<p>A transportation barge is provided with a load table and an actuator group which drives the load table to move up and down. It is possible to move down the load table when hoisting the transportation freight from the load table. Therefore, the influence of heaving of the transportation barge due to waves can be eased without jacking up the transportation barge to the sea bottom. Therefore, a collision of the transportation freight and the load table can be prevented when hoisting the transportation freight, and the time of jacking-up and the use cost of the transportation barge provided with the expensive jack-up unit can be reduced.</p> |
