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.

This awe-inspiring collection covers the largest, top-of-the-line mining equipment in each of the manufacturer's five major classes; haulers, wheel loaders, hydraulic shovels, graders, and bulldozers. Design, development, and production histories are accompanied by the stories of these gargantuan machines in service, as well as details of the Herculean efforts required for their assembly. Incredible modern color photography from both the author and the Caterpillar archives provide shots of the equipment in action and production, not to mention detail shots to help explain their working componentry.
