ABSTRACT:
The invention relates to an apparatus for transporting potted plants arranged according to at least one row, in which the apparatus lifts and transports the plant pots and fits them to a fork lift truck. The invention provides elongate cariers, wherein the interval between these carriers is smaller than the diameter at the top of the plant pot but greater than the diameter on the underside of the plant pot. This allows the apparatus to be displaced in the horizontal direction which contacts the plant pots, but also to lift the row of plant pots. According to a preferred embodiment the device is provided with two bearing surfaces for the plant pots. This doubles the carrying capacity of the apparatus. According to another preferred embodiment, said elongate carrier comprises disconnecting mechanism, allowing it to pick up only a limited number of plant pots in a row, for instance only every second plant pot. This allows decreasing the density of the plant pots.
