Abstract:
A safety cable system for use in erecting the steel framework during the construction of bridges and buildings so that the lanyard of a worker's safety harness may be slidably connected thereto comprising:a plurality of removable stanchion assemblies adapted to be mounted on a structural beam prior to its installation in a building frame, said assemblies including:a main stanchion having a fork member thereon with a pair of upstanding fork arms, each fork arm having an opening therethrough to form a pair of axially aligned fork arm openings axially spaced from one another along an axis perpendicular to said structural beam,at least one intermediate stanchion; andan end stanchion;a cable supply reel journaled on said main stanchion for rotation about a reel axis and having a pair of axially spaced circular flanges,a length of cable on said reel;said reel being adapted to wind said cable thereon to retract said cable or to unreel said cable therefrom whereby said cable may be extended and slidably connected to an intermediate stanchion and fixedly connected to said end stanchion; andmeans for selectively locking said reel flanges to said main stanchion when said cable is extended to and connected to said end stanchion, said locking means comprising a plurality of circumferentially spaced openings in each flange to form pairs of aligned flange openings axially spaced from one another and in opposite flanges, said pairs of flange openings adapted to be selectively aligned with said fork arm openings, anda lock pin adapted to be moved axially through said fork arm openings and through a pair of said flange openings to a locking position to lock said reel against rotation in either direction relative to said main stanchion.
