  • Publication number: 20200039789
    Abstract: An electronic safety actuator assembly for an elevator system includes a safety case vertically moveable relative to an elevator car. Also included is a safety brake disposed within the safety case. Further included is an electromagnet operatively coupleable to the elevator car. Yet further included is a link member operatively coupleable to the elevator car and to the safety brake. Also included is a magnet disposed between the electromagnet and the safety case, the magnet vertically moveable relative to the elevator car, the electromagnet switchable between an energized condition and an un-energized condition, one of the energized condition and the un-energized condition magnetically attracting the magnet to the electromagnet, the other of the energized condition and the un-energized condition magnetically repulsing the magnet away from the electromagnet, repulsion of the magnet moving the safety brake from a non-braking position to a braking position.

  • Publication number: 20170349406
    Abstract: An elevator system (10) is comprised of a car (22), and a shaft (46) operatively connected to the car and configured to rotate for movement of the car through the elevator system. A brake assembly (44) is comprised of a disk (56) connected to and configured to rotate along with the shaft. Movable plates (60, 62) are placed on respective opposite sides of the disk and configured to move axially toward and away from the disk. Electromagnets are configured to respectively move the movable plates away from the disk. Elastic elements (64, 66) are configured to respectively move the movable plates toward the disk. The disk is free to move axially, and is designed to stop the movement of the car by stopping the rotation of the shaft when the rotation of the disk is stopped by friction from contact of the movable plates with the disk when the elastic elements move the movable plates toward the disk.

  • Patent number: 9791009
    Abstract: A method for monitoring brake torque of an elevator having a motor is provided. The method may engage an elevator brake for a predefined duration, determine a displacement of an output shaft of the motor during the predefined duration, and generate an alert if the displacement exceeds a predefined threshold.

  • Patent number: 9637349
    Abstract: An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.

  • Patent number: 8746413
    Abstract: A control arrangement (100) for an elevator brake, comprises a control circuit (110) adapted to generate, according to a demand for releasing a first braking member of the elevator brake, a first actuating signal and to generate, according to a demand for releasing a second braking member of the elevator brake, a second actuating signal; a first terminal (112) for outputting the first actuating signal to a first electromagnetic actuating means (26) of the elevator brake, a second terminal for outputting the second actuating signal to a second electromagnetic actuating means (30) of the elevator brake; the control arrangement (100) being adapted to allow at least the following modes of operation: A) a normal operation mode in which the first and the second actuating signals are supplied synchronously to the first and second electromagnetic actuation means (26, 30), respectively, and B) a single braking member test operation mode, in which one of the first and second actuating signals is supplied to the respect

  • Publication number: 20130081905
    Abstract: An elevator brake component used in a friction brake of an elevator includes a metal plate that is frictionally engaged with another brake component when the elevator brake is engaged. The plate includes a non-stick finish on the metal plate on a surface of the plate that is frictionally engaged when the elevator brake is engaged by the other brake component.

  • Publication number: 20100154527
    Abstract: A brake (42) is tested in an elevator system (10) including a car (12) and a counterweight (14) connected to the car (12) by a rope (16). The car (12) is positioned at a reference position in the hoistway (HW) adjacent to a hoistway limit switch (23), and the brake (42) is engaged to hold the car (12) at the reference position. The rotating member (46) is then driven to provide a testing force on the brake (42) that simulates a load in the elevator car (12) of at least a maximum rated load for the car (12). The brake test is terminated if the hoistway limit switch (23) is actuated.
