摘要

Improvements to the rolling tracks of the bridges to be taken up in a shell comprising, at each of their ends, a flap (2) mounted to pivot about an axis (3) of said end extending perpendicularly to the longitudinal axis of the rolling track, means being inserted between the flap and the rolling track, so that said flap to pivot freely and, on the other hand, be mounted in an angular position in which it extends in the extension of the rolling track, and improvements which are characterized in that said means comprise a strut (8) is articulated at one end on the end of the rolling path (1) and the other end of which is capable of cooperating, on the one hand, with a guide (12) arranged under the flap (2) to allow the free pivoting of the flap and, on the other hand, with a retaining member (14) so as to hold the flap (2) in the extension of the rolling path (1).
