A system for operating a vehicle storage conveyor is disclosed in which a programmable digital computer system is used to automatically control the operation of the conveyor, to monitor the safeties of the storage conveyor and to cease operation thereof upon the detection of an unsafe condition, and for controlling a plurality of electromagnetic radiation beam transmitting and detecting devices systematically located throughout a loading area of the storage conveyor so as to detect the presence of a vehicle or a person and to distinguish between them. The system prevents operation of the vehicle conveyor until the vehicle is properly positioned thereon and the person who drove the vehicle is detected as leaving the conveyor loading system.
