2. Description of the Related Art Conventionally, a method of hoisting a boat such as a yacht, a boat, or a marine vehicle is roughly classified into a jib type jib crane type, a traveling gantry type, a fixed gantry type, and other trolley type. Each of these has advantages and disadvantages, and is selected according to the situation of the marina, quay, size, and other equipment conditions. However, in general, hoisting boats are stored on land (land) via a hoisting device (landing,
For hoisting and collecting boats, the method of transferring using a trolley or using a traveling gantry is adopted. Therefore, it is necessary to secure a space in the boat shed where the carriage, the traveling gantry, etc. move. Since this space is used only for movement, it is very wasteful, and there is a strong demand for effective use or elimination of the wasteful space.

Of course, landing on the first boat depot is not limited to this, and in the case of this example, the slide rail is used. Since it is also possible to land at the second boat depot, the landing at the second boat depot will be described as an example. As described above, in order to transfer the first boat hull or the boat hoisted at sea via the lift device (hereinafter, in principle, the first boat hull is described) to the second boat hull, As a requirement, it is necessary to move the lift device along the slide rail, and the second requirement is that the wheels be rotatable in the horizontal direction. Therefore, in the illustrated example, the wheels provided at the lower ends of the support poles are rotated in the direction in which they are juxtaposed to the slide rails, and in principle fixed in the juxtaposed direction position, and while maintaining this state, the Through the movement of the center pole (either manually or automatically possible), the lift device is moved and transferred to the second boat storage. After that, although the boat is descended, the operation and procedure are the same as in the above-mentioned example. It is of course possible to land the first and second boat sheds in the intermediate zone.

The operations and procedures such as landing and transfer to the sea, which have been described in detail above, are examples, and are the easiest to understand and explain basic landing and the like, and are not limited to these examples. Needless to say, the method of use and the configuration for landing a boat through the lift device and / or the slide rail are included in the scope of the present invention.
