Patent ID: 7735610

Claim:
Method for controlling a braking unit of a rope transport installation, the braking unit comprising a speed sensor delivering an acquisition signal representative of the running speed of the rope and transmitting said acquisition signal to a control unit that is able, after receipt of an external braking order, to transmit first command signals and second command signals respectively to distinct first and second braking means individually able to generate a braking force of the rope according to the corresponding command signals, wherein the command signals of the braking means are modulated by means of a first modulation circuit integrated in the control unit to automatically regulate the speed of the rope according to a first predetermined deceleration setpoint curve activated by said braking order, wherein the command signals of the first braking means are modulated until the rope is stopped and wherein the command signals of the 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 curve being at all times greater than the value of the first curve.
