Abstract: An elevator rope guide system comprises a plurality of rope guides for restricting the swaying of at least one main rope and a plurality of stop mechanisms each configured to stop a corresponding rope guide. The rope guides are located above an elevator car and/or counterweight and are vertically movable along a hoistway. The stop mechanisms are positioned at different intermediate heights along the hoistway. The elevator rope guides are collected by the elevator car or counterweight as the elevator car or counterweight moves up and are stopped by a corresponding stop mechanism as the elevator car or counterweight moves down.

Abstract: An exemplary building traffic analyzer for an elevator includes: a video camera arranged in an elevator car; a traffic analyzer unit for collecting traffic data of passengers through the video camera; and a data storage unit for storing the traffic data of passengers collected by the traffic analyzer unit. The traffic analyzer unit is configured to identify and track each passenger for collecting the traffic data of each passenger including a boarding floor with boarding time and a destination floor with exiting time. The building traffic analyzer is configured to be temporarily attachable in the elevator car, such as on the ceiling or proximity to the elevator control panel.

Abstract: A method for detecting trapped passengers in an elevator car (1) comprises collecting a sound in the elevator car (1) when an elevator controller (2) detects any failure of an elevator and comparing the level of the sound a threshold level. The method further includes automatically making a call to a help desk (26) and taking pictures in the interior of the elevator car (1) when the level of the sound exceeds the threshold level.

Abstract: A monitoring system for a passenger conveyor is provided. The passenger conveyor includes a motor for driving the passenger conveyor and an inverter for supplying current to the motor. The monitoring system includes a current sensor for detecting the current supplied to the motor; a temperature sensor for detecting the temperature of the motor; a data collecting device for receiving detected data from the current sensor and the temperature sensor; and a controller connected to the data collecting device. The controller is configured to calculate an idle operation motor torque during an idle operation of the passenger conveyor based on current and temperature detected during the idle operation; and determine that a fault exists in the passenger conveyor when a difference between the idle operation motor torque and a reference motor torque exceeds a predetermined threshold.

Abstract: A handrail friction checking device comprises a handrail gripper for gripping the handrail and movable together with the handrail, a spring with one end of the spring being fixed and the other end being connected to the handrail gripper so that the spring can apply a spring force which is opposed to the direction of handrail movement to the handrail gripper when the handrail gripper moves along with the handrail and a sensor which is disposed in a way that it is distanced from the handrail gripper and can be triggered by the handrail gripper when the handrail gripper moves along with the handrail.
