Abstract

A conveyor comprises parallel side frames provided with a plurality of apertures and C-shaped cross members provided with apertures in the side walls disposed in juxtaposition to apertures in the side frames. The cross member apertures are each defined by a flat inner wall. The cross members are fastened to the side frames by hook-bolts having a hook portion extending through the side wall apertures and a shaft extending to a juxtaposed aperture in the side frame and provided with a nut and washer to secure the bolt in the side frame. The hook portion of the bolt is provided with a flat surface extending a substantial distance across the inner surface of the hook portion of the bolt to provide a load bearing contact area with the inner wall of the side member aperture. The cross members have tabs extending outwardly from each end which are inserted into complementary apertures in the side frames. The resulting bolted conveyor frame construction ensures frame alignment under heavy loads.
