Beschreibung
Zusammenfassung:	PURPOSE: To prevent the occurrence of an excess of a loading weight or the like and to ensure safety traveling by reading signals from an object detecting sensor and a piezoelectric sensor and stopping a carrier. CONSTITUTION: It is detected by an object detecting sensor 10 that the height of cargoes loaded on a load-carrying platform is equal to, or exceeds a given value. When the above-mentioned condition is detected, 5V is outputted from an object detecting sensor processing circuit 12 to an OR circuit 14, and when the above-mentioned condition is not detected, OV is outputted. Simultaneously, the weight of cargoes loaded on a load-carrying platform is detected by a piezoelectric sensor 11 arranged on the under surface of the load-carrying platform. 5V is outputted to an OR circuit 14 to detect a rated weight or more and when weight is below the rated weight, OV is outputted. The OR circuit 14 outputs 5V to a main control circuit 15 when 5V is outputted from either the object detecting sensor processing circuit 12 or a piezoelectric sensor processing circuit 13, but does not effect a duty output to the gate side of an FET16 and stops a motor 9. In this way, when either of them is detected, the motor 9 is stopped to ensure safety.
