A carriage is intended to be disposed transversely between essentially-parallel lateral girders. The carriage comprises: stirrups which are disposed at the lateral ends and which each cooperate with a lateral girder in order to enable the movement of the carriage along the longitudinal axis (x) of the lateral girders; a central girder which is placed between the stirrups; first connecting means which are provided between a first lateral end of the central girder and the first stirrup, and second connecting means which are provided between a second lateral end of the central girder and the second stirrup. The aforementioned connecting means are arranged such as to enable the movement of one stirrup in relation to the other with six degrees of freedom and a limited amplitude.
