2. Description of the Related Art Elevating devices are widely used when parking cars in a multi-storey car park. In a lift-type multi-level parking lot, when a car is stored, for example, on the first floor of a building, the car is placed on the lift. Usually, a pallet is placed on the lifting device and the car is placed on the pallet. After that, the pallet and the car are lifted and lifted by the lifting device, and the pallet and the car are handed over to the trolley on the second floor or higher floors of the building, the trolley moves horizontally, and the pallet and the car are transported by the trolley. To be done. Further, the pallet and the car are delivered to the garage and stored. Then, when the car is unloaded, the pallet and the car are delivered to the dolly, the pallet and the car are transported by the dolly, and the pallet and the car are delivered to the elevating device, which descends to the first floor of the building.

By the way, an unexpected accident may occur in a multi-storey car park, and one of the most frequent causes is the half-door state of the car. Due to the nature of the multi-storey car park, it is required to use the space as effectively as possible, and it is not appropriate to make the space for the hoistway of the lifting device and the garage larger than necessary. Usually it is only slightly larger than the size of the car. For this reason, it is extremely important that the vehicle placed on the lifting device is in a half-door state when the vehicle is loaded. For right-hand drive cars, the driver gets off the right door of the car,
For that reason, the right door is often a half-door state,
In the case of the half-door state, when the vehicle is lifted by the lifting device, in the hoistway of the lifting device, the right door may contact a component member of the hoistway, and the impact may damage the right door. The right door contacts the hoistway components,
In this state, the lifting device and the car ascend, which may cause the car to capsize or even fall. When the vehicle is stored in the garage, the right door may come into contact with the components of the garage, and the impact may damage the right door. This problem is serious for users and managers of multilevel parking lots, and it has been demanded to take measures against it. Here, the half-door state means all states in which the car door is not completely closed.
