The usage methods and requirements of the bridge crane hook set are as follows:

Usage methods:

1. When lifting heavy objects, make sure that the heavy objects are located in the middle of the hook seat to maintain balance.

2. When lifting, keep it stable to avoid excessive impact and loads to prevent damage to the hook or crane.

3. Regularly check the surface of the hook to ensure it is smooth and free of cracks, sharp corners, burrs and cracks.

Requirements:

1. The hook should be made of low-carbon steel or low-carbon alloy steel, and its tensile strength shall not be lower than the specified tensile strength value of the steel.

2. The surface of the hook should be smooth and there should be no defects such as cracks, acute angles, burrs or overburn.

3. The hook must be equipped with a safety device to prevent the hanging object from falling off unexpectedly to improve safety.

4. The size of the hook should meet the design requirements, and its dimensional deviation should comply with relevant standards.

5. The hook should be tested before use. The new hook should be load-tested at 2.5 times the rated load, and the load time is 10 minutes. After unloading, check for cracks and deformation, and must be flawed and can only be used after passing the inspection.

6. The cross head, cable cavity, rod threads, shaft diameter and other components of the hook are places where stress is concentrated and cracks are prone to occur. Therefore, inspections should be carried out frequently before and during use to ensure that there are no defects such as cracks.

7. The accessories of the hook should be firmly connected to the hook body and be able to withstand corresponding loads.

In addition, daily inspections are required for the inspection of the hook and regular inspections are also required to ensure the safety and reliability of the hook. If abnormal conditions are found in the hook, the instrument should be used for regular measurements in time to ensure the safe use of the bridge crane.
