After the ship is landed, a springboard needs to be erected between the ship and a dock in order to facilitate landing of personnel and vehicles or boarding. The gangway is usually arranged at the stern, or at the bow and the side, and when the ship is in the bank, the corresponding bow, stern or side is close to the bank. Before loading and unloading operation of the ship, the springboard is firstly put down and lapped on the ground of a dock, and containers, tray goods, vehicles and mechanical equipment are loaded or unloaded by utilizing rolling loading and unloading tools such as a trailer and a forklift or by means of a vehicle to pass through the springboard of a bow opening, a stern opening or a side opening.

The form of the springboard is generally three: the straight springboard is arranged along the length direction of the ship, and vehicles can alternately run up and down; the inclined springboard forms a certain included angle with the central line of the ship body and consists of a plurality of sections of springboards; the rotary gangplank can rotate a certain angle to two sides of the ship body and can be used on any side of the ship.

The three types of springboards are plate bodies essentially, and when the three types of springboards are used, one end of each springboard is lapped on the wharf ground, and the other end of each springboard is lapped and fixed on a ship. When the load on the springboard suddenly increases or suddenly decreases, the springboard is easy to bump relative to the roll-on-roll-off ship; meanwhile, when the sea storms are large and the ship rolls, the springboard is easy to incline transversely along with the ship, and vehicles or personnel have large jolting and inclining risks when passing through the springboard, wherein the transverse direction is the water bank line direction of the wharf. Moreover, because the contact between the springboard and the dock ground is hard contact, violent relative motion exists between the springboard and the dock ground when the springboard jolts, so that the springboard is easy to collide with the dock ground to generate larger abrasion, and the service life of the springboard is shortened.
