ABSTRACT:
A telescoping wall scaffold has a suspension member with a first end and a second end and shaped therebetween to extend about the overhang of a structure having a vertical surface. A leg and foot arrangement is attached to the first end for contact with the structure. A base member is attached to the second end to extend downwardly therefrom along the surface of the structure. At least one telescoping member is mechanically and telescopically adapted to the base member for telescopic movement and relation thereto. A platform support is attached to the telescoping member to support one or more platforms. A spacer member is also adapted to the telescoping member to extend away therefrom toward the surface of the structure. A wheel or roller is adapted to the spacer member for rolling contact with the surface. A winch with a reel having a rope wound thereon is also secured to the telescoping member. One end of the rope is secured to the scaffold proximate the suspension means so that upon operation of the winch means the telescoping member selectively raises and lowers along the surface.
