The boarding unit 120 may be a rectangular hexahedron structure having a work space 121 on which an operator can be carried and perform maintenance work. In addition, the passenger compartment 120 has a side surface and an upper surface opposite to the outer surface of the hull 10, and the other side surface and bottom surface are closed. Here, the hexahedral passenger 120 is shown as an example, but the form of the passenger is not limited thereto, and may be a semi-cylindrical structure having a curved surface on the other side except for the open part.

The elevating device 110 may be constructed of a crane fixed to the top of the quay wall 20 of the quay and having a plurality of boom rods 111 and a plurality of hoist devices 112. The lifting and lowering device 110 can elevate and lower the vehicle body 120 in such a manner that the wire rope 113 connected to both sides of the vehicle body 120 is wound or unwound by the winding device 112, The position of the passenger 120 can be adjusted by adjusting the angle and the length.

Here, the elevating apparatus 110 fixed to the upper part of the quay front wall 20 is shown. However, the elevating apparatus 110 may be a mobile crane mounted on a transportation apparatus such as a vehicle or a crane installed on a ship or an offshore structure.

The suction unit 130 may be provided along the open side edge of the passenger compartment 120, as shown in FIGS. As shown in FIG. 6, the adsorption unit 130 is made of an elastic material such as rubber or silicone, and is installed continuously along the opened side edge of the passenger compartment 120, A plurality of adsorption pumps 133 for discharging the fluid in the adsorption space 132 to realize the adsorption of the adsorption member 131 and a plurality of adsorption pumps 133 installed in the adsorption space 132, And a plurality of adsorption pads 134 having a plurality of inlets associated with the adsorption pads 134.
