<p>PROBLEM TO BE SOLVED: To provide an unmanned carriage and its operation control method which judges whether or not operation control for improving the positional relation between a fork and a loading palette is necessary and performs operation for improving the positional relation only when it is judged that the control is necessary. SOLUTION: This unmanned carriage 1 is equipped with an operation control means 6 which computes deviation x from a guide line 2 during a forward travel and corrects a travel posture according to the deviation x and stops traveling forward to perform loading operation or unloading operation. The operation control means 6 starts the loading operation or unloading operation at a forward-travel stop posture when the deviation at the stop of the forward travel is less than a prescribed value and repeats a backward travel or a forward travel by a set straight distance M until the deviation x becomes less than the prescribed value and starts the loading operation or unloading operation if the deviation x at the stop of the forward travel exceeds a prescribed value.</p> |
