Background

The cutter suction dredger is an engineering ship which is applied to the engineering fields of dredging channels, sea reclamation and the like at present. Generally, a cutter suction dredger excavates silt and stones through a reamer, then conveys the silt and stones into a mud pipe on the dredger, and conveys the silt and stones to a designated area through a conveying pipeline which is connected with the dredger and arranged on the sea. However, in special cases, there is the possibility of: there is no suitable area for storing the silt and stone excavated by the cutter suction dredger, or the designated storage area is too far from the operation site of the dredger to exceed the range of the transporting capacity of the cutter suction dredger itself. At this time, a transportation barge is required to be matched with the cutter suction dredger to transport the silt and the stones excavated by the cutter suction dredger to a specified place.

As the cutter suction dredger is generally provided with more construction equipment and devices, the deck area is tense, and the existing loading and unloading device has larger volume and complex structure.
