At the end of spring withstood brake activities around the surface of activities brake, and the brakes could be sliding along the axis of the motors, not because of brake pads wear affect braking force. 4. a manual switch devices power-cut or emergency, the light drop pull rod, roll door dropped to required location of door smoothly and automatically.
