  • Patent number: 11971391
    Abstract: An in-situ bollard tester. The in-situ bollard tester may comprise: a frame, cable, and tensioner. The frame is preferably adapted to mount onto a pier or wharf and around a bollard to provide structural support for the cable and tensioner. The frame may comprise a rectangular frame, pair of hanging columns, pair of jacks and pair of legs. The pair of jacks are coupled near proximal corners of the rectangular frame and are vertically disposed. The hanging columns are coupled near distal corners of the rectangular frame. The pair of legs are coupled at the lower ends of the hanging columns and are disposed in a horizontal manner. The tensioner may be coupled above the rectangular frame. The cable may fasten to the bollard, and the tensioner may apply tension to the cable at various load angles in order to test the integrity of the bollard.

The frame is preferably adapted to mount onto a pier or wharf and around a bollard to provide structural support for the cable and tensioner. The frame may comprise a rectangular frame, pair of hanging columns, and first and second pair of legs. The first pair of legs are coupled near proximal corners of the rectangular frame and are vertically disposed. The hanging columns are coupled near distal corners of the rectangular frame. The second pair of legs are coupled at the lower ends of the hanging columns and are disposed in a horizontal manner. The tensioner may be coupled above the rectangular frame.

  • Patent number: 7453177
    Abstract: The magnetic coupling system of the present invention overcomes drawbacks experienced by the prior art. A coupling system in accordance with one embodiment of the invention comprises a rotor assembly having a first mount portion connectable to a first shaft. A conductor assembly having a second mount portion is connectable to a second shaft. The second mount portion has first and second sections coupleable to each other and being independently positionable adjacent to the magnet holder. A first electro-conductive member is attached to the first section and positioned adjacent to the magnet holder. A second electro-conductive member is attached to the second section and positioned adjacent to the magnet holder. The first and second electro-conductive members are positioned adjacent to each other and spaced apart from the magnet holder by a gap.
