PROBLEM TO BE SOLVED: To prevent upper side lifting vehicle support stands and lower side lifting vehicle support stands from interfering with each other by hanging up the lower side lifting vehicle support stands existing on a lower side vehicle support level up to a vehicle deliverying/receiving level via hanging-up connecting means switched to an action state when the upper side lifting vehicle support stands rise to an upper side vehicle support level from the vehicle delivering/receiving level. SOLUTION: Lower side lifting vehicle support stands 3A to 3C arranged so as to be respectively separately liftable between a vehicle delivering/receiving level N and a lower side vehicle support level D are constituted so as to be hung up to the vehicle delivering/receiving level N from the lower side vehicle support level D via hanging-up connecting means 33A to 33C by upper side lifting vehicle support stands 1A to 1C respectively separately liftable between the vehicle delivering/receiving level N and an upper side vehicle support level U to thereby wholly eliminate the possibility that the upper side lifting vehicle support stands and the lower side lifting vehicle support stands interfere with each other by failure of a control system.
