As an important industrial equipment, crane plays a decisive role in industrial production. However, long-term use and irregular maintenance can easily lead to some failures and problems in the crane. In order to ensure the normal operation and safety of the crane, crane maintenance work is particularly important. In this issue, we will introduce the maintenance content of cranes in detail from two aspects: daily maintenance and regular maintenance.

Routine maintenance mainly includes the following aspects:

1. Cleaning and maintenance: Clean the crane regularly, including removing dust and debris on the surface of the fuselage to keep the crane tidy.
2. Lubrication maintenance: Check and refuel the lubrication parts of the crane regularly to ensure that each component is in good lubrication condition.
3. Electrical system inspection: Regularly inspect the crane’s electrical system, including cables, power supply and control systems, to ensure the normal operation of electrical equipment.
4. Safety device inspection: Regularly check the safety devices of the crane, such as limiters, heavy-load protectors and circuit breakers, etc., to ensure the reliability of the safety devices.
5. Inspection of mechanical components: Regularly inspect the mechanical components of the crane, such as gears, bearings and transmission devices, to ensure the normal operation of the mechanical components.

Regular maintenance mainly includes the following aspects:

1. Cleaning and maintenance: Clean the crane regularly, including removing dust and debris from the surface of the fuselage, and keep the crane tidy.
2. Lubrication and maintenance: Regularly check the lubricating parts of the crane and add oil to ensure that each part is in good lubrication condition.
3. Electrical system inspection: Regularly inspect the crane’s electrical system, including cables, power supply and control systems, to ensure the normal operation of the electrical equipment.
4. Inspection of safety devices: Regularly check the safety devices of the crane, such as limiters, heavy-load protectors and circuit breakers, to ensure the reliability of the safety devices.
5. Inspection of mechanical components: Regularly inspect the mechanical components of the crane, such as gears, bearings and transmission devices, to ensure the normal operation of the mechanical components.
