The high-speed brake of the bucket elevator does not participate in the starting, running, and stopping process of the elevator, but plays a role in stopping the machine's speed during safe braking of the bucket elevator.
The homework brake is a brake used to improve the operation brake and safety brake of the machine. When the lifting machine is operating normally, the operation brake is released, and the speed control brake is closed to complete the operation of lifting or releasing goods.
When speed regulation is required, control these two brakes to complete the acceleration and deceleration of the hoist. Once an emergency situation or power outage occurs, the power is cut off through the foot switch, the solenoid valve loses power, and the brake shoes will cause the brake wheel system to tighten, then reach the requirement of safe braking. Generally, when the engine is started, the wear of both the high-speed brake and the service brake is reduced and within the safe range. When the speed control brake is used for a long period of time, the conflict loss of the brake is relatively large, and the brake shoes of the brake show a phenomenon of heating up and turning red.
