Problems solved by technology

[0002] For production cranes, electric brakes are currently used for the braking of the drum, and when the drum needs to be stopped, the brake shoes are used to stop the drum from working. There are certain disadvantages in the existing brake, mainly in the following aspects: The brake needs to clamp the brake shoes under the action of external force to stop the drum normally. When the external force drive device is in the power-off state, the lower side cannot normally control the start and stop of the drum. In this way, when the drum lifts heavy objects, if the brake suddenly loses power , it is difficult to ensure that heavy objects will not fall, and may even cause accidents. In addition, the brakes set on the outer wall of the drum are not easy to adjust, so that the clamping state of the brakes is uncontrollable
