Abstract:
An assembly and method for using a flexible tensile member as part of the rigging for a dragline bucket. The tensile member includes a stranded core surrounded by a separate armor layer. The armor layer assumes the form of a hollow cylinder having a substantial wall thickness. A significant gap is provided between the outward-facing surface of the stranded core and the inward-facing surface of the armor layer. This gap minimizes wear between the two elements during the normal bending and flexing of the tensile member. A first anchor is attached to a first end of the stranded core and a second anchor is attached to a second end of the stranded core. These anchors serve to transmit tension carried by the stranded core. A first end of the armor layer is also attached to the first anchor and a second end of the armor layer is attached to the second anchor.
Abstract:
A rope system comprising: a cover (102) having at least one channel and two terminal ends; and a bundle of fibers (104) that form a continuous loop, wherein the bundle of fibers is at least partially disposed within the cover (102) and wherein a portion of the bundle of fibers (104) extends beyond the two terminal ends of the cover and are exposed as loops (105). Moreover, a linked rope system (1800) of fibrous loops (1804), each loop being encased in a cover (1802) and a corresponding method of manufacturing said linked rope system (1800) is disclosed.
Abstract:
A rope (10) comprising a core (12) for providing strength to said rope (10), wherein at least a metal or composite woven or warp knitted fabric (16) comprising multiple substantially parallel elongated metal elements (22, 24) is provided around said core (12) for protecting said core (12) from impact and cutting, and wherein said multiple substantially parallel elongated elements (22, 24) are in the warp direction and held by yarns (23).
Abstract:
A protective cover formed substantially of ultra high molecular weight polyethylene yarns and having first and second opposing edges connected by a high shear strength hook and loop fastener system. The high shear strength hook and loop fastener system includes areas of a plurality of high shear strength hooks along opposing edges of the cover and an intermediate disposable strip having a plurality of loops on both sides of the strip configured to be received between the areas having the plurality of hooks. The cover wraps around the sling so that a portion of the first edge and second edge overlap with the intermediate disposable strip to form the releasable connection. When the edges are released, the intermediate strip may be replaced, when worn, by a new intermediate strip with the remainder of the cover and fastener system being reusable.
Abstract:
A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yams having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yams are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.
Abstract:
A belt used as a rope which as a strength higher than that of a rope of the same mass and a substantially circular cross section, and which is provided at both sides thereof with belt portions. This belt consists of a narrow woven material (10) composed of warp and weft yarn (6, 7) of synthetic fiber filaments, and has a belt body (2) extending in the lengthwise direction of the belt, a belt portion (4), and a joint portion (3) for connecting the belt body (2) and belt portion (4) together. The belt body (2) is formed by weaving core strings (5) into a hollow weave texture, and the warp yarn density factor of a hollow weave member (22) is set to not more than 0.700. The belt portion (4) has a woven structure in which the warp yarn (6) in the hollow weave member of the belt body (2) and a part or the whole of the core strings (5) in the belt body (2) are interlaced with the weft yarn. The belt portion has a width W not less than 2.0 times as large as that W &cir& _ of the belt body (2). The joint portion (3) is formed so that it transmutes to a woven structure of the belt body (2) or that of the belt portion (4) in a plurality of steps with its weaving width gradually decreasing or increasing.
