Under the term heavy engineering, imagine heavy vehicles specially designed for civil engineering, surface and deep mining works. Previously, these works were performed by draft animals or simple machines. However, since the beginning of the 20th century, this field of engineering has changed significantly. Today, it is about sophisticated, automated and powerful devices. We have in mind, for example, wheeled excavators, bulldozers, cranes, excavators and loaders. In addition to such machines, ordinary vehicles only look like children's toys.
