lifting capacity and the working duty of crane

- Jul 11, 2018-

The lifting capacity of the crane and the working duty of the crane are two completely different concepts.

   The lifting capacity of the crane refers to the maximum mass of the lifting weight at one time, and the working level is the comprehensive working characteristic parameter of the crane. There is no direct and inevitable connection between the two, the weight is large, the work level is not necessarily high, the work level is high, and the lifting weight is not necessarily large. Even for two cranes with the same weight, as long as the working level is different, the safety system of each component of the crane may be different, and the corresponding specifications, models and sizes are also different. If you look at the lifting weight of the crane and ignore the working level, and use the crane with light working level for frequent and full load, it will accelerate the scrapping of the crane and various parts, causing frequent failures and even accidents, affecting safety. .

    Therefore, the majority of crane users must calculate the level of their future use to select the crane's working duty before purchasing the crane.
