Abstract: A set of elevators includes a plurality of elevators without counterweight, a power supply, and a common control system. The plurality of elevators has a common connection to the power supply. The common control system includes one or more instructions to prevent or delay dispatch of an elevator car stopped at a floor if, at that instant, within a set period of time, or at that instant and within the set period of time, power consumed from an associated electrical network by the set of elevators or fed into the associated electrical network by the set of elevators together exceeds a set value. A method for controlling a set of elevators includes determining whether power consumed together exceeds a set value, and when the power consumed exceeds the set value, then departure of a next elevator car to be dispatched is prevented or delayed.

Abstract: A vibration damping system for an elevator is provided with a damping device (5) that is provided between a cab (1) and a car frame (2) for supporting the cab (1) and whose damping coefficient can be changed. A speed detector detects the traveling speed of a reference elevator car, and a calculation unit (15) receiving the traveling speed detected by the speed detector calculates a control signal for the damping device (5), and outputs the control signal to the damping device. The calculation unit (15) controls the damping device (5) in such a way that, in the case where the traveling speed exceeds a predetermined value, the damping coefficient of the damping device (5) is larger than that in the case where the traveling speed is the same as or smaller than the predetermined value.

Abstract: The present invention pertains to a method for optimal routing of the elevators in an elevator system in a situation where the supply power received by the system is limited e.g. due to emergency power operation. In the invention, routes are optimized by using a cost function to which has been added a term containing the summed instantaneous power consumed. Power consumption is monitored in real time, and the elevators need a start permission from the control system. A route alternative that exceeds the power limit is penalized in the cost function by a so-called penal term. With the elevator routing obtained as a result, the instantaneous power consumed by the system remains continuously below the set power limit. Some call can thus be postponed to be served later. By the method of the invention, the number of elevators serving passengers in an emergency power situation can be varied dynamically.

Abstract: An elevator drive has a brake device with compression springs to actuate brake levers, and brake linings on a brake drum creating a braking force. A sensor is provided to detect the movement of a brake magnet armature tappet. A bracket is attached to the brake magnet tappet on one end and a distance piece carrying the sensor housing is arranged on the other end. A restoring lug is attached to the existing mechanical indicator. A monitor evaluates the sensor signal and turns off the elevator drive in the event of dangerous operational states via a safety circuit. The system allows the state of the brake device to be monitored. The more the brake linings wear off due to abrasion, the smaller the distance between the armature and the brake magnet housing. If the armature is in contact with the brake magnet housing, the braking ability of the brake linings is completely void.

Abstract: Since the elevator type is varied, a set value used for judging car oscillation must be set for each elevator, which requires much time and labor. Also, if the criteria of all elevators are represented by one set value to eliminate the time and labor required for the setting, variations in detection occur. A car oscillation detecting device includes a means in which a set value, which is used as a criterion for judging car oscillation, is stored in advance as a table or a relational expression in which an elevator specification is used as a parameter, and the set value is selected automatically by using the information of the elevator specification, by which the time and the labor for setting are eliminated. Further, since the set value is a value suitable for that elevator, variations in detection can be restrained, and hence the reliability is high.

Abstract: An earthquake control operating system for an elevator is provided so that the elevator can operate free of the influence of earthquakes. Data concerning zones without resonance between the intrinsic vibration frequency of the ropes of the elevator and the intrinsic vibration frequency of the building, and data corresponding to the speed at which vibrations of ropes of the elevator are in a safe range during a long-period seismic wave are stored in a database. When an emergency earthquake report is received by an emergency earthquake information receiver, the elevator car is driven to a floor free of resonance at the speed stored in database. Then, when it is judged that the long-period seismic wave has been sufficiently attenuated on the basis of a detection signal of a long-period vibration sensor, the operation of the elevator is restored.

The brake device has a brake control portion for controlling a braking force generated at a time of emergency braking to adjust a deceleration of the car, and a timer circuit for invalidating the control of the braking force performed by the brake control portion after a lapse of a predetermined time from a moment when an emergency braking command is generated.

Abstract: A car door is displaced with respect to a landing door between an engagement position at which the car door is engaged with the landing door and an open-away position located on a door-closing side with respect to the engagement position. While remaining engaged with the car door, the landing door is moved to open/close a landing doorway. When the landing doorway is fully closed by the landing door, a locking device performs an operation corresponding to the position of the car door with respect to the landing door to lock/unlock the landing door. A door control device has an engagement completion time calculating portion, a speed pattern generating portion, and a speed control portion. The engagement completion time calculating portion predicts an engagement completion time to a moment when the car door reaches the engagement position during a door-opening operation, based on information from an unlock detecting device for detecting whether or not the landing door has been unlocked.

In one example, a signaling device (26) includes a plurality of switches (28) that can be activated to provide a signal indicating a desired or intended destination. The signal also provides an indication of the individual from whom the signal is received.

In one example, the system maintains information regarding expected locations of individuals providing such signals to facilitate providing assistance to them for exiting a building, for example.
