A PC base small-size excavator accident simulator was developed. This is based on a graphic workstation base large-size simulator. This was developed as a prototype of a simulator that will be used in training facilities, etc. This simulator has 4 projectors and a front screen, driver's seat with a motion device, and 5 PC. Performances of the small-size simulator that is necessary for training are nearly equal to that of the large-size simulator.
