The Escalator Brake include: working brakes, additional brakes and auxiliary brakes. The operating brakes are normally mounted on the high speed shaft of the motor and should be such that the escalator is stopped at a nearly constant speed during the stop operation , And can stay stopped. Work brakes in the course of action should be no intention of delay. The working Brake shall be of a normally closed mechanical-electrical brake which shall be controlled by at least two sets of independent electrical devices which must be produced by means of a guide compression spring or the like. Actuators for escalators usually use block brakes, belt brakes and disc brakes. The brake force of the block brake (brake shoe) is radial and the brake blocks used are in pairs so that the brake pads are balanced with each other and the brake axle is not subjected to bending loads. The components of the block brake are the brake wheel, the brake pad and the high friction coefficient of the pad, the brake arm and the release riveted thereon. When the escalator is stopped, the electromagnetic coil is de-energized, the brake shoe is under the action of the brake spring, hold the brake drum, the escalator stops. Run on the escalator at the same time there is a micro-switch to verify the brake is fully open, in order to protect the brake. This brake is simple to manufacture, easy to manufacture and install.
