A belt (30) for suspending and/or driving an elevator car (14) includes a plurality of tension elements (32) extending longitudinally along a length of the belt, at least one tension element of the plurality of tension elements having one or more tension element coating layers (46) applied thereto. A plurality of fibers are interlaced with the plurality of tension elements forming a composite belt structure. A belt coating (44) at least partially encapsulates the composite belt structure.

Provided is a rope including a load supporting member and a covering member covering an outer periphery of the load supporting member. The load supporting member includes: an impregnation material and reinforcement fiber bodies, which continuously extend in a longitudinal direction of the rope, are embedded in the impregnation material, and are configured to support a load acting in the longitudinal direction. The reinforcement fiber bodies include corrugated reinforcement fiber bodies which have, at least in part, a corrugated shape in a section parallel to the longitudinal direction. The corrugated reinforcement fiber bodies have such a length that a total length thereof given when the corrugated reinforcement fiber bodies are straightened is equal to or larger than 1.1 times a total length of the load supporting member.

The invention relates to an elevator apparatus, comprising: a shaft, an elevator car vertically movable in the shaft, one or more ropes connected with the car, and a controller for controlling movement of the car. In order to detect sway in one or more elevator ropes connected with the car, the apparatus comprises at least one sensor unit arranged in the elevator shaft to detect sway and to produce a control signal indicating to the controller the detected sway. The controller compares the detected sway to a predetermined limit and prevents movement of the elevator car when sway reaches the predetermined limit.

The invention discloses: —a drive belt safety device (20) including a belt retaining portion (22) and a wedging portion (24) operably coupled to the belt retaining portion (22), wherein the wedging portion (24) includes a geometry configured to wedge between a drive belt (16) and a pulley (12, 14); and —a method of securing a drive belt system (10), the drive belt system (10) comprising a pair of pulleys (12, 14) configured to rotate and a drive belt (16) disposed around each of the pulleys (12, 14), the method comprising the steps of placing at least one drive belt safety device (20) adjacent to a pulley (12, 14), and securing a portion of the drive belt (16) to the at least one drive belt safety device (20).

A belt for use as for example an elevator belt, flat belt, synchronous belt or toothed belt comprises steel strands held in parallel by a polymer jacket. The steel strands have a diameter ‘D’ and are separated by a pitch ‘p’. The ratio of diameter ‘D’ over pitch ‘p’ is larger than 0.55. Such belt arrangement prevents the cutting of the polymer jacket between strand and pulley and abates the noise generation during use. The belts are best built with a type of parallel lay strands particularly designed for use in a belt. These strands do not show core migration during use of the belt.

A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave.

A people conveyor (2) comprises at least one belt (4) extending in a longitudinal conveying direction, a plurality of webs (6) attached to the belt (4), and a plurality of transportation elements (14). Each of the transportation elements (14) comprises at least one connection portion (20). The connection portions (20) extend laterally from the transportation elements (14) and are configured for being connected with at least one of the webs (6) for attaching the respective transportation element (14) to the belt (4).

An elevator installation and method to passively and reliably generate electrical energy while the elevator installation is in operation utilizes piezoelectric layers. The elevator installation includes an elevator car, a tension member for supporting and moving the elevator car, and a pulley engaging with the tension member wherein the pulley has a piezoelectric layer positioned such that any force imparted to the pulley during engagement with the tension member compresses the piezoelectric layer. As the tension member is driven to move the elevator car up and down along an elevator hoistway it also engages with the rotating pulley. Force imparted to the pulley during this engagement with the tension member compresses the piezoelectric layer which consequently generates electrical energy.

An elevator installation has a car at least partially supported by a support including several electrically conductive tension-bearing elements, which elements are arranged parallel to each other and which are substantially surrounded by a jacket. The support is fastened to fastening devices, wherein the fastening devices each include a housing and a clamping element. The housing and the clamping element each have clamping surfaces, between which surfaces the support is clamped. An electrically insulating material is arranged between at least one side of the support and the clamping surfaces arranged thereon. The electrically insulating material electrically isolates the support from the housing or the clamping element or both.

In a rope of a lifting device, particularly of a passenger transport elevator and/or freight transport elevator, the width of which rope is greater than the thickness in the transverse direction of the rope, which rope includes a load-bearing part in the longitudinal direction of the rope, which load-bearing part includes carbon-fiber reinforced, aramid-fiber reinforced and/or glass-fiber reinforced composite material in a polymer matrix, and which rope includes one or more optical fibers and/or fiber bundles in connection with the load-bearing part and the optical fiber and/or fiber bundle is laminated inside the load-bearing part and/or the optical fiber and/or fiber bundle is glued onto the surface of the load-bearing part and/or and that the optical fiber and/or fiber bundle is embedded or glued into the polymer envelope surrounding the load-bearing part, as well as to a condition monitoring method for the rope of a lifting device.
