Abstract:
[Object] To provide a pneumatic tire 22 that allows a low fitting pressure to be achieved without impairing a tightening force. [Solution] The tire 22 includes a pair of beads 30 and a carcass 32 extending on and between both beads 30. Each bead 30 includes a core 48. The core 48 includes: a main body 56 including a cord 60 extending in a circumferential direction; and a stretchable portion 58 formed from a crosslinked rubber. The stretchable portion 58 is located inward of the main body 56 in an axial direction. The stretchable portion 58 has a size with which at least one cross-section of the cord 60 can be included therein in a cross-section of the bead 30. Preferably, in the tire 22, the main body 56 includes a hard unit and a soft unit. The soft unit is located outward of the hard unit in a radial direction. A hard cord of the hard unit stretches more easily than a soft cord of the soft unit.
Abstract:
The invention relates to a hoisting rope (2,2') for a hoisting apparatus, the hoisting rope (2,2') having a longitudinal direction (I), thickness direction (t) and width direction (w), and comprising a group (G) of load bearing members (3) made of composite material comprising reinforcing fibers (F) embedded in polymer matrix (m); and a coating (4) encasing said group (G) of load bearing members (3); wherein said load bearing members (3) extend in an untwisted manner inside the coating (4) parallel with each other as well as with the longitudinal direction (I) of the rope (2,2') throughout the length thereof, said load bearing members (3) being substantially larger in width direction than in thickness direction of the rope (2,2') and stacked against each other in thickness direction (t) of the rope (2,2'). The invention also relates to an elevator comprising said hoisting rope (2,2').
Abstract:
An exemplary method of making a woven fabric (20A, 20B) includes weaving a plurality of load supporting tension members (22A, 22B) and a plurality of cross fibers (24) together into a woven fabric (20A, 20B). Two woven fabrics (20A, 20B) are positioned next to each other. The two woven fabrics (20A, 20B) include a spacing between adjacent tension members (22A, 22B) having a first dimension. At least one tension member (22A) of one woven fabric (20A) is aligned with and between two of the tension members (22B) of the other woven fabric (20B) to thereby decrease the spacing to a second, smaller dimension.
Abstract:
The invention relates to a method of coupling first and second ropes together, such as to form a mooring line. In one embodiment, a method of coupling a first rope (100) having a core (112) comprising a plurality of multi-strand subropes (1 14) to a second rope (200) having a core comprising a plurality of multi-strand subropes is disclosed. The method comprises the step of forming an eye end termination (116) on the first rope (100) by coupling at least one pair of subropes (114) in the first rope core (112) together to thereby form at least part of a first loop (150, 152) of the eye end termination; and coupling at least one further pair of subropes (114) in the first rope core (112) together to thereby form at least part of a further loop (150, 152) of the eye end termination, said further loop being separate from the first loop. The method also comprises forming an eye end termination (216) on the second rope (200) by coupling at least one pair of subropes in the second rope core together to thereby form at least part of a first loop (250, 252) of the eye end termination; and coupling at least one further pair of subropes in the second rope core together to thereby form at least part of a further loop (250, 252) of the eye end termination, said further loop being separate from the first loop. The loops of the eye end termination of the first rope and the loops of the eye end termination of the second rope are then mounted on a connecting spool (58) to couple the ropes together.
Abstract:
The invention relates to a cable comprising filaments (10) containing carbon, surrounded by a sizing material (12). Said filaments (10) surrounded by the sizing material (12) are covered by a matrix (14) which is composed of a material containing at least one elastomer and/or at least one thermoplastic elastomer. Said cable can be used, in particular for pulling a load, for example in a goods lift.
Abstract:
Umbilical device, wherein said device has a longitudinal axis (x), and comprises:
at least one elongated electrical cable (4) and/or tube (5) element an elongated load bearing component (1) along said longitudinal axis (x) and having an external surface (2) including at least one groove (3) disposed along said longitudinal axis (x) and parallel thereof, said component including a central core (1) encompassed by a plastic or elastic layer (2), which is provided with said at least one groove (3), characterizing in that said groove (3) is designed for holding said cable (4) and/or tube (5) element within it, while allowing said cable (4) and/or tube (5) element to move substantially radially in said groove (3) when said umbilical is bent and that said layer (2) consists of several plastic or elastic elements (2a).
Abstract:
A new form of construction for synthetic cables used for the anchoring of floating platforms in offshore oil production is described. A desirable requisite for this application is that the durability of the cable is not affected by deterioration of its strong core by virtue of the aggressive mechanical action of particles of the sea bed which might penetrate the cable and reach its core. For this purpose a layer (3) to protect the core (1) comprising a strip of polymer material placed in helical fashion which permits the passage of water and prevents the passage of particles of the sea bed towards the core (1) is placed between the cable core (1) and its outer braided protective layer (2).
Abstract:
Das Sicherheits-Bergseil (1) weist einen aus mehreren Kernseilen (2) bestehenden Seilkern auf. Zur Verbesserung der Reissfestigkeit dieses Seils (1) umschliesst der Seilkern schlauchartig mindestens einen über die gesamte Länge des Seiles (1) sich erstreckenden Hohlraum (3). Der letztere ist dabei mittels mindestens eines mindestens in radialer Richtung des Seiles (1) gesehen gummielastischen Füllmaterials oder -körpers ausgefüllt, welcher z.B. beim Ziehen des Seils (1) über eine Kante und unter starker Zugkraft eine beachtliche momentane Abplattung des Seilquerschnitts beim Ziehen über die Kante und damit eine erheblich breitere Abstützung dieses Seils (1) an einer solchen Kante bewirkt.
