Description
Technical Field
[0001] The utility model relates to the technical field of cargo ship hoisting, in particular to a small cargo ship hoisting reinforcement device. Background Art
[0002] A cargo ship is a means of transport that mainly carries cargo and can carry less than 12 passengers. Most of its cabin space is used for cargo storage. There are many types of cargo ships, with a wide range of sizes, and displacement can range from hundreds of tons to hundreds of thousands of tons. Cargo ships are generally equipped with cranes to transfer cargo, usually to transfer cargo on cargo ships to land, or to transfer cargo on cargo ships to other ships.
[0003] The cranes on traditional cargo ships usually directly fix the bottom mounting base on the deck of the cargo ship. The mounting base is fixed to the deck with bolts. There is a lack of reinforcement structure for the entire crane, resulting in all the force being concentrated on the bolts during the lifting process. If the mounting base is larger in size, it can provide good support, but a larger mounting base will also occupy a larger deck area. If a smaller mounting base is used, there will be a greater pressure burden on the mounting base and the fastening bolts above, so there are certain disadvantages in use. Utility Model Content

If the size of the mounting seat is larger, it can also play a good supporting effect, but the larger-sized mounting seat will also occupy a larger deck area. If a smaller mounting seat is used, there will be a problem of greater pressure burden on the mounting seat and the fastening bolts above.
