Safety brake control apparatus for emergency stop of escalator

PURPOSE: A device for controlling an emergency safety brake of an escalator is provided to stop the operation of the escalator by stopping the rotation axis of the escalator in an emergency situation. CONSTITUTION: A main control panel(20) applies power to a driving motor of an escalator. A counter rotation sensor(31) senses the rotation direction of the rotation axis of the escalator. An overspeed sensor(32) senses the rotation speed of the rotation axis of the escalator. An emergency stop safety brake(40) mechanically blocks the rotation of the rotation axis of the escalator. A controller(10) controls the emergency stop safety brake or main control panel according to the signal of the counter rotation sensor and the overspeed sensor.
