Depth cameras may be placed within an elevator car hoistway to capture depth images of the elevator rope. 3D sensing software may be used to identify the rope within the depth images and assign tracking points to locations along the rope. Tracked images are saved over time and compared to prior tracked images to determine the movement of tracked points between images. Movement of tracked points may be used to determine the velocity, acceleration, frequency of wave motion, and other characteristics of the rope during a period of time. When measured characteristics exceed specified thresholds, the system may take one or more actions to mitigate the undesirable behavior or provide notification of the undesirable behavior.

A composite elevator belt includes at least one load carrier strand extending in a longitudinal direction, a core layer encasing the at least one load carrier strand, and a first plurality of teeth extending transversely across a top surface of the core layer. The first plurality of teeth includes a root portion associated with the core layer and a tip portion. The composite elevator belt further includes a first jacket layer extending in the longitudinal direction, at least the tip portion of the first plurality of teeth being associated with a bottom surface of the first jacket layer.

Composite elevator belt

A suspension and transmission device for use with an elevator system comprises one or more strips that provide load carrying, transmission or traction, and load carrying redundancy or safety functions for the elevator system. In one version a single strip comprised of polymer and composite materials provides these functions. In another version multiple strips comprised of polymer and composite materials provide these functions. In another version, a strip comprises a hollow interior portion. In another version one or more strips incorporate materials that can be detected when using the strip to monitor the condition of the one or more strips.

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.

An end termination for an elevator system including at least two opposing outer plates connected to one another, at least two opposing guiding elements held between the outer plates, and at least two opposing wedges extending between the guiding elements and configured to clamp an elevator belt therebetween. Upon application of a belt pull force to the elevator belt, the wedges are deformed towards one another to increase a clamping force on the elevator belt.

An end termination for an elevator system may include an outer clamping member, an inner clamping member having a dimension in a first plane that is greater than a dimension in a second plane, the first plane being spaced from the second plane along a longitudinal axis of the end termination, the inner clamping member coaxially disposed in the outer clamping member, a housing holding the inner clamping member and the outer clamping member therein, and a tightening arrangement to clamp a belt between the inner clamping member and the outer clamping member.

A motor for use with an elevator system may include a housing, a motor shaft surrounded by the housing and having at least a first end extending outward from the housing, a motor body arranged around a central portion of the motor shaft and positioned within the housing, at least one sheave positioned at the first end of the motor shaft and rotatable with the motor shaft, and a braking system positioned at a first end of the housing. The braking system may include a brake rotor connected to and rotatable with the motor shaft and closing an axial opening at the first end of the housing, a brake shoe positioned at the first end of the housing, and a brake actuator configured to selectively move the brake shoe between a brake position in which the brake shoe is in contact with the brake rotor to resist rotation of the motor shaft and a rotation position in which the brake shoe is free from contact with the brake rotor.

A system and method for controlling the movement of an elevator is provided. The elevator controller directs the operation of the elevator and receives information from the elevator system to calculate a brake profile. The elevator system transmits the brake profile to a master controller. The master controller selectively actuates the brakes to apply a braking force configured to generate the brake profile. The system and method may include local controllers, each configured to actuate a respective brake, wherein the master controller selectively directs the local controllers to generate a brake force commensurate with the braking profile.

Elevator with master controller

An elevator arrangement includes two or more hoistways, at least one more elevator car than a total number of hoistways, and at least one more belt system than the total number of hoistways. At least one belt system may be provided between each pair of hoistways. At least one elevator car may be provided in each hoistway. Each elevator car may be connected to at least one belt system. The belt systems may provide a direct transfer of mechanical energy between the elevator cars. As a first elevator car moves downward in a first hoistway, mechanical energy may be generated via the belt systems to lift a second elevator car upwardly in a second hoistway.

Arrangement and method to move at least two elevator cars independently in at least one hoistway

A hydraulic-boosted rail brake is provided for use with an elevator having a guide rail. The rail brake includes a braking plate having friction material, a spring package in communication with the braking plate, a hydraulic cylinder, a piston housed at least partially inside the hydraulic cylinder, and a brake controller. The braking plate is selectively movable relative to the guide rail, and the spring package biases the friction material to interact with the guide rail to cause braking. The piston is in communication with the braking plate and is selectively: (a) movable in a release direction to diminish or overcome force from the spring package; and (b) movable in an engage direction to supplement the force from the spring package. The brake controller selectively causes the piston to move in the release direction and in the engage direction.

A jumper has a connector and a housing. The housing at least partially encloses a processor in data communication with a non-transitory memory, a global positioning system, a rechargeable battery, and a networking device. The memory comprises software instructions that, when executed by the processor, perform steps for wirelessly transmitting data to a mobile device over a network. The data indicates a jumper identification number, a location of the jumper, and a duration after which the jumper will automatically deactivate. The steps performed include the step of wirelessly outputting an alert to the mobile device when the mobile device is at a first distance from the jumper. The first distance is settable using the mobile device. The alert causes the mobile device to at least one of vibrate and ring.

A braking device () for braking a lift car which moves relative to a lift shaft, having at least one braking module () which is provided in order to interact with a device, and having a catch () which can be adjusted between two operating positions (), wherein the catch (), in a first operating position (), is connected to the at least one braking module () such that the catch () transmits a release force () to the at least one braking module (), and wherein the catch (), in a second operating position (), is separated from the at least one braking module (), and the at least one braking module () is therefore in contact with the device.
