Abstract: 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.

Abstract: 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.

Abstract: An elevator belt position tracking system including a magnetic field producer located in operational proximity to an elevator sheave carrying an elevator belt to produce a magnetic field encompassing the elevator belt, a magnetic sensor located in operational proximity to the sheave carrying the elevator belt, the magnetic sensor comprising a plurality of signal channels spaced apart along a width of the magnetic sensor. The respective signal channels are activated by the proximity of the elevator belt to the signal channels as the elevator belt passes through the magnetic field generated by the magnetic field producer to determine a lateral position of the elevator belt on the sheave.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system and method relate to magnetic hoisting member monitoring in an elevator system having an elevator car, a hoisting motor, and a magnetic hoisting member. A monitoring system is used that includes a magnetic field producer, a giant magneto-resistance sensor, a housing unit, and an indicator system. The housing unit is structured to position the magnetic hoisting member of the elevator system relative to the magnetic field producer and the giant magneto-resistance sensor.

Abstract: One or more drum winches rotate suspension members to raise and lower an elevator car within a hoistway. Support structures on opposite sides of the hoistway support the winch(es) or drive sheave(es). The suspension members may be configured in a dual closed loop system, a single open loop system, or a single closed loop system. The suspension members may be flat or toothed members. A synchronization device may be used to control the winch(es) or drive sheave(es) to maintain the level of the elevator car.
