A portable suspended scaffold utilizes a carriage having circumferentially grooved rollers which engage upturned flanges on a set of purlins. A suspension structure depends from the carriage such that workers may affix overhead fixtures such as roof panels to the purlins above the scaffold. The scaffold utilizes a plurality of platform elements which are removably carried by the suspension structure such that the scaffold may be manually propelled along the length of the purlin without having the workers thereon dismount.
