Benefits of technology
[0009] Thus, the present invention comprises a hanging device that includes two ends that are coupled together. The ends are electrically isolated from one another to create a hanger that can couple a plank to an anchorage without electrically coupling the plank and anchorage such that they may be maintained at electrical differences. That is to say the anchorage point and the MHS system may be electrically isolated from one another. Thus the hanging device acts as an insulator between the structure and suspension cable to prevent cable embrittlement caused by stray currents passing through the rope wire.
[0010] The size and shape of the hanging device lends itself to being readily used by rope walkers during the installation process of the MHS system. A plurality of hanging devices may be clipped onto a belt or rope and easily carried by a rope walker. Since the first and second ends are substantially similar in shape, the rope walker can readily deploy the hanging devices without concern for a proper orientation of the devices. When the rope walker reaches a desired location, a hanger may be readily deployed and secured at one end to an anchorage and at a second end to a rope wire that is coupled to a plank.
[0011] It is an object of the invention to provide a suspension cable assembly that comprises a hanger that electrically isolates a MHS system from a support structure. The hanger provides an electrical insulation between the hull of the vessel or structure upon which work is being performed and the MHS system to prevent electrical currents from passing through suspension cables.
[0012] It is a further object of the invention to provide a hanger that can be easily deployed and used to support a MHS system. In one instance, the hanger supports a load of over four thousand pounds.
[0014] It is a further object of the invention to provide a hanger that is rugged and remains in tact and does not severely degrade during sandblasting and other necessary marine construction operations.
Problems solved by technology
Failure of a MHS system is a major concern to ship repair workers.
Should the MHS system fail, the workers may fall great distances resulting in injury or death.
Previously, MHS systems have failed when the structural integrity of the wire ropes were compromised.
The diameter of the rope was unable to adequately pass the stray current to ground and the structural integrity was compromised causing the rope to be unable to support the load applied between the planking and the anchorage.
A failure of the MHS system occurred resulting in injury to the workers.

Embodiment Construction
[0022]FIG. 1 depicts a MHS system for use with the present invention. The MHS system 101 includes planks 103 upon which workers walk. The planks 103 are supported by pairs of suspension cables 102 that attach to anchorage points (not shown). The hanger 1 attaches to an end of the cable opposite the plank 103 via a screw pin shackle or other such fastening device. A second end of the hanger 1 attaches to an anchor point via a second fastening device. Ladders 104 are provided between the planks 103 for traversing between the different levels of the MHS system 101.
[0023]FIG. 2 shows one embodiment of the invention. It is readily apparent to one of ordinary skill in the art that various other elements may be substituted for those mentioned to achieve the same or similar results. The discussed embodiment of the invention merely discloses the best mode for carrying out the invention.
[0024] In FIG. 2, the hanger 1 comprises a first eyebolt 3A defining a through hole 7A and having a threa...

A hanging device for anchoring a marine hanging staging system includes a first end for receiving an anchor and defining an opening. The first end includes a threaded end. The threaded end attaches the first end to a first nut that includes a threaded opening for receiving the threaded end of the first end. A second opening in the first nut is included for receiving a coupling means such as a strap to couple the nut to a second nut. An insulated block of material is disposed between the first and second nuts. A second end is shaped similar to the first end and includes an opening for receiving a shackle or other such device for coupling the device to a wire rope that supports a plank that forms the marine hanging staging system.
Description
[0001] There are no related patent applications. [0002] The subject matter of the present invention did not receive federal government research and development funding. BACKGROUND OF THE INVENTION [0003] The present invention generally relates to a device for suspending scaffolding comprising planking that supports workers, equipment and / or materials. More specifically, the invention relates to a suspended scaffolding system and device that comprises a first end for accepting an anchorage and a second end coupled to the first end and electrically insolated therefrom for attaching to an end of a cable or rope wire to support a planking therefrom. The present invention is useful in providing scaffolding that may be electrically isolated from a hull of a ship or other such structure to aid in marine construction, repairs and the like of the ship or structure. [0004] Marine hanging staging (MHS) is a type of a tier, level or temporary elevated platform that supports workers, their tools...
