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.

Elevator suspension and/or driving assembly having at least one traction surface comprising exposed weave fibers

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.

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.

System and method of measuring and diagnosing ride quality of an elevator system

A method includes determining that an elevator car is arriving at a landing at which re-leveling is anticipated; upon the elevator car arriving at the landing at which re-leveling is anticipated, initiating the at least one of a brake cycling operation and a power cycling operation to reduce elevator car sag at the landing; monitoring transfer of weight to or from the elevator car at the landing over a period of time; terminating the at least one of the brake cycling operation and the power cycling operation upon at least one of (i) the transfer of weight to or from the elevator car at the landing over the period of time being less than a threshold and (ii) the elevator car sag at the landing meeting a sag threshold.

Brake operation management in elevators

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.

A passenger conveyor includes a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step has a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.

Skirt for passenger conveyer

A piston-type passenger conveying system includes at least three cabs to move between two floors. A control moves the cabs such that a cab is always waiting at each of said floors, and another cab is always moving to a floor. In this way, the system achieves the passenger flow benefits of an escalator with the inherent benefits of an elevator system.

Piston-type passenger conveying system

A rotating passenger conveying system includes a central rotating column which drives a number of cabs to rotate about an axis. The cabs are also movable along the axis between a first and second floor. The central column rotates continuously, and the cabs are cyclically moved between the two floors. Passengers can enter a cab at one of the floors, and cab will then rotate to a movement zone. In the movement zone the cab will move to the other floor. The movement and flow of passengers in this system is continuous, and thus, the throughput of passengers in the rotating passenger conveying system is closer to an escalator system than to an elevator.
