<p>The double platform is formed by two twin and specular structures each one equipped with a board (1, 2) and a base (3, 4); each board (1, 2) serves as a base for pillars on which are steadily fixed upper beams forming railings (5) and height-adjustable lower beams (6) set between the railings (5) and the board (1, 2); the railings (5) of each platform create a basket open on the side facing the other platform; each board (1, 2) is linked to the corresponding base (3, 4) through a tubular element (7, 8) adjustable in height through dowel pins (9); each base (3, 4) is equipped whether with rubber feet (14) and rotating elements (13) or with single or paired rotating elements (13); in each pair, one rotating element (13.1, 13.2) is set after the other (13.2, 13.1) and the longitudinal axis of each pair is parallel to a longitudinal axis of the base (3, 4).</p> |
