A port ramp (11) having a pontoon float (15), and forming a connecting path between a roll-on/roll-off ship (18) and a harbour installation (10) being subjected to variations in water level. A ramp bridge (11a) is vertically pivotably connected to the edge of the quay and to the pontoon float (15) respectively. Damping means (19) are mounted between the ramp bridge and the pontoon float, in order to slow down the speed of pivot angle variations between both said units, so that these together form an interconnected, rigid unit in relation to the load produced by vehicles intermittently moving over the pontoon float, as well as independently pivotable units in relation to the action of variations in water level, e.g. caused by the tides. |
