Disclosed herein is a folding transport cart which in a parking configuration has a minimum extension and in an operative configuration has a maximum extension in a transverse direction. A folding transport cart can comprise: two side parts which extend substantially perpendicular to the transverse direction of the transport cart, and a folding base part which comprises two flat base segments which are each connected on one base side axis for articulated movement to one side part and are connected on a common base central axis for articulated movement to one another. In order to ensure reliable folding and unfolding the transport cart can comprise a base locking mechanism for locking the folding base part in the operative configuration and a cover part which is connected for articulated movement to one of the side parts.
