GY and GY20 - double circuit brake system

The service brake is equipped with an electro-mechanical system. During operation, it remains in open position, due to the continuous flow. In a failure of the power supply to the brake system or the control circuit, the braking system under spring pressure drops automatically and brings the escalator in the emergency stop position. The operating state of the brake is monitored by a sensor and outputs it to the control unit permanently.

From a head of 6m a double circuit braking system is used to communicate the 2 control circuits and sensors autonomously and independently with the control.
