Abstract

The Brazilian Regulatory Standard 18 (NR 18) requests that the manual work on roofs must be made with the use of devices sized by legally qualified professionals to allow safe movement of workers. The safer form of locomotion during working on roofs are traditionally obtained by the use of walkways or platforms, which must be properly fixed to the roofing structure. In this work, it were dimensioned and fabricated aluminum components for mechanical fixing of aluminum. These components have been properly welded to the platforms ladder to obtain a safer final product as well suitable for roofing maintenance, especially in metal sheds of major proportions, as was the case of the warehouses where the product was first used.
