A dolly has a carrying frame (1) provided with a scoop (2) which is coupled to an end of said frame in such a way that it can pivot about a pivoting axis (3). The scoop is movably coupled, by a control mechanism, to two wheel carriers which can be respectively pivoted about a bearing axis extending transversally in relation to the pivoting axis (3) of the scoop and which carry running wheels (4), in such a way that when the scoop is pivoted, the wheel carriers pivot out of a storage position oriented parallel to the carrying frame (1), into a use positio...


The invention claimed is: 1. A dolly, comprising: a carrying frame, at one end of which is articulated a scoop configured to be pivoted about a pivot axis and is coupled for movement, via a gear mechanism, to two wheel carriers, each configured to be pivoted about a bearing axis extending transversely to the pivot axis of the scoop and carry running wheels, such that, during pivoting of the scoop, the wheel carriers are pivotable between: (i) a storage position, in which the wheel carriers are oriented parallel to the carrying frame; and (ii) a use posi...
