ABSTRACT:
A self-propelled truck has a rotatable turret on which an articulated and nested assembly of frame members and a scaffold is mounted for transport. The turret and assembly can be operated to place the frame members in position to define a vertically extending portion outwardly of one side of the truck to extend, for example, downwardly of the side of a bridge on which the truck is located. The scaffold then extends horizontally from the lower end of the vertical portion and may be swung horizontally to extend either parallel to the side of the bridge or to extend inwardly under the bridge. The scaffold is also vertically movable and wheeled stabilizers on the truck can hold the same against tilting while permitting movement of the truck across the bridge with the assembly extended as described.
