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.

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.
