摘要:
The invention relates to a heavy-duty roundsling, which comprises an endless load-bearing core containing multiple turns of a strand material comprising high-performance fibres, and a protective cover made from interlaced strands comprising high-performance fibres, and wherein the mass ratio of high-performance fibres in the core to high-performance fibres in the cover is from 0.15 to 2.0. Said roundsling shows an advantageous combination of properties, like high strength, low weight, and high durability; enabling a higher number of lifting operations than known metal or synthetic slings, especially of heavy goods with e.g. sharp edges.

Dieses Trag- und Treibmittel (11) hat die Geometrie eines Riemens bestehend aus einem Riemenkörper (12) bzw. Mantel (12), der die Zugträger (1) umschliesst. Jeder Zugträger (1) aufweist mehrere Litzen (7,8,9,10), wobei jede Litze (7,8,9,10) aus mehreren verseilten Garnen gebilded ist. Die Lauffläche (16) des Riemens kann flach und parallel zum Riemenrücken (13) sein oder trapezförmige oder halbkreisrunde Rippen (14) und Rillen (15) aufweisen, wobei die Kontur einer Treibscheibe bzw. einer Umlenkscheibe etwa komplementär zur Lauffläche (16) des Riemens ist. Je Rippe (14) sind ein oder mehrere Zugträger (1) vorgesehen, wobei die Zugträger (1) abwechselnd in Z- und S-Richtung geschlagen bzw. verseilt sind.

According to the invention, a high-security cable may be produced which can support extremely high loads within a relatively short period of time, by means of a cable made from a mixture of various synthetic yarns or synthetic yarns and metal wires. Said synthetic yarns and metal wires shall be present in the cable in three different production forms, namely in one form as twisted or untwisted yarns or wires, in a second form as twists and in a third form as cords. The twists and the cords are produced from twisted or untwisted yarns or wires. According to the invention, a twist is made from two yarns and a cord from three yarns. Said high-security cables are advantageously applied to automobile racing for the attachment of a wheel to the chassis of the racing car and for the production of security catch cables of application for piste security as temporary avalanche catch nets or temporary falling stone protection nets.

A static rope having an outer braided mantle (4) and an inner core (1) formed by three or more strands (2) which each comprise a set of fibre bundles (3), where the core (1) and the mantle (4) are each made from synthetic fibres with an elasticity of less than 20%, where the rope is provided with a loop (6) fashioned at one end of the rope which is formed by the rope being bent at the said end and forming, to create the said loop (6), two portions starting from the loop (6), a long portion (7) and a short portion (8), which portions are positioned next to and in contact with one another and are joined together by a seam (9) which runs along the portions and engages in both portions, and also a mast or boom construction which comprises such a rope.

A synthetic rope (1) for an elevator having improved resistance to compression and abrasion is provided and comprises a plurality of strands (7) forming layers of the rope, each strand formed from a plurality of pre-twisted strands (19) from high modulus synthetic filaments (21). One or more of the strands or layers of strands may be impregnated with a lubricant, such as polytetrafluoroethylene, to reduce the abrasion among the strands and substrands, and increase the service life of the rope. The exterior of the rope may be covered by a jacket (35) that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.
摘要:
Seil oder Seilelement (2) mit mindestens einem aus textilem Fasermaterial, insbesondere Kunststoff-Fäden gebildeten Strang (3) und mit einer über die Außenseite dieses Stranges verlaufenden Bewehrung (4). Diese Bewehrung (4) ist mit Bewehrungselementen in Form von Kunststoff-Monofilamenten (5a, 5b) und/oder Kunststoff-Fäden, Kunststoff-Garnen (5c, 5d) oder Kunststoff-Zwirnen gebildet. Diese Bewehrungselemente haben gegenüber einer glatten kreiszylindrischen Metallfläche einen größeren Haftreibungswert als Polyamid-Monofilamente mit von Fremdstoffen freier Oberfläche und eine Abriebbeständigkeit, die mindestens 80 % im Seilverband vorliegender Abriebbeständigkeit von Polyacrylgarn beträgt. Der Strang (3) bzw. die Stränge des Seilelementes (2) sind vorzugsweise aus Kunststoff-Multifilamenten aus Polyamid und/oder Polyester gebildet und es ist günstig, wenn der Strang (3) bzw. die Stränge (3) mit den Bewehrungselementen der Bewehrung (4) umflochten oder umstrickt sind.
摘要:
The invention relates to rope-like structures, in particular, kernmantel ropes, cords and cables in which the individual fibres, threads or thread bundles (5, 5', 6, 6') are connected to each other such that the above are non-slip relative to each other. Such rope-like bodies have an improved resistance to extension and an improved knot stability. Kernmantel ropes (10) have a proportion of the core fibres (5') in the sheath region (2) and connected therein to the sheath fibres (6), whilst a proportion of the sheath fibres (6') lie in the core region (1) and are connected therein to the core fibres (5), such that the at least one sheath (4) is fixed to the at least one core (1), such that the above are non-slip relative to each other. Cords and cables with similar properties are disclosed. Such ropes are applicable in the field of work security, in water, sailing and mountain sports and for the fire service, army, police and rescue units as well as in Jacquard machines.
摘要:
Endless rope (10) containing primary strands (12), the primary strands (12) containing laid-up secondary strands (14), the laid-up secondary strands (14) containing rope yarns (16), wherein the primary strands (12) have been laid up from 3,4 or 6 secondary strands (14), wherein the rope (10) contains a splice in at least every primary strand (12) and wherein the rope (10) preferably has been laid up from 3, 4 or (1+6) primary strands (12) or, alternatively, has been braided from 8 or 12 primary strands (12).
