    摘要: The knot protector protects ropes and knots from ledges, rocks, railings, edges, walls, cliffs, and other surfaces that may cause the fibers of the rope to be gradually abraded or destroyed. The knot protector includes a sleeve formed from an upper portion, a lower portion, and a shoulder portion. The upper portion defines a first opening while the lower portion defines a second opening. The diameter of the first opening is smaller or less than that of the second opening. The sleeve is formed from a deformable, continuous web and has exterior and interior layers. The sleeve also contains visual safety indicators along the base of the lower portion to provide visibility. The exterior and interior layers are made from durable material to provide the rope with ample protection from abrasion.

    摘要: Provided is a cable lock including a locking clasp including first and second clasp components having first and second security cable connection arms. The locking clasp includes at least one groove. The at least one groove is configured to receive at least one device cable. The cable lock includes a security cable having a wire rope and a vinyl coating. The wire rope includes a plurality of wire strings arranged in a plurality of clusters. The first and second security cable connection arms of the locking clasp are coupled to a first end of the security cable. First and second stop sleeves are disposed on opposite sides of the first and second security cable connection arms. A device connection means is disposed at a second end of the security cable opposite the first end of the security cable.

    摘要: A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

    摘要: A hoisting member for an elevator system includes a core having strength components embedded in a matrix material. A coating can surround the core to protect the core and control the coefficient of friction of the outer surface based on a range of desired friction properties to prevent or inhibit slippage of the hoisting member when used in a traction elevator system. The strength components may be made from carbon nanotube material with the matrix material made from a polymer material. The hoisting member may also include other conductive material or fiber optic material. The hoisting member may also serve as the trailing cable in an elevator system. In doing so the hosting member transmits power and data between the elevator car and the elevator controller thereby eliminating the need for a traditional trailing cable.
