Based on the detection signal of the
The carriage is controlled, and the car 3 is transported and stored in the garage having a height corresponding to the height.

For example, when the car 3 is lower than the height position of the photoelectric sensor S1, the control device 7 controls the lifting device 1 and the carriage, the lifting device 1 lifts the car 3, and the carriage 3 conveys the car 3. Of the three types of garages with different heights, the car is stored in the lowest garage. Then, when the vehicle 3 is higher than the height position of the photoelectric sensor S1 and crosses the straight line L1, the photoelectric sensor S1 detects it, and based on the detection signal of the photoelectric sensor S1, the control device 7 causes the lifting device 1 and The dolly is controlled and the car 3 is stored in the next lower garage. Further, when the car 3 is higher than the height position of the photoelectric sensor S2 and crosses the straight line L2, it is detected by the photoelectric sensor S2, and based on the detection signal of the photoelectric sensor S2, the control device 7 causes the lifting device 1 and The dolly is controlled and the car 3 is stored in the highest garage.

Therefore, the vehicle 3 can be stored in the garage having a height corresponding to the height. Therefore, when the car 3 is stored in the garage, there is no possibility that it will contact the components of the garage near the roof of the car 3,
Car 3 is not damaged.

Therefore, it is possible to prevent an accident due to the half door of the vehicle 3. For example, there is no possibility that the vehicle 3 is lifted in a half-door state and the right door contacts a component of the hoistway in the hoistway of the hoisting device, thereby damaging the car 3. The right door does not come into contact with the constituent members of the hoistway, and in that state the lifting device 1 and the car 3 ascend, so that the car does not overturn or fall.
When the vehicle 3 is transported in the half-door state and stored in the garage, there is no possibility that the right door will contact the components of the garage.

It is also conceivable that the right door is almost closed and the photoelectric sensor S1 does not detect it even in the half-door state. In this case, there is no problem if the car 3 is lifted as it is and stored in the garage,
When the car 3 is lifted by the lifting device 1, the impact may cause the right door to open. Therefore, in this embodiment, after the lifting device 1 is driven, the right door opens due to an impact, and when the right door crosses the straight line L5 of the photoelectric sensor S5 or the straight line L6 of the photoelectric sensor S6, the photoelectric sensor S5
Alternatively, the photoelectric sensor S6 detects it, and based on the detection signal, the controller 7 controls the lifting device 1 to stop. Therefore, the car 3 cannot be lifted any further. Further, in this embodiment, the photoelectric sensor S
Based on the detection signals of S4, S5 and S6, the alarm device is driven by the control device 7 to give an alarm of the half-door state. Then, when the right door of the car 3 on the lifting device 1 is completely closed and then the lifting device 1 is driven by the operation panel,
The lifting device 1 lifts the pallet 4 and the car 3.

In this embodiment, the multi-storey parking lot for raising the car 3 to the second floor or higher floors of the building has been described, but the present invention is not limited thereto. On the first floor of the building, the vehicle 3 is placed on the lifting device 1, and the height of the vehicle 3 is detected by the photoelectric sensors S1, S2, S3 in a multi-level parking lot in which the vehicle 3 is lowered to the basement of the building. It is also possible to control the lifting device 1 and the carriage to transport the car 3 to a garage having a height corresponding to the height and store the car.
