ABSTRACT:
Transfer table for storage and lateral transport of elongated structural members, such as I-beams, having 1/4 inch or greater flanges. The table includes a plurality of longitudinally extending stationary supports defining a lateral carriage for the I-beam flanges. Individual roller carriages are reciprocally supported within at least two adjacent supports, each roller carriage having a plurality of longitudinally extending trains of idler rollers, staggered upon transverse axes atop the carriage. Each roller carriage includes an expansible mid-section, so as to lift the idler rollers and the I-beams supported thereon above the level of the longitudinally extending stationary supports. A conveyor drive attached to each roller carriage then propels the roller carriage and I-beams supported thereon across the transfer table to an axial conveyance.
