Elevator systems comprising: an elevator cabin and a drive for moving the elevator cabin along an elevator shaft, and a cable for supplying electrical power and/or control signals to the elevator cabin. The elevator system further comprises a cable protection system (6), attached to the elevator cabin and comprising a cable support (60) for holding a portion of the cable, an actuator (8) operatively connected with the cable support; and a restraint (7) configured to retain the actuator or the cable support up to a threshold force such that when the cable exerts a force on the cable support that is higher than the threshold force, the actuator (8) pushes against a switch (9) to stop the drive.

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 method for detecting deterioration of a plurality of wire ropes is provided. Each of the wire ropes extends over a conductive sheave in parallel. The wire ropes define a measurement length extending between one end of the wire ropes and contact points of the wire ropes with the conductive sheave. The method comprises measuring the resistance through a conductive path passing through the measurement lengths of two of the wire ropes and the conductive sheave and detecting the deterioration of the wire ropes from the measured resistance.

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.

An elevator system capable of reducing the overall installation area of elevators in a building while ensuring the number of passengers in the elevator. The elevator system arranges first and second elevator cars in a single elevator hoistway, having, at a lower portion of each of the first and second elevator cars, respectively, a pair of undercar pulleys are positioned to turn ropes vertically on the outer sides of the first and second elevator cars and horizontally at the bottom, where the arranging direction of the pair of the under-car pulleys of the first elevator car intersects with the arranging direction of the pair of under-car pulleys of the second elevator car when projected onto a horizontal plane.
