The lifting capacity of electric overhead crane refers to the maximum of the lifting weight once time, and the working level is the comprehensive working characteristic parameter of electric overhead 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 overhead cranes with the same weight, as long as the working level is different, the safety system of each component of electric overhead crane may be different, and the corresponding specifications, models and sizes are also different.
If only pay attention to lifting weight and ignore the working level, use the electric overhead crane with light working level for frequent and full load, it will accelerate the scrapping of the electric overhead crane and various parts, causing frequent failures and even accidents, affecting safety.
Therefore, must calculate the work level before purchasing the electric overhead crane.
