摘要： According to an aspect, there is provided a method for condition monitoring of inductive braking device of an elevator car in an elevator shaft, the method including determining that the elevator car is empty; determining that doors of the elevator car are closed; causing electromechanical brakes to hold the elevator car stationary in the elevator shaft; causing actuation of a braking condition for the elevator car with the inductive braking device; causing the electromechanical brakes to lift while the inductive braking device is in the braking condition; determining a value associated with the inductive braking device in response to causing the electromechanical brakes to lift while the inductive braking device is actuated; and determining an operating condition of the inductive braking device based on the value.

摘要： Embodiments of the present disclosure are directed to a system for monitoring conditions of elevator braking assemblies. The system includes a processing device configured to receive an actual braking current data from the elevator braking assembly, determine a derivative, plot a derivative curve, determine a region of interest of the derivative curve that corresponds to an expected movement of the at least one mobile plate of the elevator braking assembly, determine whether a pair of inflection points occurred during the region of interest where one of the inflection points is a minimum point and the other is a maximum point, the maximum having a greater amplitude than the minimum point and occurring after the minimum point, and when the pair of inflection points does not occur during the region of interest, output an alert to the elevator controller to instruct the elevator controller to inhibit movement of the elevator cab.

摘要： A vertical magnetic frame system 142.a, and 142.b, installed in the elevator hoist way, holding on it the entire weight of the stationary traction rope rizes 120, 124, and 126, 128, for the prefered traction system described herein, and used it to move the self-climbing elevator 100, up, or down in the elevator shaft. Further, the preferred traction system is a novelty, allowing the elevator car 100 to move up by traction gears described in FIG. 2.a, FIG. 7.a, and FIG. 10, and to move down gravitationally described in FIG. 11, and in the process to collect more than 85 percent of gravitational velocity of the descending elevator car 100, turning it ito the electricity for the building using this system

摘要： An elevator system includes an elevator car moveable between a plurality of landings and a brake configured to stop the elevator car from moving within the elevator shaft. The system includes a safety controller and at least one safety device. The safety controller monitors for a change in status of the at least one safety device. Upon detection of a change to a new status, the safety controller evaluates whether the new status is a first status corresponding to an emergency situation or a second status corresponding to a non-critical change. The safety controller is further configured to apply the brake immediately to stop the elevator car when the new status is a first status or allow the elevator car to move to a landing when the new status is a second status.

摘要： An elevator counterweight assembly (11) includes a counterweight structure (38), at least one safety brake (12a, 12b) mounted on the counterweight structure (38), and a safety actuation mechanism (16) including a connection (17) for a suspension member (18). The safety actuation mechanism (16) is configured to move, relative to the counterweight structure (38), between a normal position, and a safety position. In the safety position the safety actuation mechanism (16) is arranged to actuate the at least one safety brake (12a, 12b) and thereby brake the counterweight structure (38). The counterweight assembly (11) also includes a mechanical actuator (22), configured, when actuated, to apply a force to the safety actuation mechanism (16) and thereby move the safety actuation mechanism (16) from the normal position to the safety position, e.g. for the purposes of a handover test.

摘要： An elevator disc brake assembly includes at least two separate operating disc brake units mounted substantially sequentially on the periphery of the brake disc of an elevator driving machinery where the brake disc and a traction sheave are rotated by a drive motor of the driving machinery. At least one of the disc brake units includes two or more separate brake plates to be pressed against the brake disc.

摘要： Disclosed is an elevator control system configured to control movement of an elevator car (12) along an elevator hoistway (26) between a starting position and a destination position (L2), the control system comprising a car holding position monitoring unit configured to monitor whether the elevator car (12) has moved upwards or downwards in the hoistway (26) during a holding period (68) where the car (12) was intended to remain stationary at the destination position (L2). The car holding position monitoring unit is configured to: Receive a first trigger signal (62) from a first car position reference system (40); upon receipt of the first trigger signal, receive signals from a further car position reference system to detect a first indicator (66) indicative of a travel distance (X2) between the position of the elevator car (12) in the hoistway (26) when receiving the first trigger signal (62) and the position of the elevator car (12) in the hoistway (26) when stopping at the destination position (L2); upon receipt of a further service call for the elevator car (12), receive further signals from the further car position reference system and receive a second trigger signal (70A) from the first car position reference system (40) to detect a second indicator (74A) indicative of a travel distance between the position of the elevator car (12) in the hoistway (26) at the end of the holding period (68) and the position of the elevator car (12) in the hoistway (26) when the elevator car (12) receives the second trigger signal (72A) from the first car position reference system (40); and detect whether the elevator car (12) has moved during the holding period (68) based on a comparison of the first indicator (66) and the second indicator (74A).

摘要： The invention relates to a method for operating an elevator system. The method comprises receiving a request to drive an elevator car to a destination and generating an elevator car motion profile to serve the received request. The elevator car motion profile comprises at least the following motion parameters of the elevator car: acceleration, maximum speed, and deceleration. At least one of the maximum speed of the elevator car and the deceleration of the elevator car in the generated elevator car motion profile is defined on the basis of the destination. The invention relates also to a processing unit and an elevator system configured to perform the method at least partly.

摘要： An elevator includes a drive, a car operatively connected to the drive to traverse along a travel path, at least one guide rail positioned along the travel path to guide the car, a safety brake arranged on the car to exert a braking force on the guide rail, and a safety system. The safety system includes a first safety control unit and a second safety control unit that monitor a safety condition of the elevator. The first safety control unit outputs a stop signal to the drive, in particular to a drive brake and/or to a frequency converter of the drive, and the second safety control unit outputs a trigger signal to the safety brake to bring the elevator into a proper safety condition when an impermissible safety condition of the elevator is detected.

摘要： A brake, in particular a safety brake, suitable for an elevator system having a guide rail and a caliper design. The brake includes two brake shoes and a first and second brake lever rotatably connected to each other via a swivel joint. A spring arrangement is configured to impinge on the first brake lever relative to the second brake lever in a first direction. An actuator arrangement is designed selectively to impinge on the first brake lever relative to the second brake lever in a second direction. The brake levers are configured to transfer the brake shoes between a first released operating state and a second active operating state as a function of the impingement by the spring arrangement and the actuator arrangement. The spring arrangement includes at least one plate spring assembly having in each case one or more plate springs.
