Abstract:
An elongate sleeve for protecting elongate members and method of construction thereof has a textile sleeve with a wall having an inner surface providing a cavity extending along a longitudinal axis of the sleeve for receiving the elongate members. A resilient support member is arranged in communication with the wall. The support member has an arcuate shape in lateral cross-section with an outer convex surface facing outwardly from the axis for flush engagement with the inner surface of the wall and an inner concave surface facing inwardly toward the axis. The support member extends less than completely about a circumference of the inner surface.
Abstract:
Eine Hebegurtschlinge zum Heben von Lasten besteht aus einem schlauchartigen Gebilde (20), das mindestens zwei Kammern (2, 2') aufweist and so einen in der Breite zusammenhängenden Kammernschlauch (1) als Einheit bildet. In den mindestens zwei Kammern (2, 2') befinden sich lose eingelegte Einlagen (4), die endlos von einem einen Ende (5) des Kammernschlauches (1) zu dessen anderem Ende (5') verlaufen. Die Einlagen (4) überlappen die Enden (5, 5') des Kammernschlauches (1), sodass dort Schlaufen (3, 3') gebildet werden, wobei die Einlagen (4) im Schlaufenbereich durch einen Schlaufenschutz abgedeckt vorliegen. Ein den Kammernschlauch (1) umgebender and durch verschiedene Webarten gebildeter Schutzschlauch erhöht die Abriebfestigkeit, Schnittfestigkeit and Kantenfestigkeit wesentlich. Die Hebegurtschlinge ist für Lasten bis zu 100 t ausgelegt.
Abstract:
A hoisting member for an elevator system includes a core having strength components embedded in a matrix material. A coating can surround the core to protect the core and control the coefficient of friction of the outer surface based on a range of desired friction properties to prevent or inhibit slippage of the hoisting member when used in a traction elevator system. The strength components may be made from carbon nanotube material with the matrix material made from a polymer material. The hoisting member may also include other conductive material or fiber optic material. The hoisting member may also serve as the trailing cable in an elevator system. In doing so the hosting member transmits power and data between the elevator car and the elevator controller thereby eliminating the need for a traditional trailing cable.
Abstract:
There is provided a high-tensile synthetic fiber rope having a low percentage elongation, the rope dramatically improving the strength utilization rate of the tensile strength of the synthetic fibers, and ensuring the percentage elongation approximately the same as the percentage elongation of the synthetic fibers used in the rope. The synthetic fiber rope includes a plurality of strands twisted or braided together, each of the strands including: a tubular woven fabric woven with warp and weft yarns made of synthetic fibers; and a core material disposed in the tubular woven fabric, the core material being constituted by a plurality of parallel-bundled yarns made of the synthetic fibers in the tubular woven fabric.
Abstract:
A product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibers having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N. The tensile strength is obtained by adjusting the drawing ratio or the UHMWPE filaments/fibers accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath/jacket comprising said first yarn.
Abstract:
An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.
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:
Ein Verfahren zur Herstellung einer Endlos-Rundschlinge, insbesondere nach DIN 61360 zum Anschlagen und Heben von Lasten ausgebildete Rundschlinge, mit einem aus einem seilartigen Bündel von Schnüren bestehend endlosen Strang, der mit einem Überzugsschlauch aus Kunststoffaser-Textilgewebe überzogen ist, dadurch gekennzeichnet, daß der Strang (1) vor dem Überziehen mit dem Textilgewebeschlauch (7) zunächst mit einem für flüssige Medien impermeablen Schlauch (10) aus Kunststoffolie überzogen und erst dann über diesen der Textilgewebe-Schlauch (7) darübergezogen und dieser mit einem Imprägnierungsfluid (12) getränkt wird.
Abstract:
A burst protection sleeve (100), which may be used to protect against bursting from hydraulic or other pressurized hoses and tubes, is disclosed. The burst protection sleeve (100) comprises an inner sleeve (102), and an outer sleeve (104). The inner sleeve (102) and the outer sleeve (104) are joined and the inner sleeve (102) is disposed within the outer sleeve (104). A method of installing such sleeves and a burst protection system are also disclosed.
