FIELD: mechanical engineering; transportation facilities. SUBSTANCE: device has drive 1 and chain conveyor with hangers secured on chains. Lower runs 4 and upper runs 3 of chains pass over charge-discharge section 5, painting section 6 and workpiece drying section 7. Arranged along lower run of conveyor chain are guides, pressure sprockets 12, 13 and 14 and toothed rack. Fitted on charge-discharge section 5 for engagement with chain links is spring-loaded stop. Each hanger of chain conveyer is made in form of rotating detachable drum with detents and gear wheel. Detents are secured on drum generatrix.
