A blade control device comprises a change-over switch for providing light receiving position deviation signal sent out from a light receiving device into a light receiving device control system as a command value, and a device for measuring the change in the height of the light receiving device, whereby a topographic survey is conducted based on the height change of the light receiving device. The blade control device may further be provided with a second change-over switch for providing the command value outputted from a manual command value setter during a manual operation into the light receiving device control system, whereby returning the blade to a previous position is carried out in accordance with the operation of the second change-over switch. Further, the blade position can be determined by providing an adder for adding light receiving position deviation and the operation stroke of the lift cylinder at a light receiving time and a detector for detecting the deviation between the added result by the adder and the operation stroke of the lift cylinder at the current time, and by reducing the deviation to zero.

An unmanned conveying control system capable of conveying a load between a base position such as a gateway of a warehouse or a predetermined position in a manufacture line in a factory and a storage place in the warehouse or factory as well as loading and unloading of the load in such base position and storage place completely automatically and without an operator. A load conveying way is defined by leader cables along which an unmanned travelling vehicle is guided. Leader cables are provided along load storage lines (lanes) in the warehouse or factory and a central control unit gives out load storage and load delivery instructions and applies a guide signal only to a lane in which the vehicle should be guided. The vehicle detects the state of the load placed in front of the vehicle and transfers the load from the vehicle to a required layer of a stacked load when the vehicle has received the load storage instruction, or from a required layer to the vehicle when it has received the load delivery instruction. The loading and unloading operations of the vehicle and forward and reverse movements and stopping of the vehicle required for such loading and unloading operations are all performed automatically.
