Reasons for Brake Failure and Troubleshooting Methods

Reason for brake failure

The brake failure of a running chain crane may be caused by various reasons, mainly including the following aspects:

Impurities or wear:

If there are impurities inside the brake, it will affect the braking performance and even lead to brake failure.

Severe wear of brake components, such as brake shoes and brake pads, can reduce the braking effect and prevent the crane from effectively stopping.

Improper lubrication:

Brakes require proper lubrication to ensure their normal operation, but excessive or insufficient lubrication can lead to brake failure.

If lubricating oil or grease seeps into the interior of the brake, it will contaminate the brake surface, reduce the friction coefficient, and thus affect the braking effect.

Improper operation:

If the operator operates the crane improperly, such as lifting or lowering the brake before fully releasing it, it may cause damage or failure of the brake.

Long term use of the brake without proper rest and cooling may also lead to overheating of the brake, reducing its braking performance.

Design and manufacturing defects:

The design and manufacturing quality of the brake directly affect its braking effect. If the design is unreasonable or there are defects in the manufacturing process, it may cause the brake to fail during use.

Insufficient maintenance:

Regular inspection and maintenance of the brake is key to ensuring its normal operation. If maintenance is insufficient, such as failure to replace worn parts in a timely manner, failure to clean internal impurities, etc., it may lead to brake failure.

Troubleshooting methods

The following troubleshooting methods can be adopted to address the issue of brake failure in operational chain hoists:

Inspection and cleaning:

Regularly inspect the brake, clean the internal impurities and oil stains, and ensure that the brake surface is clean and smooth.

Check the wear of the brake, and if the wear is severe, replace the worn parts in a timely manner.

Adjust lubrication:

According to the instruction manual of the brake, adjust the type and amount of lubricating oil to ensure that the brake receives appropriate lubrication.

Avoid lubricating oil or grease from seeping into the interior of the brake and contaminating the brake surface.

Standardized operation:

Train the operators to ensure they are familiar with the operating procedures of the crane and the use of the brakes.

Avoid lifting or lowering the brake without fully releasing it to reduce damage to the brake.

Strengthen maintenance:

Develop a regular maintenance plan and conduct regular inspections and maintenance on the brakes.

Timely replace worn parts to ensure the normal operation of the brake.

Inspect and repair the electrical system:

If the brake failure is related to the electrical system, the connection of the electrical circuit should be checked to ensure that the electrical system is functioning properly.

If electrical components are damaged, they should be replaced in a timely manner.
