The maintenance of bridge cranes is generally divided into primary maintenance and secondary maintenance. So what is the primary maintenance and secondary maintenance of bridge cranes?

The first-level maintenance of bridge cranes

The first-level maintenance refers to the maintenance performed by the bridge crane during operation for one month. Operators are the mainstay, and maintenance workers cooperate. The main contents of the primary maintenance are as follows:

1.  Conduct a comprehensive inspection of the mechanical transmission part, electrical equipment and metal structure of the entire bridge crane.
2.  All lubrication points are cleaned and lubricated according to their respective lubrication cycles.
3.  Disassembly, replacement or repair of individual parts.
4.  Repair or replacement of certain electrical components.
5.  For mechanical and electrical parts with a tendency to be damaged, the bridge crane shall make technical preparations as a predictable repair content, so that it can be repaired in the next cycle.

Second-level maintenance of bridge cranes

Second-level maintenance refers to the second-level maintenance that the equipment runs for 3 months, 6 months, and 1 year. Maintenance workers are the main part and the operators participate.

1.  Including all the contents of primary maintenance.
2.  Disassemble, inspect, clean, repair or replace and lubricate the machinery and electrical parts of the bridge crane with frequent work and heavy load.
3.  According to the plan, replace the mechanical and electrical components that have been technically prepared in the previous period.
4.  Conduct a comprehensive inspection of the electrical circuit of the bridge crane, and replace part of the aging wiring and damaged electrical components.

Periodic maintenance of bridge cranes is to ensure that the crane does not have any problems during normal operation, so it is very necessary to carry out.
