Rope, elevator arrangement and elevator
The invention relates to a belt-shaped rope of an elevator having opposite lateral sides facing in thickness direction of the rope, at least one of the lateral sides being shaped to have elongated wedge-shaped ribs that are disposed adjacent each other in width direction of the rope and extend parallel with the longitudinal direction of the rope, each said wedge-shaped rib having a first flank face and a second flank face that are at an acute angle relative to each other, and the surface material of said flank faces has shore A hardness more than 85 and less than 100. The invention also relates to an elevator arrangement as well as to an elevator, implementing the aforementioned belt-shaped rope.
Elevator system belt
A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of basalt fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the plurality of tension members. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a plurality of basalt fibers to enhance temperature resistance of the tension member. A jacket material at least partially encapsulates the plurality of tension members.
Elevator belt, method for producing such an elevator belt, and elevator system having such a belt
An elevator belt comprising a belt body made of a first material, a reinforcement arrangement having at least one reinforcement provided on the belt body, and a tube arrangement made of a second material having at least one tube, the at least one reinforcement of the reinforcement arrangement being provided in a tube of the tube arrangement.
Wear detection for elevator system belt
A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of fibers. A metallized coating layer is applied to at least a portion of an outer surface of at least one tension member of the plurality of tension members. The metallized coating has a coating electrical conductivity greater than a tension member electrical conductivity of the at least one tension member. A jacket material at least partially encapsulates the plurality of tension members and the metallized coating layer.
STEEL WIRE ROPE, COATED STEEL WIRE ROPE AND BELT COMPRISING STEEL WIRE ROPE
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope contains a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during used. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. The use of this ‘sacrificial core’ results in a higher residual breaking load after use.

Elevator suspension and/or driving assembly having at least one traction surface comprising exposed weave fibers
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.
Elevator, suspension body for the elevator, and manufacturing method for the suspension body
A suspension body for an elevator includes a core having a belt-like shape, and a covering layer covering at least a part of an outer periphery of the core. The core includes a load bearing layer. The load bearing layer is formed of an impregnation resin and a plurality of high-strength fibers. Further, the load bearing layer is divided into a plurality of segment layers arranged apart from each other in a thickness direction of the core. An intermediate layer made of a material different from that for the load bearing layer is interposed between the segment layers adjacent to each other in the thickness direction of the core.
