A system for providing re-usable safety support fences and fall restraints for the construction industry. The system comprises a plurality of disposable bases which are welded to I-beams or otherwise permanently attached to a floor or roof, and a plurality of removable support posts that screw into the disposable bases. The support posts form the posts of a safety fence through which steel cables are threaded to form a fence. Also, a fall arrestor, comprising an eye hook onto which a construction or maintenance worker on the perimeter of a building may attach, can be screwed into the permanently mounted disposable base. Additional embodiments for use with concrete construction instead of steel I-beams are disclosed.

A cargo transportation system comprising secure (fully closeable and lockable), sealable, stackable, trackable, universal, auto-latching “pallet boxes” that may be used in two main ways: 1) secured to the undercarriage transverse I-beams of over-the-road semi-trailers by means of loading alignment and hanger assemblies that provide positive locking-in-place; and 2) stackable, up to three or more high, inside the trailer bodies. The inventive pallet boxes are designed to be secured by auto-latching hanger assemblies that are retrofittable on individual types of semi-trailer undercarriages, both US and metric (European, Central and South American, and Asian) standard dimensions. The pallet boxes include vertical sidewall load-bearing channel members permitting stacking fully-loaded pallet boxes three or more high. The pallet boxes may be refrigerated, insulated, or atmospherically controlled, e.g., chargeable with preservative, security or disinfecting gases, during shipping.

An I-beam having a web curved in two dimensions is used to provide an enhanced stiffness to weight ratio for molded plastic hangers. The I-beam includes first and second generally parallel flanges which extend in a longitudinal direction. The flanges are joined by a curved web, which is defined in part by first and second radii of curvature, wherein the radii are nominally orthogonal to each other.

An I-beam anchor for removably securing a fall protection member to an I-beam is disclosed. The I-beam anchor comprises a cross-beam, an anchor ring, and first and second brackets. The first bracket is positioned between a first end and center portion of the cross-beam and the second bracket positioned between a second end and center portion of the cross-beam. Each of the brackets comprises an inwardly directed flange spaced above the body of the brackets. At least the first bracket is a movable bracket and is movable along the cross-beam relative to the second bracket. The moveable bracket comprises a protected “quick release” mechanism that allows for the rapid engagement and disengagement of the anchor to the I-beam, in which the quick release mechanism is configured to minimize the chance of accidental or unintentional release.

A corner connection used to secure I-beams together at corners within the excavation site is provided with a reinforcing assembly that allows for greater loads. Typically, four I-beams are connected together to form a rectangular frame that is suspended within the excavation for bracing the shoring walls thereof; however, any polygonal shape may be used. The corner connection itself comprises mating socket or connecting members that are placed over the ends of I-beams to be fastened together. One of the connecting members includes an outwardly extended tab while the other includes a pair of outwardly extended tabs. The first outwardly extending tab fits between the two extending tabs of the corresponding connecting member. All of the tabs are provided with apertures that are placed in alignment when the connection is made so that a bolt or pin can be passed through the apertures to secure the two connectors together. An additional set of tabs is provided on the connecting members that is also provide with apertures. A reinforcing assembly is provided and includes a reinforcing bar with tabs. A first spacer bar is attached to the reinforcing bar and one connecting member and a second spacer bar is attached to the reinforcing bar and an adjacent connecting member. The spacer bars, the reinforcing bar and the connection members are all connected with tab / pin connections. Advantageously the reinforcing assembly can use the existing second set of tabs located on the prior art connectors. Such an arrangement provides much greater support for the sidewalls of the excavation site.
