A mobile suspended scaffold arrangement comprises a support portion which can move along rails or purlins provided on the roof of a steel building, a boom assembly extending outwardly therefrom and a scaffold hanger portion suspended from the boom assembly. The device is particularly for use in cladding prefabricated steel buildings. The wheel assemblies include a vertical support wheel and a horizontal guide wheel and can be coupled by simple elongate beams extending at right angles to the rails. The support portion on the roof can be divided into two separate dollies which can be used for transporting equipment on the roof. The support portion couples to the hanger portion both at a hook at the top of the beam and also at a bracket extending outwardly from one side of the support so as to clamp the hanger rigidly vertical to prevent twisting.
