A mobile elevating scaffold includes an elongated scaffold platform or walkway which is supported by a scaffold frame structure which can be raised or lowered within a fixed upright frame structure mounted on a truck chassis. Movement of the scaffold frame structure is effected by first and second cables extending from winch drums mounted on the chassis and over first and second primary cable pulleys and terminally connected to the scaffold frame structure to provide a two-point suspension for that structure. The scaffold platform or walkway is usefully longitudinally adjustably supported on arms extending transversely outwardly from the scaffold frame structure.
