  • Method for operating elevators to test brakes
    Patent number: 9061864
    Abstract: A method for operating an elevator having a car driven by a motor and at least one brake to stop the car, the method including closing a brake, increasing a torque of the motor until the car moves, and registering a value indicative of the motor torque at which the car moves.
    Type: Grant

    Date of Patent: June 23, 2015
    Assignee: Inventio AG
    Inventors: Erich Spirgi, Daniel Bossard, Danilo Peric, Enrique Almada, Urs Ammon, Urs Polin, André Peter, Thomas Eilinger
  • Method for releasing a load-carrying apparatus or a compensating weight of an elevator from a stopping position
    Patent number: 8668055
    Abstract: An elevator load receiving apparatus or a compensating weight connected thereto by a suspension device is released from a safety device in a stopping position after downward travel, the load receiving apparatus and the compensating weight being moved by a drive unit including a reversible electric motor and a traction sheave engaging the suspension device. Many safety devices, after stopping must be moved counter to the travelling direction of the load receiving apparatus before stopping in order to release (moved upwards in the case of stopping after downward travel). The safety device is easily released by activating the drive unit for a time (tmax1) or a certain distance (smax) with a predetermined torque (Mmax) counter to the direction of release and subsequently activated as abruptly as possible with the predetermined torque in the direction of release. This method can be used to release the compensating weight from its stopped position.
