For this reason, in stormy weather, the hull sways under the influence of the waves, and a swaying motion is generated in the hanging tool (such as a hook). Conventional hull sway prevention measures include increasing the number of mooring lines to suppress sway of the hull, holding the hull with spuds,
There is a method of starting up on the water surface in SEP format.

ができる。As described above, according to the present invention, the legs of the bifurcated arm are connected to both sides of the jib via the universal joint, and the tips of the two legs of the bifurcated arm are connected with pins. Since this tip is connected to the hanging hook, the hanging hook is planar, and the legs of the bifurcated arm are hypotenuses.
It is held by a triangular component whose base is the width of the jib. Therefore, according to the present invention, even if the hull sways, the swaying of the hanging hook can be effectively prevented, thereby improving the safety of the slinging operation, improving the work efficiency, and improving the economic effect. Can be enhanced.

の左右方向の動揺を防止するものである。That is, the device of the present invention is intended to effectively and economically reduce the influence of the sway of a hull on a lifting device of a hoist ship or the like, thereby ensuring working functions and improving safety. The hull of a working boat such as a hoist ship usually has a ratio of length to width of 2: 1 or more and relatively little swaying in the front-rear direction. Therefore, in the present invention, the vertical movement of the hull in the front-rear direction is unique. It does not target the hull, but rather the sway of the hull in the left-right direction. Therefore, the sway described herein means the sway of the hull in the left-right direction, and the present invention mainly prevents the sway in the left-right direction.
