Abstract
This invention relates generally to a method for making a deck for use in construction. In one embodiment, the method includes, but is not limited to, positioning a first box tube substantially parallel to a second box tube; attaching a plate to the first box tube and the second box tube, the plate extending between the first box tube and the second box tube; coupling a hydraulic cylinder to the plate; slidably inserting a first extension member at least partially into the first box tube; slidably inserting a second extension member at least partially into the second box tube, the first and second extension members having a beam extending therebetween; coupling the hydraulic cylinder to the beam; positioning a platform having one or more wheels on the plate and over the hydraulic cylinder such that the platform is rollable relative to the plate; attaching the platform to the beam such that the platform is operable to retractably extend beyond an edge of a floor of a building in conjunction with the first and second extension members in response to actuation of the at least one hydraulic cylinder; and forming a rectangular cuboid basket comprised of six faces with a connecting mecha…
