<p>A bridge part (1) is articulated, so as to be adjustable in terms of inclination, on a mole (M) by means of a support (15) attached to solid foundations (F). The bridge part (1) is constructed in the form of a four-armed parallelogram, and its outer end is fastened to a portal frame (8) which slides, in terms of height, in a support (3). An overhanging horizontal handrail part (2) is fastened to the portal frame (8). By adjusting the height of the portal frame (8), in the support (3), it is possible to move the handrail part (2) relative to the level of the surface of the water. <IMAGE></p> |
