Abstract
The invention provides a transport dolly for the transport of cuboid boxes and stackable transport containers in which the upper side is used as a bearing surface for the items to be transported. The transport dolly comprises a substantially rectangular support floor which is rollable on wheels and comprises anti-slip devices. An extendable additional element is provided on each of the two transverse ends of the support floor, which additional element can be flipped outwardly by 180°. The lateral extension of the additional elements produces an enlargement of the bearing surface of the support floor. Upwardly projecting stop edges are shaped on the upper edge of the two longitudinal sides of the support floor. The additional elements, which are laterally hinge-fixed to the support floor by means of bolts in recesses of the support floor, have a thickness which ensures that, when the additional elements are retracted, the recess in the support floor is filled and the upper side of the additional element forms part of the bearing surface.
