In order to extend the service life of explosion-proof chain cranes, the following are some key maintenance measures:

1、 Daily inspection and maintenance

Appearance inspection:

Regularly inspect the appearance of the crane, including components such as chains, hooks, brakes, controllers, etc., to ensure that there is no obvious damage or deformation.

Check if the fasteners of the crane are loose, and tighten them promptly if they are loose.

Functional testing:

Regularly test the various functions of the crane, such as lifting, lowering, braking, etc., to ensure normal functionality.

Pay special attention to the performance of the brake system to ensure that it can brake quickly and reliably in emergency situations.

Cleaning and lubrication:

Regularly clean the crane, remove surface dirt and oil stains, and keep it clean.

Lubricate the moving parts of the crane, such as chains, bearings, etc., to reduce friction and wear.

2、 Professional maintenance and upkeep

Chain maintenance:

Regularly check the wear of the chain, and replace it promptly if there is severe wear or breakage.

The chain should be kept in good lubrication condition to reduce wear and extend its service life.

Hook inspection:

The hook is an important component of the crane and should be regularly inspected for wear, deformation, or cracking.

If any safety hazards are found in the hook, it should be replaced immediately.

Electrical system inspection:

Regularly inspect the electrical system of the crane, including cables, motors, controllers, and other components.

Ensure reliable connection and good insulation of the electrical system to avoid safety accidents caused by electrical faults.

Brake maintenance:

The brake is an important safety component of the crane, and its braking clearance and braking torque should be checked and adjusted regularly.

If the performance of the brake is found to have decreased or there is a malfunction, it should be repaired or replaced in a timely manner.

3、 Long term storage and maintenance

Storage environment:

If the crane needs to be stored for a long time, a dry and well ventilated environment should be selected to avoid moisture and corrosion.

When storing, the crane should be placed on a stable ground to avoid tilting or shaking.

Regular activation:

Even if the crane is in long-term storage, it should be started and operated regularly for a period of time to maintain the normal working condition of its various components.

Comprehensive inspection:

Before reusing the crane after long-term storage, a comprehensive inspection should be conducted to ensure that its various functions are normal, safe, and reliable.

4、 Training and Awareness Enhancement

Operator training:

Regularly provide training on safe operation and maintenance to operators to enhance their safety awareness and operational skills.

Security awareness enhancement:

By promoting safety awareness and analyzing case studies, we aim to increase the importance that operators place on the safe use and maintenance of cranes.
