AI Technical Summary
The existing fixed column setup of marine cranes requires maintenance to be performed at height and lacks internal support structure, affecting ease of use and safety.
A manually rotating ship-specific crane was designed. By setting a turntable and rotating column on the bottom plate, and connecting it with a mounting frame and connecting column, the crane boom can be flipped and its angle adjusted using components such as fixing blocks, locking nuts and support rods. The stability is enhanced by combining telescopic rods and gear transmission.
This eliminates the need for climbing to perform maintenance, improves operational safety and support strength, and enhances the convenience and stability of angle adjustment during hoisting.

TECHNICAL FIELD
[0001] The utility model relates to a ship crane technical field, more specifically to a hand rotating ship special hoist. BACKGROUND
[0002] The ship crane is a mechanical device used for lifting and handling goods on a sea transport ship, and is generally installed on a large cargo ship. The ship crane comprises a base welded on a deck base of the ship and a stand fixed on the base. A telescopic boom controlled by an oil cylinder is hinged to the top of the stand. A lifting winch is installed at the lower end of the telescopic boom. The crane has a mechanical structure in which the base and the stand are fixedly connected, the pump station is installed on the deck, and the boom cannot be folded. Therefore, the telescopic boom can only be extended and retracted in one direction. This not only makes the crane inconvenient to use and affects the work efficiency, but also occupies a large space and has a large windward area, which affects the speed of the ship. Although the crane with the above structure is practical on a large ship, it is not practical on a small ship because the load capacity of the small ship is small. The crane cannot be folded, which increases the occupied area and the windward area of the extended boom, which not only affects the speed of the ship, but also causes the ship to tilt.
