摘要:
Upon detection of a trapped passenger in an elevator car, a resident monitoring device initiates communication between the car and a telephone in the building and between the car and a remote monitoring center. Upon detection of the first responsive telephonic communication from either the remote monitoring center or the telephone in the building, voice communication is established therebetween. Upon detection of a second responsive telephonic communication from the second location to respond, voice communication is established between the car and the second location as well so that simultaneous communication may be conducted between the car, the remote monitoring center, and the telephone in the building. A building telephone has a keypad which can be used to select another car for voice communication with a trapped passenger by pressing a selected key. A telephone ring voltage source is provided for alerting building personnel of a trapped passenger. A dual-tone, multi-frequency decoder is provided for determining which keypad button is depressed.

Die im Sicherheitskreis von mindestens einem Fahrschütz einer Aufzugsteuerung liegende Sicherheitskontakte insbesondere Tür- und Riegelkontakte (S1 bis S4), die in Serie mit insbesondere zwei parallel zueinander geschalteten Fahrschützen (RA, RS) zwischen einen ersten Speisespannungsanschluß (A) und einen zweiten Speisespannungsanschluß (B) geschaltet sind werden überwacht. Den einzelnen Sicherheitskontakten (S1 bis S4) sind Kontrollschaltungen (K1 bis K4) zugeordnet, die so dimensioniert sind, daß Parallelzweige zur Sicherhe i tsstrecke entstehen, über die auch im ungünstigsten Fall nur ein Strom -fließen kann, bei dem die angeschlossenen Schütze (RA, RS) mit Sicherheit abfallen und mit Sicherheit nicht anziehen.
摘要:
A pair of elevator cars (10, 11) traveling in the same hoistway have their positions sensed (20-23, 29-32) to provide for each a position signal (35, 37) from which velocity signals (64, 65) are derived; lookup tables (66, 61) of safe stopping distance (B, S) for braking and safeties are formed as a function of all possible combinations of velocity (V(U), V(L)) of said cars. Comparison of safe stopping distances for contemporaneous velocities of said cars with actual distance between said cars provides signals (85, 98, 99) to drop the brakes (49, 50) of one or more of the cars, and provides signals (82) to engage the safeties (18, 18a, 19, 19a) of all cars if the cars become closer or if acceleration detectors (117, 118) determine a car to be in freefall.
摘要:
The invention relates to a method for monitoring condition of a belt-shaped rope (1) of an elevator, which rope (1) is connected with one or more elevator units (2, 3) of an elevator, the method comprising monitoring lateral positions of successive rope locations which rope locations pass during use of the elevator via a monitoring zone (4) located in proximity of a crowned rope wheel (5) around which the belt-shaped rope (1) is arranged to turn; gathering lateral position data (D) of the belt-shaped rope (1), which lateral position data indicates lateral positions of several successive rope locations of the rope (1) at the monitoring zone (4); and analyzing the lateral position data; and detecting characteristics in the lateral position data indicating damaged rope (1); and triggering one or more predefined actions if characteristics indicating damaged rope are detected. The invention also relates to an arrangement (A) and an elevator, which implement the method.
摘要:
In an elevator apparatus, an output portion electrically detects an abnormality in an elevator, and outputs an actuation signal upon detecting the abnormality. The actuation signal from the output portion is input to an actuator portion. Mechanical detection means mechanically detects an abnormality in the elevator, and mechanically transmits a control force to a braking member. When the actuation signal is input to the actuator portion, the braking member is caused to perform braking operation. Further, even in the case where the actuation signal has not been input to the actuator portion, the braking member is caused to perform braking operation through the control force from the mechanical detection means when the mechanical detection means detects an abnormality.
摘要:
A guide device is operable to be connected to a hoisted object to aid in guiding the hoisted object relative to a guide member. The guide device includes a shoe, a gib, and a wear detector. The shoe is operable to be connected to the hoisted object. The gib is operable to be connected to the shoe. The gib is operable to contact the guide member when the hoisted object is moved relative to the guide member. The gib is operable to experience an amount of wear as a result of the contact between the gib and the guide member. The wear detector is disposed relative to the gib and the guide member. The wear detector is operable to detect when the amount of wear experienced by the gib reaches a predetermined threshold.

The object of the present invention is a testing method and installation for testing remote alarm systems in elevators which allow performing a quick, efficient and thorough testing of alarm systems (210) of elevators (200), said test being completely independent of the model and/or manufacturer of the alarm system (210) in terms of testing, providing the method and the installation described herein with a universal character, valid for any elevator (200) equipped with an alarm system (210), and with the possibility of carrying out said test without requiring a human operator.
摘要:
An elevator apparatus includes: door opening/closing detection means (2, 3); car-position detection means (1) for detecting whether or not the car is present within a preset allowable range of car running under the door-open state; means (4) for preventing the car from starting under the door-open state, for determining a state in which the car starts under the door-open state to stop the car when at least one of the car door and the landing door is in the door-open state and the car position is out of the allowable range of car running under the door-open state, based on the results of detection by the door opening/closing detection means (2, 3) and the car-position detection means (1); and virtual-signal generation means (6, 7) for generating a virtual signal for virtually creating the state in which the car starts under the door-open state when being operated in a test mode, in which, when the means for preventing the car from starting under the door-open state determines the state in which the car starts under the door-open state based on the results of detection by the door opening/closing detection means (2, 3) and the car-position detection means (1) and in preferential consideration of the virtual signal generated by the virtual-signal generation means (6, 7) in the test mode, the means (4) for preventing the car from starting under the door-open stops a car (10).
