Abstract

The invention relates to a process and a device for load-adaptive overload monitoring. According to the invention, a load integral (IPü) and an overload compensation (APü) are formed initially and an overload result (EPü) is then formed from the difference between the overload compensation (APü) and the overload integral (IPü), the overload result (EPü) indicating whether the consequences of an overload (Pü) are reduced and the load integral (IPü) indicating how much overload reserve is still available. A renewed overload (Pü) can thus be permitted much earlier if the overload consequences are reduced, or a plurality of overloads can be permitted within an overload time interval. <IMAGE>
