In the maintenance of chain hoists, replacing the brakes is an important step that directly affects the safety and reliability of the crane. The following are the general steps and precautions for replacing the brake of a chain hoist:

1、 Preparation work

Shutdown and power outage: Firstly, ensure that the chain hoist has completely stopped and cut off the power supply to prevent accidental start-up during the replacement process.

Prepare tools: Prepare the necessary tools such as wrenches, screwdrivers, jacks (if needed to support heavy objects), etc.

Check the brake system: Before disassembly, carefully inspect all components of the brake system, including brake pads, brake discs, springs, adjustment devices, etc., to determine the specific parts that need to be replaced.

2、 Dismantle the old brake

Loosen the fixing screws: Use a wrench or screwdriver to loosen the screws that secure the brake components. Be careful to maintain balance when loosening screws to avoid damaging other components.

Remove brake components: After the screws are completely loosened, carefully remove the brake components from the crane. If the brake components are connected or clamped to other parts of the crane, it may be necessary to use appropriate tools or methods to separate them.

3、 Install new brakes

Clean the installation surface: Before installing a new brake, wipe the installation surface with a cleaning agent or cloth to ensure that there are no dust, oil stains, or other impurities.

Install brake components: Install the new brake components onto the crane in the correct order and position. During the installation process, pay attention to the direction and position of the brake components to ensure that they can work properly.

Tighten the fixing screws: Use a wrench or screwdriver to tighten the screws that secure the brake components. When tightening screws, follow the prescribed torque to ensure that the brake components are firm and reliable.

4、 Adjustment and Testing

Adjust brake clearance: Adjust the clearance between brake components according to the crane's user manual or relevant standards. The size of the brake clearance will affect the braking effect and the performance of the crane.

Test brake performance: After installation and adjustment, conduct a brake performance test. The sensitivity and reliability of brakes can be tested by simulating the actual working scenario of a crane. If any problems or abnormal situations are found, they should be adjusted or repaired in a timely manner.

5、 Precautions

Safety first: Throughout the entire replacement process, safety must always be given top priority. Ensure that the crane is in a stopped state and cut off the power before proceeding with the operation.

Follow the specifications: Operate and install according to the instructions and relevant standards of the crane. Do not arbitrarily change or omit any steps.

Professional maintenance: If you do not have enough experience and skills to replace brake components, it is recommended to seek the help of professional maintenance personnel.
