Just like the B1-B4 classification in DIN 15018, the S classes also take into account the frequency of use per unit time (number of load changes) and the proportion of loading operations with light, medium or heavy loads (voltage spectrum) of the crane.just like the B1-B4 classification in DIN 15018, the S classes also take into account the frequency of use per unit time (number of load changes) and the proportion of loading operations with light, medium or heavy loads (voltage spectrum) of the crane.
