longitudinal deck braces 30 and are clamped to substructures 20 at the inverted apexes 36 of the triangular side plates by means of clamps 76 comprising a stamped indentation 77 having a cooperatingly indented closure plate 79 clamped thereto by conventional fasteners to hold swage 81 on cable 24 in one embodiment an esco swage no 402321 has been satisfactorily used on cables 24 in one form of the invention bolt fasteners 78 ae swaged on the opposite ends of cable 24 to interconnect with compatible fittings such as double ended nut 80 whereby the cables 24 mounted on adjacent bridge sections 12 are interconnected it is also contemplated that a single cable might be interconnected between the ends of the staging platform rather than the interconnected cable sections means being provided to lengthen or shorten the cable in response to the addition or removal of bridge sections the interconnected cables 24 are stretched taut to prevent the interconnected bridge sections from sagging and if desired the cables may be tightened to prestress the bridge sections such that the platform bows slightly upwardly referring also to fig7 it will be seen that the swaged on bolts on the outer end of the cables clamped to the end most bridge sections of a staging platform are interconnected with a curved fitting 82 having a transverse hole 84 in its top portion through which it is pinned by means of nut and bolt connection 86 to end fitting 90 which fitting connects the staging platform to the staging 14 at substantially deck level bolt 86 also extends.
