Claims

[Scope of Claim for Utility Model Registration] 1. In the lifting rail 1, which has a plurality of rails diagonally installed in parallel from the seawall toward the water surface, the bogies 4, 14
Rear wheel running rails 2, 12 on which the rear wheels 5 run loosely
The inner front wheel running rails 3, 13, 23 on which the front wheels 6, 16, 26, 36 run are lowered to a lower lower position and are provided in parallel, and the rear wheel running rails 2, 12 and the front wheel running rails The front wheel running rails 3, 13, 23 are lowered from the rear wheel running rails 2, 12 until the height positions of the front and rear wheels running on the rails 3, 13, 23 are always maintained at the same height in the lateral direction. A boat lifting device characterized by being installed at a low position. 2. The lifting and lowering device for a watercraft according to claim 1, wherein the floating body 7 that supports one end of the lifting rail is formed in a substantially inverted triangular shape. 3 Connect the end of the rear wheel running rail 12 to the front wheel running rail 2.
2. The lifting and lowering device for a watercraft according to claim 1, wherein the inclined guide portion 9 is formed by being longer than 3 and greatly curved downward. 4. The lifting and lowering device for a watercraft according to claim 1, wherein the support member 24 of the front wheel 26 is fitted to slide back and forth within the guide tube 25. 5. A lifting device for a watercraft according to claim 1, wherein the support member 34 of the front wheel 36 is fixed to the lower end of the rotating shaft 33 diagonally downward.
