1. 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.
