Abstract

The ramp assembly of a ro-ro type ferry having two cargo receiving decks comprises at least two sections (14, 15, 16) and is pivotally connected to the lower (11) of the decks. An inner section (14) of the ramp assembly (13) has a length which corresponds essentially to the tween deck height and can be raised by approximately 90 ° with respect to the lower deck (11) in order to support the upper deck (10) when the latter should be accessible. A portion of the upper deck (10) is formed as a platform (21) which is pivotable about a transverse axis (22) so that it can be folded down to rest on the raised, inner portion (14) of the ramp assembly.

the load caused by vehicles driving over a larger area is distributed on the quay.

The ramp 13 is connected to the lower deck 11 by means of a hinge 20. The total length of the Sections 14 and 15 is larger than that of section 16 plus the end flaps 19. The hinge 17 allows a folding movement of 90 °, while the hinge 18 allows a folding movement of about 180 °, so that the ramp 13 can be folded up into a substantially vertical position while driving (Fig. 3). If the end flaps 19 are folded in with respect to the adjacent ramp section 16 can, this outer section 16 can have a length extension which is substantially the entire length from inner section 14 and middle section 15 corresponds.

The inner portion 14 of the ramp 13 has a length which is substantially the height between the upper deck 10 and the lower deck U corresponds to In in FIG. 1, the ramp 13 serves as the position shown Access to the upper deck 10 and the inner ramp section 14 is in a substantially vertical position Folded up It will then fit into the space below the front free edge of the upper deck 10 and will carry this when heavy vehicles get off the ramp onto the deck and vice versa.
