PROBLEM TO BE SOLVED: To provide a main control device that achieves improvement in safety.SOLUTION: A comparison operation unit 4 compares the vehicle speed detected by a speed detecting unit 2 with the speed limit for each of a plurality of notch stages stored in a storage unit 3 and settable with a command handle 1. When the vehicle speed detected by the speed detecting unit 2 exceeds the speed limit stored in the storage unit 3 and corresponding to the notch stage currently set with the command handle 1, a power running command to a power running circuit 5 is interrupted. |
