First, the communication frame 32 is supported by each arm receiving portion 40 on the entry / exit floor of the automobile and transferred to the entry / exit floor of the automobile, and then the tray on the turning frame 331. At the same time that Т reaches the car entry level on the car entry / exit floor, the tray Т is transferred from the turning frame 331 to the communication frame 32. The lift frame 3 is lowered to a predetermined height along the lift hoistway 20, and is separated from the communication frame 32 together with the tray turning device 33 on the lift frame 3. In this way, the communication frame 32 is delivered to the entry / exit floor of the automobile, and the tray Т is placed thereon, where the entry / exit of the automobile is performed.

  As described above, according to the lift 2, the lifting / lowering chain 24 such as the drive motor 25, the drive side sprockets 227 and 228, the drive chains 245 and 246, and the counterweight 23 is rotationally driven in the form of four pillars. The functional units necessary for the hoistway 20 are gathered on any one side of the hoistway 20, that is, any one of the four surfaces defining the hoistway 20, so that the hoisting drive mechanism of the hoisting frame 3 is simplified. The plane area of the lift 2 can be compressed. Furthermore, since the drive motor 25 is installed in the lower part of the hoistway 20, the installation and maintenance inspection work can be performed in a low place, and the burden caused by the conventional high place work can be greatly reduced to reduce the cost. Can do. In this case, since the single-axis drive motor 25 having a lower output than the conventional one can be adopted, it is cheaper than a large-capacity drive motor or a dual-axis motor, and power consumption can be kept low. Unlike the shaft drive motor, it does not require much labor for brake adjustment and replacement. As a whole, the cost can be greatly reduced. Further, the elevating drive mechanism of the elevating frame 3 is aggregated to any one of the four surfaces defining the hoistway 20, and selectively from one of the other three surfaces in one or more directions. Since a transfer route or a warehousing or leaving route can be formed, the lift 2 can be installed on the storage hierarchy of the vehicle or at an arbitrary position outside, and the direction of the vehicle entry / exit is arbitrarily set on the vehicle entry / exit floor be able to.

  In the case of the lift 2, in particular, since a plurality of sprockets 22 are all shared, parts management, maintenance, etc. are facilitated, and the counter weight 23 is single, so that the number of parts can be reduced. And cost can be reduced. Further, guide sprockets 225 and 226 are interposed between one driven sprocket 221 and 222 on one side and the other driven sprocket 223 and 224 on the other side, and spanned between each driven sprocket 221, 222, 223, and 224. Since each of the suspended suspension chains 241 and 242 is obliquely guided downward, the winding range of each of the suspended suspension chains 241 and 242 on each of the driven sprockets 221, 222, 223, and 224 can be increased. The power can be improved.

  Further, in the case of this lift 2, the communication frame 32 is transferred from the elevating frame 3 to the storage layer B1 or B2 of the loading / unloading destination, so that the interrupting portion of the tray circulation path 100 of the storage layer B1 or B2 is communicated. Since the entire circulation path 100 is made continuous, the tray Т can be circulated and moved on the tray circulation path 100 immediately when the communication frame 32 of the lift 2 is transferred to the storage layer B1 or B2 of the storage / reception destination. Since the hoistway 20 is opened in the storage hierarchy B2 or B1, the tray Т of the loading / unloading is moved on the communication frame 32 of the lift 2 in the storage hierarchy B1 or B2 of the loading / unloading destination. By lifting and lowering the lift 2, it can be transferred to the car entry / exit floor. Therefore, there is no useless operation in the overall operation of the parking facility 1, and the entering / exiting operation can be performed quickly and smoothly.

  In the above embodiment, the lift applied to the underground multi-layered horizontal circulation parking facility is illustrated, but four lifting guides are set up at the four corners of the hoistway and installed on these lifting guides. A type in which a plurality of lifting chains are wound around a plurality of sprockets, a lifting member for placing an automobile is connected to one end of each lifting chain, a counterweight is suspended at the other end, and the lift is driven by a drive motor with a speed reducer. The same applies to mechanical parking devices of various types, such as puzzle circulation type, plane reciprocation type, box type circulation type, elevator type, etc. It is possible to achieve the same operational effects.
