A large water tank is set on the side of the hull away from the main boom, and counterweight is achieved by filling or pumping water into the water tank, thereby achieving the balance of the entire floating crane. The structure is low-cost and can use water bodies in rivers and seas to achieve cost-free counterweight. In the process of counterweighting by utilizing the change of water level inside the water tank, it is only necessary to turn on the water pump or the drainage pump, and adjust the water level according to the weight of the hoisted cargo. The whole process does not require physical labor, freeing the hands of the staff and saving physical strength for later operations.

[0004] However, the above patent is unable to crush and filter the aquatic plants or debris in the water entering the water inlet pipe, which may cause the aquatic plants or debris to clog the water inlet pipe, affecting the use of the water inlet pipe and reducing the balance of the floating crane.
