How does a hydraulic drum brake work?
The brake is mainly used in hoisting and transportation machinery, petroleum machinery and other occasions. The specific structure is simple, the use is relatively convenient, and the advantages of easy maintenance.
Take crane hydraulic block brake as an example, when the excitation coil is energized, it will attract the armature. Then, through the action of the push rod, the pulling force of the restraining springs of the two brake arms is moved sideways, so that the two brake blocks connected to each other will be released, and the machine can run freely. Cut off the electric two brake arms and clamp them inward. This one uses the power-off braking method.
The hydraulic drum brake manufacturer reminds you that after using the block brake for a period of time, you need to check it regularly. It mainly checks whether the various components can operate normally, whether the surface of the brake is defective, and whether the nut is tightened. Use it after ensuring that it has no failure .
