An example of this type of parking device includes a plurality of pallets 10, a plurality of storage shelves 21, a lift cage 30, a wire 40, a hoisting device 50, and a cage support device 70.
The pallet 10 is a quadrilateral structure on which a vehicle is placed. Since the pallet 10 is convenient for handling vehicles of various types and sizes, a general parking apparatus uses the pallet 10 to handle the vehicle. Some parking devices handle vehicles without using a pallet.
A storage shelf is a shelf which can store a vehicle. A plurality of storage shelves 21 are arranged in the vertical direction. Usually, a plurality of parking shelves arranged vertically are arranged on the left and right sides of the hoistway. An entry / exit space S is provided in the middle of the hoistway H.

The wire 40 is a mechanical element that suspends the lift cage 30 along the storage shelf.
The hoisting device 50 is a device that can wind or unwind the wire 40.
The cage support device 70 is a device that supports the lift cage 30 on the building of the parking device when aligned next to one of the storage shelves.
The cage support device 70 supports the lift cage on the main structure by matching the rail surface level of the rail on the pallet in the lift cage with the rail surface level of the rail on the pallet in the storage shelf.

FIG. 6 is a perspective view of a conventional lifting device.
The hoisting device 50 includes a driving sheave 51, an idle sheave 52, a hoisting sheave 53, a turning sheave 55, a driving mechanism 56, and a counterweight 57.
Four hoisting sheaves 53 are arranged above the hoistway at positions facing the four corners of the lift cage 30.
Four sets of wires are connected to the lift cage 30 at one end, which is lowered downward from the hoisting sheave 53, and is horizontally stretched between the hoisting sheave 53 and the driving sheave 51. It is wound around the horizontal arc by 180 degrees or more, is wound around the idle sheave 52, and the end portion lowered from the idle sheave 52 is connected to the counterweight 57.
If such a structure is taken, the counterweight 57 will go up and down along the hoistway arranged in the vertical direction.

The operation when the vehicle is stored in the parking device will be described.
The vehicle self-propels into the lift cage 30 placed in the entry / exit space S.
The hoisting device 50 winds up the wire 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
The transfer device transfers the pallet on which the vehicle is placed to the storage shelf, and the warehousing is completed.

Next, the operation when the vehicle is taken out from the parking device will be described.
The hoisting device 50 winds up the wire 40 and stops the lift cage 30 next to one of the plurality of storage shelves. The cage support device 70 supports the lift cage 30 on the main structure of the building.
The transfer device transfers the pallet on which the vehicle is mounted from the storage shelf to the lift cage.
A cage support device disengages the lift cage.
The hoisting device 50 lowers the wire 40 and lowers the lift cage 30 to the loading / unloading space.
The vehicle runs out of the entry / exit space S.

In the parking apparatus using the elevating apparatus having the above structure, the elevating apparatus moves up and down along a storage shelf in which counterweights are arranged vertically.
As a result, problems may arise when planning many variations of parking devices using the lifting device having the above structure.
For example, there may be a case where a plurality of storage shelves arranged vertically are arranged in the front-rear direction and a plurality of lifting devices are arranged in the front-rear direction. In this case, since the counterweights move up and down between the storage shelves arranged in the front-rear direction, it is difficult to reciprocate the pallet between the storage shelves aligned in the front-rear direction.

  Further, since the lift cage moves up and down in the hoistway and the counterweight 57 moves up and down along the storage shelf, it is necessary to take safety measures at two locations.
