  • Patent number: 5555953
    Abstract: A scaffolding system which is attached to a prime mover such as a front end loader or forklift and has "Wings" or platforms extending outward from a "Center Frame" or platform and rotating in relation to it. The surface of the "Wings" upon which workmen stand is made up of individual steps. The tread of each step remains in a horizontal position during "Wing" rotation by using the principle of parallel arms. The "Center Frame" or platform can rotate in relation to a "Base Frame" to level the working surface despite the prime mover sitting on a sloping surface. All working surfaces are equipped with necessary guard rails. Hydraulic controls and emergency shut down switches are located for safe operation by all workmen.
