Hydraulic Excavators are subjected to tip-over situations with potential hazardous outcome. The given work analyses the state of the art of tip-over protection methods, including the current mandatory overload protection system. Using methods derived from the area of robotics, an algorithm for use as an assistance system was developed to predict and actively prevent dangerous tip-over situations. The developed method was evaluated in multi-body simulation models and in physical field tests.
