Next, the operation of the device of the present invention constructed as described above will be described. As shown in FIG. 4, the adsorption type mooring device which also serves as a fender of the present invention is usually installed on the mooring facility 2 in the required number. To moor the hull 3, first, the hydraulic cylinder 14 is operated to set the suction plate 28 to a desired height.
Normally set to low position when there is a lot of cargo and low tide, and set to high position when empty and high tide. 1, 2 and 5 show a state in which the suction plate 28 is in the lower position, to raise the suction plate 28 from this state, the hydraulic cylinder 14 is operated to lower the piston rod 14a. When the piston rod 14a descends, the pulley 17 moves to the position indicated by the chain double-dashed line in FIG. 1, and as a result, the pulley 23 pivotally supported by the elevating member 9 via the rope 24 is raised, and the elevating member 9 is also pulled up. If the lifting member 9 rises,
Along with that, the suction plate 28 also rises. To lower the suction plate 28, the above operation may be reversed.
