Abstract:
A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.
Abstract:
The invention discloses a tension absorbing means produced from a flexible strand (1) that can only be loaded under tension, the tension absorbing means possessing the advantages of a chain formed from strand material, yet at the same time being able to be produced in a simple and cost-effective manner. To this end, in a means of this kind, the strand (1) is laid into two or more loop sections (S1,…, Se). At the same time, proceeding from the beginning (A) of the strand (1) towards every preceding loop section (S1,…, Se-1) arranged at an offset towards the beginning (A), a succeeding loop section (S2,…, Se) arranged at an offset towards the end of the strand (1) follows until the last loop section (Se) has been reached. Furthermore, every loop section (S1,…, Se) has a loop (S) which delimits a loop opening (0). Finally, at least one chain (M1,…, Me) is formed from the strand (1) as a result of a succeeding strand section (S2,…, Se) being guided by its loop (S) through the loop opening (0) of a preceding loop section (S1,…, Se-1) arranged adjacently thereto.
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:
A loop rope assembly includes a main rope segment having a plurality of rope strands and first and second ends, a first end loop provided on the first end of the main rope segment, a second end loop provided on the second end of the main rope segment and at least one intermediate loop defined by at least one of the rope strands. A linkable loop rope system that includes at least two loop rope assemblies fastened together by a coupling mechanism operable to releaseably couple the rope assemblies for use in securing large and/or irregular shaped objects on a transport vehicle or a tarp or cover on such objects during transport.
Abstract:
The invention relates to a braided rope for bend-over-sheave applications consisting essentially of n braided primary strands being made of polymeric filaments, which rope has an oblong cross-section with aspect ratio in the range 1.2 - 4.0. Such a rope shows markedly improved service life performance in cyclic bend-over-sheave applications. The invention also relates to the use of a braided rope according to the invention as a load-bearing member in bend-over-sheave applications; and to a system comprising such a rope and at least one sheave with a groove, the dimensions of which groove are adapted to the rope dimensions.
