    Abstract: An electrical inspection system for an elevator load bearing member includes an electrically conductive, low resistance wrap located at the load bearing member, contacting the load bearing member around a circumference of the load bearing member. An inspection unit is configured to apply an electrical current through the load bearing member and determine an electrical resistance of the load bearing member, and is electrically connected to the load bearing member at the wrap to distribute electrical current uniformly therethrough. A method of determining an electrical resistance of a load bearing member of an elevator system includes applying an electrically conductive low electrical resistance wrap entirely around a circumference of the load bearing member. An inspection unit is connected to the load bearing member at the wrap. An electrical current is applied through the wrap into the load bearing member to determine an electrical resistance of the load bearing member.

    Abstract: A method of detecting a stuck car or a stuck counterweight in an elevator system having a machine for imparting motion to the car and counterweight includes sensing a car side suspension member tension, T1; sensing a counterweight side suspension member tension, T2; determining a traction ratio in response to a relationship between T1 and T2; and determining a stuck car or a stuck counterweight if the traction ratio violates a limit.

    Abstract: A system and method for monitoring a first wire rope and a second wire rope is provided. The first and second wire ropes each include a contact portion that contacts a sheave, a first end portion, and a monitored portion that extends between the contact portion and the first end portion. The sheave electrically connects the contact portions of the first and second wire ropes. The system includes a controller that is electrically connected to each of the first and second wire ropes to form a circuit with the monitored portions of the first and second wire ropes. The controller selectively applies a signal to the monitored portions of the first and second wire ropes and determines an electrical characteristic thereof. The controller uses the determined electrical characteristic to determine a condition of the first and second wire ropes.

    Abstract: An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.

    Abstract: An elevator system includes one or more elevator cars configured to travel along a hoistway. One or more rails extend along the hoistway and are operably connected to the one or more elevator cars to guide the one or more elevator cars along the hoistway. Each rail of the one or more rails includes a plurality of rail segments arranged end to end. Each rail segment is affixed to a hoistway wall to transfer vertical loads from the rail segment to the hoistway wall. Each rail segment is secured to the hoistway wall via a plurality of rail support brackets. The vertical loads are transferred from the rail segment to the hoistway wall via at least one rail support bracket of the plurality of rail support brackets.
