Abstract: A round sling system comprises a bearing structure, a cover, and at least one organizer secured to the cover. The bearing structure is arranged to define a plurality of loop portions and to define at least one bearing structure end portion. The cover defines a cover chamber. The at least one organizer is configured to engage the bearing structure such that the at least one organizer maintains a position of the bearing structure relative to the cover and the at least one organizer maintains a spatial relationship of the loop portions at least within the at least one bearing structure end portion.

Abstract: A method for non-destructively estimating a current physical condition of a cordage product in-service is described. The method involves obtaining sensor data associated with the cordage product while in-service handling a load. The sensor data includes any combination of cordage product elongation data, applied load data, and diametric data. The method further includes determining an axial stiffness value associated with the cordage product based on the sensor data and estimating a health state of the cordage product based on the determined axial stiffness value. The estimated health state is indicative of the current physical condition of the cordage product.

Abstract: A rope system adapted to be connected between first and second structures comprises a rope recoil system comprising first and second rope recoil assemblies. The first rope recoil assembly defines a first length and a first predetermined rope recoil maximum limit at which the first rope recoil assembly fails when under tension. The second rope recoil assembly defines a second length, where the second length is longer than the first length. The rope recoil assembly is arranged between the first and second structures such that the rope recoil system is in a first configuration. When at least one of the first and second structures moves away from another of the first and second structures, the first rope recoil assembly fails and the rope recoil system reconfigures into a second configuration.

Abstract: A round sling includes a line arranged to define a plurality of loops and a plurality of organizers. The organizers engage the line such that each of the plurality of loops defines a first segment, a second segment, a third segment, and a fourth segment. The first and third segments extend between the first and second ends of the round sling. The second and fourth segments define the first and second ends of the round sling. At least one first segment of at least one of the loops crosses over at least one first segment of at least one other loop. The second and fourth segments of the loops defining the first and second ends of the round sling are maintained in a fixed, substantially parallel relationship.

Abstract: A rope assembly that is adapted to extend between first and second attachment points comprises a line arranged to define a plurality of loops and at least one pair of organizers. The at least one pair of organizers is configured to engage the line such that line segments of the line between the at least one pair of organizers are maintained in a desired relationship with each other and such that the desired relationship facilitates transfer of loads through the rope assembly between the first and second attachment points.

Abstract: A dragline excavator system has a support assembly, a hoist coupler assembly suspended from the support assembly, a bucket assembly suspended from the hoist coupler assembly, a sheave assembly supported by the hoist coupler assembly, a drag coupler assembly, and at least one dump rope operatively connected to the drag coupler assembly and the bucket assembly. The at least one dump rope extends through the sheave assembly. The at least one dump rope is formed of at least one fiber made from at least one of high modulus polyethylene (HMPE), poly-p-phenylenebenzobisoxazole (PBO), liquid crystal polymer (LCP), aromatic polyamide (Aramid), polyester, nylon, polyolefin, polypropylene (PP), carbon, and glass.
