In addition, it is to be checked whether the setting of bulwark doors meets the requirements of the drawings, so as to facilitate the boarding of the pilot.
Check the flexibility of the gangway, such as turning and turning over, and make a strength test. For new ladders: the gangway should be at an angle of 60° to the horizontal, and a load of 150kg should be placed on the odd steps and the lower platform of the ladder, and a load of 300 tons should be placed on the upper platform for 15 minutes. After the load is removed, the rotating parts of the gangway should be kept Flexible, each part should be free of defects or obvious deformation; for the repaired gangway: the gangway should be placed 0.5m above the summer load waterline, with a load of 75kg on each step or 150kg on every other step, and 150kg on the upper and lower platforms. load, lasting 30min in a static state, there should be no permanent deformation or other defects.
