoist for use in lifting and transporting stacked concrete forms and the like has a main body with a vertically extending guideway which receives an operating slide. Rigid arms extend in opposite directions at the bottom of the body with pivot pins at their outer ends. A second pair of arms extend from the slide to the pivot pins and carry sleeves engageable with the pins for pivotal movement with vertical movement by the slide. Rigid outer sections of the second pair of arms depend from the inner sections and carry inwardly projecting lifting elements at their lower end portions for engagement beneath a stack of forms. The slide carries a pair of rollers above and below the inner end portion of each of the free end portions of the second pair of arms with slight longitudinal relative movement thus accommodated. A lifting device in the form of a simple eye-member is mounted on the slide.
