Abstract:
The invention relates to a support element system, in particular for elevators, having at least one support element (1) comprising two load-bearing traction members (11) disposed horizontally adjacent to each other, and enclosed in a common elastomeric encapsulation (12) separating the two traction members, wherein the traction members each comprise an opposite impact direction (z, s) and have a drive disc (2) for transmitting a drive force to the at least one support element, wherein the drive disc comprises a contoured traction surface (4) having two contact surfaces (5, 6) interacting with the support element (1) for transmitting the drive force.
Abstract:
The invention concerns a cable comprising a bundle of substantially parallel stretched strands (3) contained in at least a plastic protective sheath section (1). The plastic material of the sheath section extends between the strands to form a coherent matrix for spacing the strands. The invention is particular useful as prestressed cable, bracing guy or carrying cables for suspension bridges.
Abstract:
A rope having a cut-resistant jacket which includes a core comprised of a plurality of sub-ropes. The sub-ropes may be in a parallel strand configuration. The sub-ropes and the strands thereof may be made of fibers of a synthetic material, such as polyester, nylon, polypropylene, polyethylene, aramids, or acrylics. A cut-resistant jacket surrounds the core and is made from a material that has increased strength and/or abrasion resistance over the material of the core. The cut-resistant jacket may comprise steel wires and may further comprise braided steel wires or rope. The braided steel wires or rope may be covered with a plastic material for increased corrosion resistance. A filter layer may be disposed between the core and the cut-resistant jacket and may be wrapped around an outer surface of the core prior to the cut-resistant jacket being formed.
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:
An exemplary elongated elevator load bearing member of a traction elevator system includes a plurality of tension elements. A plurality of weave fibers transverse to the tension elements are woven with the tension elements. The weave fibers define at least one traction surface of the load bearing member.
