Abstract

The present invention relates to a grapple device, preferably designed to load and unload pulpwood or bulk material, including two towards each other movable prongs or bucket halves being connected at their upper ends to a central shaft. The invention is characterized in that a knee-joint mechanism (4, 5) is connected between prongs (1, 2) or bucket halves (1, 2) at both sides of their central shaft (3), and that at least one force performing device (7) is connected between the knee-joint mechanism and one of the prongs (2).
