ABSTRACT:
A portable equipment handling apparatus comprises a track assembly that can be laid out in any desired configuration throughout a manufacturing plant, on a construction site or other desired facility. A movable platform is mounted on the track assembly and receives the equipment or supplies that are to be moved through the facility from an old location to a new location. The tugger puller is secured at the new location and the movable platform is loaded with the equipment or supplies at the old location. The activation of the tugger puller pulls the movable platform from the old location, along the track assembly, to the new location at which the equipment or supplies can be offloaded from the movable platform, if desired. The track assembly can include straight and curved segments to allow the track to be laid out in the desired path. The track can be disposed along floors, up and down stairs, along vertical walls and across ceilings. The joints between segments of the track assembly are two-way joints allowing the track assembly to bend either acutely or obtusely. The movable platform is provided with rollers designed to cooperate with the track cross section to mitigate the movable platform disengaging from the track during use. The movable platform also includes a braking device of the "dead man" type in the event of malfunction and to prevent inadvertent movement of the platform.
