40 is rotatably installed. (See FIG. 5) The size of the side plates 169 of the horse saddle 1010 is determined by appropriately setting the center angle α.

(See FIG. 6) Furthermore, one end of the flexible hose 105, which is supported at the upper middle part of the hose saddle 101 by a support section consisting of a large number of hose supporting horizontal rollers 102, is attached to a second
As shown in the figure, the other end is attached to a manifold 135 on a quay 130, and the other end is attached to a manifold 166 provided on a vessel or tank 166.
The fluid inside the tank is transported through a manifold 135 on the quay wall 130 for cargo handling operations.

In addition, the illustrated example shows a large number of horizontal rollers 102 for supporting hoses.
An example is shown in which the axis of the horizontal roller 102 at the center of the two is set on a common axis with the axis of the horizontal shaft 104 of the gate-shaped outer frame. FIG. 5 is a schematic plan view of the horse saddle 101,
Although the connecting material 103 is omitted from the illustration, as the ship or tank floats, the left side of the flexible hose 105 swings as shown by an arrow 141, and the vertical roller 140 and horizontal hose support It contacts rollers 102 and is supported on horse saddle 101 while moving in the direction of arrow 142.
