Abstract:
1. A method of depositing a load on a first construction platform fixedly secured to a floor of a multi-story building under construction, said first construction platform having a first deck located beneath at least one second construction platform fixedly secured to a higher floor, said second construction platform being a partly retractable construction platform comprising a stationary support structure projecting outwardly from an edge of the building to a predetermined maximum extent, and a movable deck mounted on said stationary support structure which may be extended as a cantilever therefrom beyond said predetermined maximum extent or retracted into substantial registration therewith, said first deck of said first construction platform being located directly beneath the movable deck of said at least one second construction platform when said movable deck is extended as a cantilever, and said load is supported by a crane rope above said movable deck when said movable deck is extended as a cantilever, the method comprises the steps of: (a) retracting said movable deck into substantial registration with said stationary support structure; and (b) lowering the crane rope such that said load passes said stationary support structure of said at least one second construction platform beyond said predetermined maximum extent without interference therewith and depositing the load on said first deck.
