The staff will retract the middle rail, upper platform rail post, and lower platform rail post, fold down the gangway handrail, insert the pin, and adjust the lower platform to a horizontal position. When the winch is started and the gangway is raised to a height of about 1.5 meters from the ladder frame, the winch stops working.

Use a marine ladder to first loosen the wing nut at the tightening fixing device, and then detach the fastening hook from the ladder. The workbench staff left the gangway and restarted the winch. When the gangway was lowered to the required position, the winch stopped working. The staff will install the platform railing, gangway handrail, middle rail rope, adjust the angle of the lower platform according to the installation requirements, and install the platform railing column and rail rope.

Start the winch, and the gangway relies on its own weight to move the ship ladder and the hoist arm outward. When the hoist arm rotates to a horizontal position and rests with the support seat, it stops rotating. At this point, the ship ladder has been completely poured out of the ship and is in a horizontal state. Then the ship ladder leaves the hoist arm and begins to descend. When it is about 1.5 meters away from the hoist arm, the winch stops working.
