A termination device for a suspension member of an elevator system includes a termination housing, and two wedge assemblies located in the termination housing. The wedge assemblies are interactive with a suspension member end positioned between the two wedge assemblies to apply a clamping force to the suspension member end in response to an axial load acting on the suspension member end. Each wedge assembly includes a wedge and a biasing element operably connected to the wedge to bias a position of the wedge along a suspension member axis direction.

A rope lifting tool for belt-shaped ropes comprises a first guide for guiding the rope lifting tool along a first guide rail; a second guide for guiding the rope lifting tool along a second guide rail; an upright plate, and an inclined plate at an acute angle relative to the upright plate. The upright plate and the inclined plate have a wedge shaped space between them. A plurality of wedge members are placed adjacent each other inside the wedge-shaped space. A rope gap for receiving an end of a belt-shaped rope is formed between each wedge member and the upright plate, which rope gap is narrowable by wedging of the wedge member in the wedge shaped space. A rope lifting arrangement includes the rope lifting tool.

An elevator system has a car and a suspension device, wherein the car is least partially carried by the suspension device. The suspension device includes several electrically conductive tension members that are arranged parallel to one another and are essentially enclosed by a jacket. The suspension device is attached to suspension device mounting fixtures, wherein the suspension device mounting fixtures each include a housing and a clamping element. The housing and the clamping element have clamping surfaces between which the suspension device is clamped. The clamping element and/or the housing is made of an electrically insulating material.

The invention relates to a rope terminal assembly of an elevator fixing an elevator rope to a fixing base such as an elevator unit, said elevator being suitable for transporting passengers and/or goods, said assembly comprising an elevator rope, whose width is larger than its thickness in a rope transverse direction, with at least one end comprising a first member with a first end face and a second member with a second end face, a wedge element, a wedge housing, the rope terminal assembly comprising a rope gap through which said elevator rope passes and said wedge element is arranged to wedge between the first member with the first end face and the second member with the second end face of the elevator rope thus locking said elevator rope in the gap, and an elevator.

An elevator end termination for an elevator belt includes a wedge housing, a segmented wedge disposed axially within the wedge housing. The segmented wedge includes at least two wedge members spaced apart from one another to define a space therebetween. At least one pressure sensor is disposed in the space defined between the at least two wedge members. The at least one pressure sensor registers compressive pressure exerted between the at least two wedge members. The at least two wedge members may include a pair of adjacent longitudinally-extending wedge members, and a wedge crown adjacent a first end of each of the longitudinally-extending wedge members and separated therefrom by a transversely-extending space. The space is a longitudinal slot between the adjacent wedge members.

A termination device for a suspension member of an elevator system includes a housing including a socket defined by two face plates and two side plates. At least one of the face plates and at least one of the side plates are integrally formed. A wedge is receivable within the socket with the suspension member. The wedge is configured to cooperate with the housing to apply a clamping force to the suspension member in response to an axial load acting on the suspension member.

A clamp for open ended flat belts. The clamp has a tapered housing with an aperture at a first end providing access to the housing interior and a second open end also providing access to the interior. A tapered wedge is removable and replaceable from the interior of the housing, the wedge having a first end and a radiused second end and having a surface comprising alternating ribs and lands. The clamp includes a lock having a concave surface similar to the radiused second end of the tapered wedge. The housing may have a removeable and replaceable side wall providing access to the interior.

A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.

A method and device detect non-uniform and uniform deterioration states in an elevator suspension member having first and second groups of electrically conductive cords. First ends of the groups are electrically connected to an alternating voltage generator arrangement and second ends are electrically connected to each other through first and second resistors via a neutral point at which electrical resistances of the groups are the same in a non-deteriorated state of the suspension member. The method includes: applying first and second alternating voltages to the first end of the first and second groups, respectively; determining a neutral point voltage between the neutral point and an electrical reference potential; determining difference voltages between first and second difference measurement points located between the second ends of the groups and the respective resistors; and determining the deterioration state based on both the determined neutral point voltage and the determined difference voltage.
