The invention reduces the use quantity of floating cranes and other equipment, has low cost, is easy to match with the auxiliary lifting hooks and the main lifting hooks by the auxiliary lifting hook steel wire rope 4 and the main lifting hook steel wire rope 7, reduces the occurrence of safety accidents such as collision and the like, and improves the safety.
8. The invention has the biggest core points that the invention improves the turning tool and the turning technology, which breaks the technical barrier that the main and auxiliary hooks of the conventional marine crane ship arm support are in the front-back direction and can not turn the single pile in the left-right direction, namely, the length direction of the single pile is perpendicular to the direction of the crane arm support, realizes that the marine crane ship with the main and auxiliary hooks of the crane arm support arranged in front-back direction can turn the single pile in the left-right direction, reduces the amplitude of the crane arm, greatly improves the lifting capacity of the crane under the construction operation condition, reduces the investment of a large auxiliary floating crane equipment, greatly reduces the cost and improves the safety.
While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
