The causes and troubleshooting methods of brake failure in chain hoists

　　It is very dangerous to encounter brake failure during the use of a chain hoist. Once this situation occurs, the operation should be stopped immediately. The chain hoist should be inspected for components, the cause of the malfunction should be identified, and the problem should be resolved in a timely manner to ensure safe operation. What is the reason for the brake failure of the chain hoist

　　The brake failure of a chain hoist is caused by damage to the brake system components, which are composed of ratchets, claws, and friction plates. Any problem with any of these components can potentially lead to brake failure. If the ratchet breaks its teeth, it will be unable to engage with the pawl during the lifting process of the chain hoist, resulting in brake failure; When the pawl spring becomes loose, the pawl cannot grasp the pawl wheel in time, which can also lead to brake failure; When there is water or grease on the surface of the friction plate, the friction force on the surface of the friction plate decreases, and the braking ability also weakens accordingly, which can easily lead to brake failure. In addition, factors such as overloading the lifting of heavy objects, deformation of the outer shell due to compression, and thinning of the friction plate can also lead to brake failure of the chain hoist.

　　Handling method for brake failure of chain hoist:

　　The direct cause of brake failure is the failure of the ratchet or brake pads. Oil can cause the ratchet to malfunction, in which case the oil can be wiped off. If there are friction plates or other issues, it is recommended to have them repaired by professionals, and if necessary, damaged parts should be replaced. Of course, daily incorrect use is the deeper reason for the brake failure of the chain hoist. When using it, attention should be paid to the following situations.

　　1. It is necessary to operate in a standardized manner. Good operating standards are a necessary condition to ensure the service life and good condition of the chain hoist.

　　2. Do not overload the use of the chain hoist. Overloading can increase the friction between the pawl and the ratchet, causing the friction plate to become thinner, thereby affecting the braking effect.

　　3. Avoid excessive use of chain hoists. Hand chain hoists also require rest, as prolonged use can cause the springs on the pawls to loosen, affecting the braking effect.
