AI Technical Summary
When modern ships transport debris, they encounter problems that heavy debris are difficult to lift and move, and the distribution of different types of debris is not fixed, which increases the difficulty of handling. The existing lifting equipment is fixed in a specific area, with poor stability and easy to shake.
A marine movable debris crane is designed, which adopts a combined structure of base, base plate, base rod, vertical spring and transverse spring. Combined with electric rotating disc, hydraulic push rod and winch, a buffer structure and multi-function spreader are formed to achieve the stability of the equipment and the large-scale lifting capacity.
The buffer structure effectively offsets the bumpy feeling during the ship's driving process, improves equipment stability, reduces the difficulty of lifting, and achieves the effect of easy lifting and time-saving, which is suitable for the water operation needs of small ships.
