ABSTRACT:
A scaffolding system for performing a work such as repair, coating or tiling on an outer wall surface of a building, chimney, petroleum tank or the like comprises parapet wall hooks provided on the top portion of a building, hanging stages suspended from the parapet wall hooks by means of first cables and arranged in horizontal alignment with one another, protective nets which can be stretched between the parapet wall hooks and the hanging stages, and means for lifting and lowering the protective nets by means of second cables secured to the protective nets. The protective nets can be lifted or lowered as desired regardless of position of the hanging stages and without lifting or lowering the hanging stages. The protective nets can be readily lowered and stored in the hanging stages when a strong wind is expected whereby damage to the protective nets due to wind can be prevented.
