ABSTRACT:
A plurality of portable grandstand seating sections forming a grandstand are each provided with central ground-engaging wheels and footings, either of which being retractable and extendable for supporting each section alternately with the wheels and the central footings. A collapsible and extendable rear footing is also provided on each section. The sections are capable of being transported between grandstand and storage locations by towing them on the wheels with the rear footings collapsed. A first of such sections which forms an end section of the grandstand is lifted at the grandstand location and is shifted away from an adjoining section, the wheels are placed in a ground-engaging position, the rear footing is collapsed, the rearward end of the section is lowered relative to the wheels and the section is towed on the wheels while supporting the rearward end. The second and remaining sections are thereafter transported in succession to the storage location. When transporting the sections to the grandstand location, a section is rolled on the wheels while supporting its rearward end with the rear footing collapsed. The rearward end is raised at the grandstand location, the wheels are retracted or the central footing is extended and the rear footing is extended for supporting the section on both footings. It is then shifted into a predetermined position for commencing formation of the grandstand, and the remaining grandstand sections are transported in succession to the grandstand location with each being shifted in succession into abutting engagement with a side end of a previously transported section.
