The invention relates to a conveying device comprising a platform conveyor, which is provided with a plurality of rectangular platforms, each being flexible in one direction, and with two pairs of endless chains, the pairs being connected to the corners at the front and rear side, respectively, of the platforms and being led over pairs of aligned guide sprockets, the chains extending substantially parallel to each other and guiding the platforms in a substantially horizontal position from a load point to an unload point through a transport part and bringing them back through a return part, the transport part including a section having a substantial vertical component. According to the invention the platform conveyor includes a substantially horizontal section near the load or unload point, and at this load or unload point the platform conveyor is connectively coupled to an unload or load point of a similar second platform conveyor, the load or unload point thereof being lockable at a fixed level, the substantially horizontal sections of both platform conveyors, which are connected to each other, together being adjustable in the vertical direction, and during the height adjustment the connecting point of both platform conveyors is movable in the substantially horizontal direction.
