In a foldable, modular scissor bridge (2) which can be transported in the folded-together state by means of a transport vehicle (1) and comprises two bridge modules (4, 4~) which are formed in each case by a pair or by two pairs of track carriers (6), it being possible for the track carriers (6) of each track carrier pair which are arranged at a spacing to be connected to one another by track carrier rods (7), and the bridge modules (4, 4~) having run- up ramps (9) at both ends, - all the run-up ramps (9) of both bridge modules (4, 4~) are connected rigidly to the bridge modules, - each run-up ramp (9) has, at its tip, a ramp termination tube (10) which is configured as a hinged part, - each run-up ramp (9) is provided with a coupling tab (11, 11~) at a spacing from its tip, - the coupling tab (11) of the upper bridge module (4) forms an articulated joint (5) with that ramp termination tube (10) of the lower bridge module (4~) which is configured as a hinged part.

L'invention concerne un pont à ciseaux (2) modulaire pliable et transportable sur un véhicule (1) une fois plié, ce pont comportant deux modules (4, 4') de pont chacun formé d'une paire ou de deux paires de porte-voies (6). Les porte-voies (6) de chaque paire sont espacés l'un de l'autre et peuvent être reliés par des barres (7). Les modules (4, 4') de pont sont équipés de rampes d'accès (9) à leurs deux extrémités. L'invention est caractérisée en ce que les rampes d'accès (9) des deux modules (4, 4') y sont reliées de manière fixe ; chaque rampe d'accès (9) comporte à son extrémité un tube d'extrémité (10) formant un élément charnière ; chaque rampe d'accès (9) est pourvue d'une chape d'attelage (11, 11') espacée de son extrémité ; la chape d'attelage (11) du module supérieur (4) crée une articulation (5) avec le tube d'extrémité (10) formant charnière du module inférieur (4').
