The invention concerns the field of marine ropes, and more specifically a marine rope (1) comprising a plurality of cores (2; 2a, 2b), an individual coating (3) around each core (2; 2a, 2b), and a permeable protective sheath (4) around the plurality of cores (2; 2a, 2b). Each core (2; 2a, 2b) comprises a fiber strand or braid and each individual coating (3) is watertight and has a melting temperature lower than that of the corresponding core and an elongation at break greater than that of the corresponding core.

A lifting member for an elevator system includes a rope formed from plurality of load carrying fibers extending along a length of the lifting member. The plurality of load carrying fibers including a plurality of aromatic polyester based fibers. A coating layer at least partially encapsulates the rope. An elevator system includes a hoistway, an elevator car disposed in the hoistway and movable therein, and a lifting member operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The lifting member includes a rope formed from plurality of load carrying fibers extending along a length of the lifting member. The plurality of load carrying fibers including a plurality of aromatic polyester based fibers. A coating layer at least partially encapsulates the rope.

Provided herein is an electrodeposition apparatus for producing long polymeric threads, yarns, or ropes. A method of preparing long polymeric threads, yarns or ropes also is provided.

A steel cord for the reinforcement of elastomer products such as elevator belts, conveyor belts, synchronous or timing belts or hoses or tyres is presented. The steel cord comprises strands and monofilaments made of steel filaments. The strands themselves are also made of steel filaments twisted together. The strands form the outer layer of the steel cord. The monofilaments are twisted into the cord with the same lay length and direction as the strands and are positioned in the valleys between the strands on the radial outer side of the steel cord. The steel cord has the advantage that it has a better fill factor and a rounder aspect. Furthermore the monofilaments may act as an early wear indicator of the elastomer product.

The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

An elevator tension member is presented that has one or more steel cords as strength members that are encased in a jacket of thermoplastic polyurethane elastomer. The thermoplastic polyurethane elastomer is selected on the basis of its thermal properties in that the glass transition temperature of the hard phase (Tg HS) is above 90° C. In preferential embodiments that thermoplastic polyurethane elastomer has a crystallisation temperature (Tg) that is at least 20° C. higher than Tg HS. In other preferential embodiments the sum of Tg HS and Tc is higher than 200° C. Such thermoplastic polyurethane elastomers exhibit an unexpected increase in useful lifetime when compared to conventionally used polyurethanes. Moreover the invention provides a simple method to select an appropriate thermoplastic polyurethane elastomer.
