  • Patent number: 11988644
    Abstract: An in-situ bollard tester. The in-situ bollard tester may comprise: a frame, cable, and tensioner. The frame may mount onto a pier and around a bollard to provide structural support for the cable and tensioner. The frame may comprise a pair of base assemblies and a spreader bar. Each of the base assemblies may comprise a support frame and a cantilever arm, and the spreader bar may be coupled to the pair of base assemblies. A pair of jacks are coupled near proximal corners of the base assemblies. The tensioner may comprise a pair of hydraulic arms having first ends coupled near a proximal end of the base assemblies and a linear crossmember coupled to the second ends of the hydraulic arms. 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.

  • 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.
