Abstract: A gangway for embarking and disembarking passengers comprises a first module with a plurality of ramps located at different heights and joined at their ends by union modules, defining an entrance and an exit towards a second module, and a pair of movable support structures located at opposite ends of the first module. The second module comprises a plurality of telescopic tunnels that can be extended relative to one another, one of the ends of the outermost tunnel being coupled to a cabin that can be coupled to the ship; a movable gantry structure that allows the height of the second module to be regulated; and a motor-less revolving platform coupled to the first and second modules and supported on a movable support structure that rotates about its own vertical axis.
