A vacuum anchor for securing a fall protection system to a surface has a gas inlet to receive pressurized gas from a gas container and generates a vacuum to secure the anchor to a surface. An attachment enables a fall protection system to be connected to the anchor, the attachment being rotatably mounted to the anchor. A container mounting device is provided for mounting the gas container to the anchor in connection with the gas inlet, the container mounting means being rotatable with the rotatable. Alternatively or additionally, the gas inlet is coaxial with the axis of rotation of the attachment means.

Adjustable debris collection apparatus for maritime vessels and associated methods

A debris collection apparatus for a maritime vessel includes a shroud and a plurality of support structures. Each of the plurality support structures include a boot defining a cavity and configured to be secured to the vessel, a foot sized to fit within the cavity and including a frame having a rotatably mounted first universal swivel, a staff cap including a staff cap terminal having a rotatably mounted second universal swivel rotatably, a stabilizer base configured to be secured to the vessel and including a body having a rotatably mounted third universal swivel, an elevational staff section removably connected to the first universal swivel and staff cap terminal, and a horizontal staff section removably connected to the second and third universal swivels. The foot is inserted into the boot to secure the support structures in a rigid position, and the shroud is connected to both staff caps and the vessel.

09550079 · 2017-01-24 ·

The multilevel railcar safety catch system of the present disclosure comprises at least two multilevel railcars (or at least one multilevel railcar and a vehicle loading ramp), at least two bridge plates, and a safety catch assembly. In the preferred embodiment of the disclosure, two or more multilevel railcars are coupled together by a coupler. Two bridge plates are laid across the gap between corresponding multilevel railcar decks for the purpose of walking or moving vehicles across from one multilevel railcar to another. A safety catch assembly is removably attached underneath the bridge plates via a securement means on the safety catch assembly and barrel rings or bridge plate hinge pins in such a way as to prevent persons or items from falling through the gap between the multilevel railcar decks when loading or unloading vehicles.

Equipotential mat using wire mesh netting

Disclosed is an equipotential (EPZ) matting for creating an equipotential zone at a work site. A wire mesh of the EPZ matting is constructed by first cutting desired lengths of cable and laying the lengths of cable parallel and adjacent to each other. The cables are then connected to one another at regularly spaced intervals along the cables using pressed metal ferrules. The connections are staggered as between adjacent cables to create an evenly spaced, open mesh pattern when the wire mesh is tensioned perpendicularly to the longitudinal axes of the cables when initially laid along side one another. The wire mesh is opened and pulled tight for use as EPZ matting on the work site. After work is completed, the mesh is closed and bundled for transport, storage, and re-use.
