Claim:
Mobile bridge ( 6 ) of great length as a support construction for at least one transport means, having at least two bridge segments ( 5 ) disposed in a row one behind the other, which are connected with one another at their faces, wherein the bridge ( 6 ), in its totality, forms a multi-member system in the vertical plane, and a continuous carrier in the horizontal plane, wherein the at least two bridge segments ( 5 ) of the bridge ( 6 ) are connected with one another, in the vertical plane, wherein the bridge ( 6 ) is supported by means of at least three bearing mechanisms of a type A, B, and C which are carried by a self-propelled, tip-proof traveling mechanism ( 8 ), whereby at least one bridge segment ( 5 ) has both a traveling mechanism ( 8 ) having a bearing mechanism of the type A, and a traveling mechanism ( 8 ) having a bearing mechanism of the type B, and at least one other bridge segment ( 5 ) is provided with a traveling mechanism ( 8 ) having a bearing mechanism of the type C, while all the other possible bridge segments ( 5 ) have a traveling mechanism ( 8 ) having a bearing mechanism of the type A, and whereby the bearing mechanism of the type A is configured in such a manner that it permits displaceability of the bridge segment ( 5 ) relative to the assigned traveling mechanism ( 8 ), both in the longitudinal direction and in the transverse direction of the bridge segment ( 5 ), as well as a pivoting movement about a horizontal pivot axis ( 14 ) oriented transverse to the longitudinal direction of the bridge segment ( 5 ), the bearing mechanism of the type B is configured in such a manner that it permits a pivoting movement of the bridge segment ( 5 ) relative to the assigned traveling mechanism ( 8 ), about a horizontal pivot axis ( 14 ) oriented transverse to the longitudinal direction of the bridge segment ( 5 ), and the bearing mechanism of the type C is configured in such a manner that it permits displaceability of the bridge segment ( 5 ) in question, relative to the assigned traveling mechanism ( 8 ), within limits, in the longitudinal direction of the bridge segment ( 5 ), as well as a pivoting movement of same about a horizontal pivot axis ( 14 ) oriented transverse to the longitudinal direction of the bridge segment ( 5 ); and wherein the traveling mechanisms ( 8 ) having the bearing mechanisms of the type A are operated independently of the traveling mechanisms ( 8 ) having the bearing mechanism of the type B and C, in terms of regulation and control technology, while the traveling mechanisms ( 8 ) having the bearing mechanism of the type B and C are connected with one another in terms of regulation and control technology.
