A saw horse may include a center beam, a first leg connected to the center beam, and a second leg connected to the center beam. The first leg may rotate and may traversely extend and retract to move between an open and a stowed position. The second leg may rotate and traversely extend and retract to move between the open and the stowed position. The saw horse may include a flexible axis biasing device to connect to the first leg. The saw horse may include a flexible axis biasing device to connect to the second leg.

An apparatus that provides a platform for selectively deployable worker access with fall protection to at least a portion of the top of a container disposed above the ground. The apparatus includes a gate and a ladder extension that selectively operates in an extended mode and a retracted mode with respect to the gate and with respect to an emergency egress ladder extending beneath the platform.

A foldable quad-chord truss which can be connected end-to-end with like trusses. Each pair of chords are rigidly attached, and connector members intermediate the ends are swivelly attached to the chord pairs to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to connector members of beams which may extend perpendicular to a parallel pair of the trusses and attached thereto. The laid trusses and beams is overlaid with sheets of corrugated sheet metal which overlap each other along their adjacent edges. While standing on a sheet of laid sheet metal adjacent ends of an already laid pair of trusses, another truss can be held adjacent the edge of the sheet metal for attaching an end of the other truss along only one side so that it can then be swung outwardly into a position wherein the other end of the other truss can also be attached to rigidly connect the trusses end-to-end.

The invention includes an access structure integration assembly and an integrated system using the assembly. An access structure integrated assembly includes at least one channeled structure and at least one joist socket slidingly engaged with the channeled structure. The channeled structure is configured to secure to a base structure, such as a suspended work platform system, and the joist socket is configured to secure to a second structure, such as a supported work platform system. An integrated system includes a base structure, a second structure and at least two integration assemblies, each assembly including a channeled structure secured to the base structure and a joist socket secured to the second structure and slidingly engaged with the channeled structure.

A foldable work platform is disclosed. The foldable work platform includes legs on the exterior of the platform for increased stability while allowing the legs to fold coplanar to the platform when the foldable work platform is in its stored configuration. The legs are also configured to fit within the profile of the platform and attached to the platform at a location which allows the legs to fit within the length of the platform. The legs include a support, on which the platform rests when the foldable work platform is in its in-use configuration.
