A machine-liftable, open-framework, cage-like transporter for lifting and maneuvering horizontal structural beam elements, and the like, to appropriate installation elevations at and from the side of a plural-story building frame which is under construction. The transporter acts as a building-frame construction aid in the form of a worker-carrying, liftable, open-cage transporter including a volume-defining cage in which one or more worker(s) can station and ride, with this transporter possessing an overhead, fully exposed-from-below, support deck on which structural frame components, such as beam components, can be placed and supported in horizontal dispositions for lifting by the transporter to the appropriate elevation(s) in an emerging building frame which is being assembled. The open, overhead framework of the transporter promotes easy conveyance of such beam components to appropriate heights for delivery, precision aligning, locating, positioning and assembly within a building frame. It also offers special construction efficiency by allowing a worker, or workers, who are "inside" the cage of the transporter to reach upwardly from within the cage, through the open, overhead framework of the support deck, thus to contribute and assist in the off-loading and precision handling of transported components.
