  • Patent number: 10843718
    Abstract: The construction industry ranks among the largest and most dangerous industries in the world. To promote worker safety, government regulations require use of fall protection equipment, such as railings, many of which are expensive, wasteful, and/or time consuming to use. Accordingly, the present inventor devised some alternatives. One exemplary system incorporates a dual post base plate configured for attachment to a concrete floor via a single concrete anchor bolt, instead of the multiple bolts used conventionally, thereby reducing assembly time and cost. Another embodiment includes a rolling cart assembly which stores the rails in a side-by-side vertical arrangement and the base plates in an interleaved sequence, promoting easy access during installation and inventory control during disassembly and storage. Additionally, some embodiments include four stacking posts that extend upward from the cart, enabling multiple carts to be stacked vertical on atop the other to save space on construction sites.
