  • Patent number: 5749434
    Abstract: Apparatus for minimizing the risk of falls from the edge of a roof deck during installation of deck panels (14) on beam members (12) of a building frame, includes a platform (26). The platform includes frame members (32) that are rollably movable on the beam members. The platform is movable using a plurality of handles (38) which also operate to hold a safety line (62). A trailing edge (28) of the platform is maintained in closely adjacent relation to the front edge of a last placed deck panel. This minimizes the unsupported area between the last placed panel and the platform and avoids the risk of falls during installation of the roof deck.
