A pipe-support system including a pipe-support frame structure having plural, substantially horizontal, pipe-support levels supported by columns including a distribution of side columns uniformly spaced along at least one side of the frame structure, and featuring selectively graduated, support-level-indifferent, lateral-connectivity access for quickly available, removeable, outrigger gravity attachment to the frame's side columns, through gravity catch and hook structures, of modular, outrigger, lateral, worker-platform scaffolding either as individual scaffolding units, or as assemblies of plural, individual units, all such units deriving vertical support through outrigger connections made to the frame structure.

A collapsible and portable road sign platform, comprising: a) a square or rectangular platform base portion; b) a square or rectangular platform frame portion comprising a plurality of platform frame members; c) a left platform bracket portion and a right platform bracket portion; and d) a safety railing portion comprising a plurality of safety railing frame members, wherein the left platform bracket portion and/or the right platform bracket portion are/is adjustable, and wherein the road sign platform is capable of being affixed off the ground to a pair of wood posts.

A vertical raising safety rail. The safety rail includes lower linkage arm assemblies that are connected to a base and to a center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes upper linkage arm assemblies that are connected to the center rail assembly and to a top rail. The upper linkage arm assemblies are connected to corresponding lower linkage assemblies and are configured to move the top rail relative to the center rail assembly. When the top rail is raised, one or more safety curtains are unfurled from a take-up roller inside the top rail to provide a safety curtain in the vertical plane of the safety rail.

A scaffold ledger providing a raised support surface of the elongate structural member with the opposed ledger heads being downwardly and outwardly offset. Each ledger head includes cover flaps that extend the raised support surface above the ledger heads in a cover position. The scaffold ledger cooperates with scaffold posts and scaffold planks to allow for a continuous work platform above an intermediate scaffold support post and/or across supporting ledgers.

The invention includes a work platform and support system that includes a hub and joist configuration, wherein the hubs and joists are capable of articulation, or pivoting. One method of installation allows for sections of new work platform system to be extended from an existing suspended work platform system. The system is also capable of supporting, without failure, its own weight and at least four times the maximum intended load applied to it.

A height adjustable platform assembly securable to a building including a pair of anchors each removably mountable to the building through an opening thereof at a respective one of the opening lateral edges; a pair of supports each removably mounted to a respective one of the anchors; and a platform positionable so as to extend between the supports and be supported thereby. With the height adjustable platform assembly operatively secured to the building with the anchors mounted through the building opening, the supports each protrude outwardly from the building and support the platform outside of the building adjacent to the building outside surface. Each support is mountable to the respective one of the anchors at at least two vertically spaced apart locations therealong to allow adjustment of a vertical position of the platform relative to the building.

A vertical raising safety rail having a moveable top rail, a base, a movable center rail assembly positioned above the base and below the top rail, a drive shaft, and a motor that provides rotational power to the drive shaft. The safety rail further includes a pair of spaced apart lower linkage arm assemblies that is operatively connected to the base and to the center rail assembly and configured to raise or lower the center rail assembly relative to the base when a rotational force is applied to the drive shaft. The safety rail also includes a pair of spaced apart upper linkage arm assemblies that is operably connected to the center rail assembly and to the top rail. The upper linkage arm assemblies are operably connected to corresponding lower linkage assemblies and are configured to move the upper rail relative to the center rail assembly. When the rotational force is reversed, the safety rail collapses into a compact footprint.
