The present invention provides a structure for fixing the hook cage provided on the deck of the high speed boat together with the hull so as to launch the high speed boat from the mother ship or lift the high speed boat to the mother side using a crane installed on the mother ship. As related, More specifically, the cage rod is connected to the fixing leg of the hook cage fixedly installed on the lower side of the deck, so that the cage rod is laminated with the deck integrally by the material for forming the deck (Laminating), In the bottom part of the hull, the casing rod part is laminated with the bottom part of the hull integrally and the rod casing is inserted and fixed in the state of interposing the adhesive, thereby improving the coupling strength between the hook cage and the hull high speed by the bus crane Allows stable transport of wells and does not form holes in hull The hook cage can be connected to the hull to prevent damage to the hull and water flow through the hull, while FRP (Fiber Reinforced Plastic) is applied to the hook cage and the hull to greatly reduce the weight of the high speed boat. It is related with the fast cage hook cage mounting structure.

In general, Rigid inflatable boats (RIBs) are used as small motorboats for rapid lifesaving and remediation in case of a marine accident. In addition, the mother ship is equipped with a crane to raise and lower the high speed boat to recover the high speed boat returning to the bus after completing the mission.

In addition, four lifting ilinks (two on each side) are placed on the deck of the high speed boat so that the high speed fishing boat can be launched from the mother ship to the sea using the crane as described above, or the high speed fishing boat can be recovered by the mother ship. I-rink) is fixedly installed, and the hooks are connected to the four eye links so that the hooks are positioned at the center of the high speed boat, and the hooks are connected to the connection ropes or connection rings of the bus crane. By catching, it is made to raise and lower the high speed boat according to the operation of the bus mother crane.

However, in order to ascend and descend the high speed by the four lifting eye links as described above, a person boards the high speed tack and connects the tow lines to the four lifting eye links one by one, and then the hooks to which the respective tow lines are bound. The connection ropes and connection rings of the bus cranes must be connected to each other, which makes the procedures for launching and lifting high speed boats difficult and the working time longer, as well as only when the bus and the high speed boats are stopped. There was a problem that work was possible.

In order to solve the above problems, the lifting hook cage is mounted on the deck of a small motor boat, such as a high speed gearhead, and the motor boat is connected to the bus crane by only one connection work between the bus crane and the lifting hook cage. Motor boats equipped with lifting hook cages, which can be lifted and lowered, and are capable of launching and lifting motor boats even during operation of bus and motor boats, are registered in Korea Utility Model Publication No. 20-0265781. : February 08, 2002).
