Abstract:
A belt for an elevator system includes a plurality of tension members arranged along a belt width, a jacket material at least partially encapsulating the plurality of tension members defining a traction surface, a back surface opposite the traction surface together with the traction surface defining a belt thickness, and two end surfaces extending between the traction surface and the back surface defining the belt width. A metallic coating layer applied from a liquid solution is positioned over at least one end surface of the two end surfaces.
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 composite cable or rope is described. The cable or rope has an inner metallic rope or core, consisting of a plurality of metal strands, and a plurality of covering layers formed around the inner metallic core. An innovative anchoring and safety system is also described. The system has one or more anchorages, fixed to the roof, in each of which the rope is stably locked by screwing, so as not to create instability problems for people attached to the rope.
Abstract:
The present disclosure comprises providing a cable core encased in a polymeric layer, cabling a first armor wire layer about the cable core, cabling a second armor wire layer about the first armor wire layer to form the cable, each of the armor wire layers comprising a plurality of strength members, at least one of the armor wire layers comprising a plurality of strength members having a polymeric layer bonded thereto.
Abstract:
The abrasion resistance of organic fiber based ropes and cords is increased by a outer woven cover of tapes of high molecular weight and more preferably ultrahigh molecular weight polyethylene.
Abstract:
An elevator rope of the present invention includes: a rope main body; and a covering resin layer that covers the periphery of the rope main body, the covering resin layer obtained by cross-linking a molded product of a composition comprising a thermoplastic polyurethane elastomer and a vinyl compound having two or more vinyl groups per molecule or a molded product of a thermoplastic polyurethane elastomer formed by using a polyol having a vinyl group for each molecule. In order to further stabilize the friction coefficient, inorganic fillers such as talc, a glass fiber and titanium oxide may be further mixed in the composition. The elevator rope of the present invention has a stable friction coefficient that does not depend on temperature or sliding velocity.

Abstract:
An elevator rope of the present invention includes: a rope main body; and a covering resin layer that covers the periphery of the rope main body and comprises a molded product of a composition for forming the covering resin layer, wherein the composition is produced by mixing a thermoplastic polyurethane elastomer, a thermoplastic resin other than the thermoplastic polyurethane elastomer and an isocyanate compound having two or more isocyanate groups per molecule. Preferably, a rope main body impregnated with an impregnating solution comprising a hydroxy compound having two or more hydroxy groups per molecule and an isocyanate compound having two or more isocyanate groups per molecule and having a lower viscosity than a melt viscosity of the composition for forming the covering resin layer is used as the rope main body. The elevator rope of the present invention has a stable friction coefficient that does not depend on temperature or sliding velocity.
Abstract:
A rope with a core and a casing surrounding the core. The core is composed of a multitude of synthetic fibers and the casing is composed of a multitude of synthetic fibers that are interlaced with one another. The synthetic fibers that form the casing are composed of polytetrafluoroethylene and form a lightproof and fluid-repellent envelope for the core.
