A rail support system (10) pendent from an overhead structure is configured for supporting lifting, and conveying material, machinery, and equipment from one location to another, and for supporting movable trolleys and traveling cranes. The rail support system (10) includes a plurality of side rail members (12); wherein the side rail members (12) are disposed in opposed pairs in uniform parallel alignment thereby forming a runway section with one or more runway sections (76) disposed in successive end-to-end relationship to form a runway track. The alignments of the opposed pairs of side rail members (12) are maintained by spacers (26) and clamps (40) that are disposed between and interconnect the side rail member pairs. Trolley vehicles (60) travel in v-shaped track guides of the side rail members (12), and adjacent side rail members (12) forming each half of the runway sections (76) are secured together by joint plates (82) that prevent the separation of the adjacent side rail members (12).
