Abstract

PROBLEM TO BE SOLVED: To securely prevent incorrect supply of oil, by constituting an opening handle of a bottom valve of every kind of oil of a tank lorry so as to exclusively fit to one driving shaft and judging coincidence of the kind of oil in a hatch and the kind of oil in the oil storage tank and fixing the handle to an unlocking means. SOLUTION: A selection means 41 for kinds of oil reads out oil kind data in a memory 43 on the basis of a hatch number from a keyboard 42 of a controller and outputs it to a judge means 44 for coincidence of kinds of oil. The judge means 44 compares the oil kind data from a receiving means 45 of oil kind signals, receiving the signals transmitted from the reading-out means of a discrimination piece attached to an oil supply hose, with the oil kind data read out of the memory 43. When the data coincide with each other, a signal is output to a control means 46 of a lock member and a display 47. Then, one of lock members 32-34 of handles 29-31 opening/closing hatches designated at the keyboard at every oil kind is selected and unlocked by the control means 46. In this way, oil can be supplied in an oil-storage tank in a gas station.
