  • Patent number: 7735610
    Abstract: The invention relates to a method for controlling a braking unit of a rope transport installation and braking unit. The command signals of a first brake are modulated, until the installation is stopped, by a first modulation circuit integrated in the control unit to automatically regulate the running speed of the rope according to a first predetermined deceleration setpoint curve activated by a braking order. The command signals of a second brake are simultaneously modulated by a second modulation circuit integrated in the control unit to automatically regulate the running speed of the rope according to a second predetermined deceleration setpoint curve activated by the braking order, the instantaneous value of the second setpoint curve being at all times greater than the value of the first setpoint curve.

  • Publication number: 20080029348
    Abstract: The invention relates to a method for controlling a braking unit of a rope transport installation. The command signals of a first braking means are modulated, until the installation is stopped, by means of a first modulation circuit integrated in the control unit to automatically regulate the running speed of the rope according to a first predetermined deceleration setpoint curve activated by said braking order. The command signals of a second braking means are simultaneously modulated by means of a second modulation circuit integrated in the control unit to automatically regulate the running speed of the rope according to a second predetermined deceleration setpoint curve activated by said braking order, the instantaneous value of the second setpoint curve being at all times greater than the value of the first setpoint curve. The invention also relates to a braking unit of a rope transport installation enabling the method to be applied.
