Abstract:
A belt for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members spaced from each other along a width of the belt and extending longitudinally along a length of the belt. A jacket at least partially envelopes the plurality of tension members and forms at least one outer belt surface along a width of the belt. A groove is located in the at least one outer belt surface extending longitudinally along the length of the belt.
Abstract:
The invention is related to an elevator comprising an elevator car (1) and a suspension roping (R) suspending the elevator car (1), the suspension roping (R) comprising at least one suspension rope (2, 2', 2") connected to the elevator car (1), wherein each of said at least one rope (2, 2', 2") comprises one or more load bearing members (3, 3', 3") embedded in an elastomeric coating (4) forming the outer surface of the rope (2, 2', 2"), and a rotatable traction member (6) engaging the outer surface of said at least one rope (2,2',2").The elevator further comprises means (M, 10) for rotating the rotatable traction member (6). The elastomeric coating (4) is made of microcellular elastomer whereby the rope (2, 2', 2") can receive excessive substance, such as water, and transport it away from the contact between the rope (2, 2', 2") and the rotatable traction member (6).
Abstract:
A wire rope (20) comprises a central core (27), a plurality of outer elongated elements (26) surrounding said central core (27), a polyamide or a polyether block amide (PEBA) coating (22) applied on said central core and said outer elongated elements, and a thermoplastic polyurethane (TPU) coating (24) covering on said polyamide or said PEBA coating (22). The method of manufacturing such a wire rope (20) is also disclosed.
Abstract:
A method for manufacturing a flexible composite belt or cable. In the meth- od, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic pro- files are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
Abstract:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet / greasy conditions.
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.
