Traversing bridge which is mobile in translation or in rotation on a support

摘要

The present invention relates to a traversing bridge which is mobile in translation or in rotation on a support such as, for example, a supporting bracket, being designed to resist earthquakes. This traversing bridge is characterised in that each bent 4 is articulated in the longitudinal plane and carries, at its lower part, at least one grooved roller 6 capping the rail 2, each guiding roller 8 of vertical axis 9 is mounted at the lower end of a support 7 which is itself articulated, at its upper end, under the load beam 1 and means 12 are provided for elastically pressing each guiding roller 8 against the vertical bearing surface 10 of the support 3.
