When it comes to the construction machine simulator, the realistic simulations of the machines themselves, as well as the bulk material in particular, take center stage. Through this simulator trainees have, for instance, the opportunity to learn the capabilities of a power shovel without putting the driver, the environment or the machine at risk. To this end all vehicles from power shovels to trucks are simulated to the extent that is necessary for realistic training. The individual vehicles can moreover also interact with one another, so that the power shovel is also able to load the truck.
