Abstract:
An elevator rope has a core rope, and twelve outer layer strands that are arranged on an outer peripheral portion of the core rope at intervals from one another. The core rope has a core strand, an inner layer covering member with which an outer periphery of the core strand is covered, six inner layer strands which are arranged on an outer peripheral portion of the inner layer covering member at intervals from one another, and an outer layer covering member with which the core strand, the inner layer covering member and the individual inner layer strands are collectively covered. The core strand, the individual inner layer strands and the individual outer layer strands are respectively composed of a plurality of elemental wires twisted together.
Abstract:
An annular metal cord and an endless metal belt are provided which have superior breaking strength and which are easy to be produced. The annular metal cord includes an annular core portion 3 and an outer layer portion 4. The annular core portion 3 is formed by connecting together both ends of a first strand material 1 which is made up of six twisted first metal filaments 5. The outer layer portion 4 is formed by winding spirally a second strand material 2 which is made up of six twisted second metal filaments 6 around the annular core portion 3. The second strand material 2 is wound at a predetermined winding angle relative to a center axis of the annular core portion 3, and a winding initiating end portion and a winding terminating end portion thereof are connected together. Since it is not that six second strand materials 2 are not wound but that the second strand material 2 is wound six rounds, there only has to be the single second strand material 2, and there is only one connecting portion. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
Abstract:
A novel high tensile strength semi-absorbable composite suture (10) with minimized non-absorbable mass. The suture has a core (60) made from a bioabsorbable polymer (70). The core is covered by a braided sheath (20). The braided sheath is made from a nonabsorbable yarn (30) and a bioabsorbable yarn (35). The bioabsorbable yarn is made from a least one filament of a bioabsorbable polymer. The nonabsorbable yarn is made from at least one filament of ultra high molecular weight polyethylene.
Abstract:
An elevator rope includes: an inner layer rope; an inner layer covering body formed of resin and covering the outer periphery of the inner layer rope; an outer layer which is provided in the outer periphery of the inner layer covering body; and an outer layer covering body formed of a high-friction resin material and covering the outer periphery of the outer layer. The inner layer rope has a plurality of inner layer strands. The outer layer has a plurality of outer layer strands and adhesive layers glued to the outer periphery of the outer layer strands. The inner layer strands have a plurality of exposed portions partially exposed through the outer periphery of the inner layer covering body, with the exposed portions being in direct contact with the outer layer.
Abstract:
In a rope comprising a bundle of wires (21, 31, 32) each of which is adapted to bear a tensile load to be borne by the rope, predetermined one (32) of the wires is configured to be at least partially breakable by applying tension and flexure to the rope, before an at least partial breakage of a rest of the wires (21, 31) other than the predetermined one (32) of the wires by applying the tension and flexure to the rope.
Abstract:
In an elevator, which preferably is an elevator without machine room, a hoisting machine engages via a traction sheave a set of hoisting ropes comprising hoisting ropes of substantially circular cross-section. The ropes have a load-bearing part twisted from steel wires of circular cross-section and/or steel wires of non-circular cross-section. The average of the wire thicknesses of the steel wires of the hoisting ropes is less than about 0.5 mm and the wires have a strength exceeding about 2000 N/mm 2 .
