Abstract:
A passenger conveyor is provided, the conveyor includes a first stationary structure and a second stationary structure; a step (18) positioned between the first stationary structure and the second stationary structure, the step has a tread (42) with a tread surface; and a skirt (40) secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge (54); wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.
Abstract:
A system and method of measuring and diagnosing the ride quality of an elevator system, including (a) operating the mobile device to acquire ride quality data, (b) operating the mobile device to transmit ride quality data to an external computing device, (c) operating the external computing device to compare the acquired ride quality data to pre-determined system data to create performance data, (d) operating the external computing device to perform a ride quality diagnostics based at least in part on the performance data, and (e) operating the external computing device to transmit the ride quality diagnostics to the mobile device.
Abstract:
A belt for suspending or driving an elevator car includes a plurality of wires arranged into one or more cords; and a jacket substantially retaining the one or more cords. At least one of the one or more cords includes a plurality of non-load bearing filler filaments interposed between adjacent wires of the plurality of wires. An elevator system includes an elevator car, one or more sheaves, and one or more belts operably connected to the car and interactive with the one or more sheaves for suspending or driving the elevator car. Each belt of the one or more belts includes a plurality of wires arranged into one or more cords and a jacket substantially retaining the one or more cords. At least one of the one or more cords includes a plurality of non-load bearing filler filaments interposed between adjacent wires of the plurality of wires.
Abstract:
An exemplary device for use in an elevator system (20) includes a leveler (40) that is configured to move into and selectively maintain a vertical position in an elevator hoistway. A controller (48) is configured to determine a desired vertical position of the leveler (40) based upon a corresponding intended position of an elevator car (22). The controller (48) is configured to adjust a vertical position of the leveler (40) responsive to a difference between an actual vertical position of the leveler and the desired vertical position.
Abstract:
Embodiments are directed to determining that an elevator car of an elevator system is approaching a landing, obtaining, by a controller, a value for at least one parameter associated with the elevator system based on the determination that the elevator car is approaching the landing, determining that the elevator car arrives at the landing within a threshold distance, determining, by the controller, when to engage in at least one of a brake cycling operation and a power cycling operation based on the value for the at least one parameter and based on determining that the elevator car arrives at the landing within the threshold distance, and initiating the at least one of a brake cycling operation and a power cycling operation at a time corresponding to the determination of when to engage in the at least one of a brake cycling operation and a power cycling operation.
Abstract:
An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.
Abstract:
A method of tension adjustment for a load bearing member of an elevator system includes measuring a load on a load bearing member of an elevator system via a load cell operably connected to the load bearing member, the load cell and the load bearing member connected to an elevator car disposed in a hoistway, the measured load equated with a tension of the load bearing member. The measured tension to a preselected range and an adjustment of the tension of the load bearing member is determined. Adjustment instructions are communicated to a handheld electronic device and the communicated adjustment instructions are performed thereby adjusting the tension of the load bearing member to within the preselected range.
