What is the crane working level

Many friends don't know what the crane working level refers to. I tells you: the crane working level is a parameter indicating the degree of heavy lifting of the crane, that is, the parameter indicating the degree of heavy lifting and full load of the crane in terms of time.

It should be pointed out that the working level of the crane and the lifting capacity of the crane are two different concepts. Lifting weight refers to the quality of the material being lifted at one time, and the working level is the comprehensive working characteristic parameter of the crane. If the lifting weight is large, the working level may not be high; if the lifting weight is small, the working level may not be low. Even if the cranes of the same type have the same lifting weight, as long as the working levels are different, the safety factors of the parts are not the same.

If you only look at the lifting tonnage and ignore the work level, and use low-level cranes frequently and at full load, it will accelerate the scrapping of vulnerable parts, cause frequent failures, and even cause accidents.

In addition, it should be noted that the working level of cranes and metal structures is different from the working level of institutions. For the same crane, due to the inconsistency of the load and the unequal time of each working mechanism, even for the same crane, the working level of different mechanisms is often inconsistent with the working level of the crane. This is in the parts of different mechanisms. Pay special attention when scrapping and updating.

Job level classification:

• Light (A1-A3): Rarely lift rated load, generally lift light load, mostly used for installation and maintenance of equipment in power stations or other workplaces, or workshops and warehouses where work is not commonly used.
• Intermediate (A4-A5): Sometimes the rated load is lifted, and the medium load is generally lifted. It is used in heavy-duty workshops and garages, such as general machining and general assembly workshops.
• Heavy (A6-A7): Normally, the rated load is lifted, and heavier loads are generally lifted. It is used in workshops and warehouses with heavy work, such as frequent lifting and carrying heavy items for a long time and metallurgical workshops.
