Abstract:
The present invention relates to a photo-luminescent wire rope having an extended luminescent effect, and to a method for manufacturing the same. The photo-luminescent wire rope of the present invention comprises a plurality of outer layer strands which are woven around the outer circumference of a core strand, wherein at least one of said outer layer strands is a photo-luminescent wire rod into which a mixture of a photo-luminescent pigment and a synthetic resin is extrusion-molded. The method for making the photo-luminescent wire rope of the present invention comprises the steps of: mixing a photo-luminescent pigment with a synthetic resin and extrusion-molding the mixture into a photo-luminescent wire rod; preparing a plurality of wires by wire-drawing a steel wire rod; preparing a plurality of strands by weaving said wires; selecting one strand from said plurality of strands as a core strand; and weaving the remainder of said plurality of strands and said photo-luminescent wire rod, which act as outer layer strands, around the outer circumference of the core strand, thereby forming a photo-luminescent wire rope. The photo-luminescent wire rope of the present invention is excellent in maintaining luminance and photoluminescence, thereby facilitating detection of potential dangers at night or in dark places and preventing potential accidents.

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 thin buffer layer (303) is used to coat on the multi-filament (401) wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials.
Abstract:
Die Erfindung betrifft einen Aufzug mit Riemenscheiben (37) und mindestens einem Flachriemen (33) zum Tragen und Bewegen einer Aufzugskabine. Um den Flachriemen (33) auf den Riemenscheiben (37) zu führen, weist dieser mindestens eine Führungsnut (33.4) auf, in welche mindestens eine aus der Scheibenlauffläche (37.1) der Riemenscheibe (37) hervorstehende Führungsrippe (37.2) eingreift.
Abstract:
An elevator rope comprising an elastomer coated, multistrand steel wire cable is claimed. In such a cable strands have a lay-length of at least 6.5 times the diameter of the bare cable diameter D. The cable is further coated with an elastomeric jacket, which adheres to the strands with a pull-out force not less than 15xD+15 newton per mm. The advantages of such an elevator rope are amongst others its limited elongation, its reduced diameter and its improved fatigue life.
Abstract:
An elevator load bearing assembly (40) includes a plurality of synthetic or polymer cords (42) within a urethane jacket (44). The cords are prestretched and the jacket prevents the stretched cords from relaxing. The inventive arrangement provides a load bearing assembly (40) that has little or no elastic or construction stretch.
Abstract:
An elevator in which the sheave diameter is reduced and the attendant lowering of the rope life and strength is suppressed to secure safety and reliability. To this end, a rope is used in which a plurality of element wires constituting the wire rope are each covered with resin material and the whole wire rope is covered with resin material, thereby reducing the wear due to slippage between the element wires and the wear due to contact with the sheave, which wear occurs when the rope is entrained around the sheave. When the elevator sheave diameter is reduced, a worried lowering of the rope life can be suppressed or the rope life can be improved. Thus, it is possible to achieve reduction of size and weight of equipment including motors and hoists, installation space saving for elevators, improved safety and reliability of the system by virtue of the increased rope life.
