(Prior art) Conventionally, as a vehicle elevating device used in this type of multi-level parking system, a method using a hydraulic device and a method using a chain device are generally widely known to raise and lower the pallet of the vehicle mounting platform. However, in either system, the device has a complicated mechanism and must be large, and the device is also quite expensive, so there is a problem that it can only be used for multilevel parking systems that can accommodate a considerable number of cars.

In addition, since the turning radius of large vehicles such as trucks is considerably larger than that of passenger cars, multilevel parking systems using elevating devices as described above waste a large amount of space, making it uneconomical in practice. The conventional multi-level parking system requires a larger amount of wasted space, making it impossible to install such a multi-level parking system for trucks in the city center. Due to this current situation, truck transport companies have the problem of having to transport trucks from the city center to remote locations outside the city center for truck storage, and maintenance costs such as rental fees are also high.

A pair of lower rear sheaves and a lower front sheave at corresponding positions, respectively, and two lifting wires hung from the upper sheave and the drum provided on both sides of the frame are used to balance the pallet on the vehicle platform. The pallet and balance weight are suspended by connecting the left and right sides of the pallet and the balance weight, respectively, and two connecting wires are used to connect the pallet and balance weight to the bottom through the lower front sheave and the lower rear sheave. A hoisting device that lifts and lowers the pallet and balance weight in opposite directions by the rotation of the drum by a hoisting mechanism whose sides are connected and the whole is connected in a loop shape; It is characterized by being a multi-level parking device, in which the pallet of the vehicle platform and the balance weight are suspended by wires hung in a loop between the drums and sheaves on both sides, and are raised and lowered. The present invention is characterized by a wire-type simple structure equipped with a hoisting device and a multi-level parking device for lifting and lowering vehicles such as trucks.

Next, a second invention, in addition to the structure of the first invention, includes a pallet fall prevention device comprising locking pieces that are movable back and forth to support the pallet from below at a predetermined height position on each of the pillars when the pallet is raised. and a pallet roll prevention device that guides the pallet up and down on the rails of each support with guide rollers provided on both front and rear sides of the pallet.
