Models of construction machinery are the crowning glory of commercial vehicle modelling. Here not only the quality of the construction must be right, the models must also be designed to cope with sometimes heavy loads during operation. All the functions that excavators, caterpillars, wheel loaders and dumper in one model is another art in this field. But Kits and ready-made models are expensive and sometimes reach prices in the five-digit euro range. The alternative is do-it-yourself construction, which can also be achieved with modest means, as the author Walter Penka shows in this book. He has successfully built various types of construction and shows here his design and construction techniques. The examples of successfully functioning machines shown here enable those who want to build replicas to turn their ideas into reality. The dream of a functional construction machine model can thus become a reality.
