FOLDABLE RAMP

摘要

The invention concerns a foldable ramp (1) for relocation of material between a first level of height and a second, elevated level of height. The ramp (1) is assembled by several coupling parts (2), wherein each coupling part comprises a close to rectangular transport surface (3) and two coupling links (4) oriented parallel with said transport surface (3). Each coupling link (4) comprises at least one rotation opening (10) for coupling of each coupling link (4) to at least one adjacent coupling link (4) by insertion of at least one main fixing device (11) therethrough. The ramp (1) is further characterized in that the close to rectangular transport surface (3) of each coupling part (2) comprises two layers that are closed in longitudinal and height direction, and two sides that are completely or partly open in the transversal direction. Furthermore, the coupling links (4) in each coupling part (2) overlap with the adjacent coupling link(s) (4) when connected, wherein the overlap in height direction extends from the upper, outer surface (21) of the coupling link (4), to the lower, outer surface (22) of the coupling link (4), when the ramp (1) is completely unfolded. In addition, each of the coupling links (4) is designed with at least one main recess (8) in one end of the coupling link (4) and at least one main protrusion (9) in the opposite end of the coupling link (4), and with a shape rendering alignment of the two sides of the coupling link (4) in the transversal direction with the corresponding two transversal sides of the adjacent coupling link(s) (4) possible.
