A system and method for detecting elevator maintenance behaviors in an elevator hoistway. The system of the invention comprises: an emitting component for emitting wireless signals including channel state information (CSI) into the elevator hoistway; a receiving component for receiving the CSI from the elevator hoistway; and a maintenance behavior detecting device, which comprises: a memory that stores CIS image recognition models constructed corresponding to the predefined elevator maintenance behaviors and a corresponding computer program executable on a processor, and the processor configured to be able to execute the computer program to implement the following operations: processing data of the received CSI to obtain a CSI image corresponding to the elevator maintenance behavior detected, and inputting the CSI image to the CSI image recognition model for analysis and processing so as to detect the elevator maintenance behavior.

According to an aspect, there is provided an elevator system comprising an elevator car configured to move in an elevator shaft; a main safety controller comprising a main safety output and a secondary safety output, wherein the main safety output is configured to control machinery brakes of the elevator car; and a secondary safety circuit connected to the secondary safety output and arranged in the elevator car and comprising at least one safety contact configured to control stopping means arranged in the elevator car; wherein when the at least one safety contact is triggered the secondary safety circuit is configured to control the stopping means to cause stopping of the elevator car.

A system for detecting a presence of a person in a hoistway, having: one or more controllers configured to authenticate the person in the hoistway; the one or more controllers being operationally connected to an elevator car in the hoistway and configured to determine whether the person is within a predetermined distance of the elevator car from a signal emitter on the person; wherein when the person is within the predetermined distance of the elevator car, the one or more controllers is configured to transmit a feedback request to the person and stop the elevator car unless the one or more controllers receives feedback to the feedback request within a predetermined period of time.

An elevator car (102) including at least one barrier (110) extending from an external surface (106, 108) of the elevator car (102). The elevator car (102) further includes a switch (208) connectable in series with a safety chain circuit. The at least one barrier (110) is configured to be displaced from a first position (202) to a second position (204) upon contact with an object (120), such that the displacement to the second position (204) opens the switch (208) to initiate an emergency stop procedure of the elevator car (102).

An elevator safety includes a barrier (108) for installation on an external upper surface (106) of an elevator car (102) and a sensor. The sensor is configured to detect a change in the barrier (108) and the system is configured to produce a safety signal when a change in the barrier (108) is detected by the sensor. The sensor may be configured to detect a movement of at least part (316; 426; 548) of the barrier (108). The sensor may be configured to detect a change in the load applied to at least part (626; 726) of the barrier (108). The sensor may be configured to detect a change in resistance in at least part of the barrier (108).

Safety systems and methods for elevator systems include an elevator car configured to travel along an elevator shaft, a pit at a bottom of the elevator shaft, and a governor having an energizable actuator configured to be continuously energized from a time of activation to a time of reset, the governor configured to stop downward movement of the elevator car along the elevator shaft after the time of activation until the time of reset, with energizing of the energizable actuator being initiated from an electrical trigger mechanism proximate the pit of the elevator shaft.

An elevator system (1) including at least one refuge space (7, 8) and at least one light curtain (9). The at least one light curtain (9) is configured to detect at least one object in the at least one refuge space (7, 8) and produce at least one safety signal (21) indicating the presence of the at least one object in the at least one refuge space (7, 8). The system can be used to improve the safety in the at least one refuge space (7, 8) in the event that the usual safety procedures have either failed or not been followed.

Disclosed is an elevator system, including a hoistway; an elevator car in the hoistway; sensors in the hoistway operationally coupled to the elevator car and configured to capture sensor data indicative of a person being in the hoistway, and a processor configured to determine from the sensor data that the person is in the hoistway; and wherein the elevator car is configured to reduce speed or stop when the processor determines the person is in the hoistway.

Elevator access systems are provided. The elevator access systems include a bushing having a keyway, a plunger disposed within the bushing and movable relative thereto, a lever operably connected to the plunger, and a removable plug located within the keyway of the bushing, wherein the removable plug urges the plunger and the lever into a first position, and upon removal of the removable plug, the plunger and the lever move to a second position, wherein in the second position the plunger is accessible to operate the lever.

An elevator car has a pivotable balustrade mounted on a roof of the elevator car and which can be pivoted between a folded-down position and an erected position. To secure the erected position, the balustrade has a locking mechanism by which the balustrade can be locked via a latching connection during a pivoting movement to produce the erected position. The balustrade includes a two-part post with a lower post part and an upper post part, the upper post part being pivotably fastened to the lower post part and on which the locking mechanism is arranged. A latching element of the locking mechanism is mounted vertically on the lower post part so as to be displaceable to a limited degree. The locking mechanism further has an actuating element in the form of a foot pedal or a lever for unlocking the locking position.
