  • Patent number: 12123476
    Abstract: A method for attaching an anchor to an end of a tensile member by inverting the assembly of anchor and tensile member and injecting pressurized potting compound. A length of filaments of the tensile member are placed within a cavity through the anchor. The anchor and filaments are placed in an inverted position, with the distal end of the anchor facing downward and the cable extending upward out of the anchor. If the anchor has an open distal end this is sealed. Liquid potting compound is injected into the anchor cavity and allowed to solidify. During the solidification process, a controlled translation (pulling) of the cable is preferably introduced.

  • Publication number: 20240328113
    Abstract: A method and hardware for damping and controlling unwanted motion in the fixed rigging of large machines. In a first approach large clamp blocks are added to multi-cable rigging systems. These blocks use a first cable to damp the motion of an adjacent cable. The invention also encompasses adding armored sections to synthetic cables to enhance their abrasion resistance and cut resistance.

  • Patent number: 12077909
    Abstract: A method for producing a synthetic tensile member having a precisely known and stable length. The invention also comprises equipment configured to carry out the method. A tensile member is prepared by attaching terminations to an assembly of synthetic filaments. The tensile member is then attached to a loading apparatus that subjects the tensile member to a pre-defined loading process. The tensile member is thereby conditioned to a stable length. The length is then measured and a length adjusting component is incorporated into the tensile member to create a precise and stabilized length that is configured for the tensile member's particular application.

  • Publication number: 20240209918
    Abstract: A compact overall termination for a multi-stranded synthetic filament cable that provides for the inspection of the individual components. Multiple individual cable strands are provided with a strand termination on their free end. These strand terminations are connected to a collector to form an overall cable termination. An advanced collar is provided that reroutes the strands as they leave the collector and controls the transition to the structure found in the free portion of the cable. The advanced collar often shortens the length required for the transition from the collector to the free portion of the cable.

  • Publication number: 20240149327
    Abstract: A method of making a wheel assembly using hybrid spokes that combines a synthetic fiber cable with an outer rod segment connected to a rim and an inner rod segment connected to a hub. An anchor is used to connect each end of the fiber cable to a length of conventional rod, preferably through the use of a swaging operation. Each rod segment includes a standard end feature on its free end—such as a threaded shaft or J-bend. The hybrid assembly can preferably be retrofitted to applications that now use a conventional rod or wire. This allows synthetic fiber cables—with their unique mechanical properties—to be incorporated in existing designs.

  • Patent number: 11946820
    Abstract: A system and method for performing structural health monitoring on a structural element while it remains in service and experiences normal loading. The energy input to the element will be the normal and random energy inputs the element sees in service. The inventive system places an intelligent module at one or more points along the length of the structural element. The inventive system collects mass data from multiple modules on multiple elements. The system then applies machine learning or artificial intelligence techniques to detect changes in the measurements received from one or more modules. This approach reduces or eliminates the need to provide calibrated input energy. The invention preferably provides the ability to determine the condition of one element or sub-element under measurement relative to other elements.

  • Patent number: 11884100
    Abstract: A method and system for creating a hybrid tensile member combining a synthetic fiber cable and a rigid rod. An anchor is attached to one or more ends of the synthetic cable. The anchor is used to connect an end of the fiber cable to a length of conventional rod, preferably through the use of a swaging operation. Each rod segment includes a standard end feature on its free end—such as a threaded shaft or J-bend. The hybrid assembly can preferably be retrofitted to applications that now use a conventional rod.

  • Publication number: 20230258740
    Abstract: A system for monitoring the performance of a multi-stranded tensile member where a portion of the strands are concealed within a termination. The invention provides a monitoring system that allows the user to determine when one or more of the strands has degraded to a point of concern. In some embodiments the monitoring system depends on visual inspection and in other embodiments the monitoring system is automated.

  • Patent number: 11650120
    Abstract: A calibration process for use in calibrating intelligent cable modules. A separate calibration load cell is provided. This device is placed in the load path for the cable on which the intelligent cable module is installed. The calibration load cell then establishes a communication link with the intelligent cable module. An iterative series of loading cycles are started. Tension data as measured by the calibration load cell is used to create a calibration curve. This calibration curve is used to correlate internal measurements made by the intelligent cable module against a desired value—such as cable tension.

  • Patent number: 11608873
    Abstract: A cable termination in which part of the potted region is free to flex somewhat. A portion of the potted region is maintained within an anchor and rigidly held in the conventional fashion. Another portion, however, extends out of the anchor to ease the transition between the unpotted cable filaments and the filaments locked within the anchor.

  • Publication number: 20230047902
    Abstract: A protected synthetic tensile member assembly including one or more fixed terminations used to transmit a tensile load from the tensile member to an external component. The tensile member includes access for inspection of its constituent fibers in at least one selected inspection region. The region is selected on the basis of the area of interest to the tensile member's use—such as the area of greatest stress concentration or the area of greatest abrasion. A removable cover is provided for the inspection region. A user may selectively remove this cover in order to gain access to the inspection region.
