1. A pallet for receiving and transporting loads, comprising:
- an upper platform for receiving the loads, the upper platform having an underside surface including a first plurality of groove-shaped connecting sections extending in the underside surface from a first side edge of the underside surface to an opposite second side edge of the underside surface;
a lower platform having a top side surface including a second plurality of groove-shaped connecting sections extending parallel to the first plurality of groove-shaped connecting sections and extending in the top side surface from a first side edge of the top side surface to an opposite second side edge of the top side surface;
a plurality of longitudinally extending strip-like support elements which are attachable to the underside surface of the upper platform and the top side surface of the lower platform, and each of the support elements extending from the first side edge of each of the upper platform and the lower platform to the opposite second side edge;
each of the support elements including a first counter-connecting section extending along a top portion and that is inserted into one of the first plurality of groove-shaped connecting sections to dispose the support elements parallel to one another;
each of the support elements including a second counter-connecting section extending along a bottom portion and that is inserted into one of the second plurality of groove-shaped connecting sections;
each of the supports elements having a profile section extending between the first and second counter-connecting sections and that includes one of an X-shaped, an S-shaped, a round or an oval cross-sectional structure, the profile section structure forming two longitudinally-extending hollow spaces, each of the longitudinally-extending hollow spaces extending a length of the support elements and having a length dimension that extends parallel to the upper and lower platforms;
wherein at least the support elements are made of polyurethane foam with hemp fibers embedded therein.

Abstract
A pallet for receiving and transporting loads, having an upper platform for receiving the loads and block-like or strip-like support elements which are attached to or can be attached to its underside by connecting sections. At least the support elements are made of plastic with fiber material embedded therein. Advantageous shock absorbing properties, along with an advantageous structure, are achieved because the fiber material consists of natural fibers.

7. A pallet for receiving and transporting loads, comprising:
-
an upper platform for receiving the loads and strip-like support elements which are attached to or can be attached to an underside of the upper platform by connecting sections and which are provided with interior hollow spaces, each of the support elements including a counter-connecting section that is inserted into one of the plurality of groove-shaped connecting sections to dispose the supports elements parallel to one another; a lower platform having a top side including a second plurality of groove-shaped connecting sections, and each of the support elements including a second counter-connecting section that is inserted into one of the second plurality of groove-shaped connecting sections of the lower platform; at least the support elements made of a material comprising hemp fibers embedded in a polyurethane foam; the material and a structure of the at least the support elements with the embedded hemp fibers have resilient and damping properties that are matched to weights to be absorbed, wherein the modules of elasticity of the hemp fibers and of the polyurethane foam are matched to each other in a gradual transition for minimizing shear stresses; and hollow spaces produced by shaping in such a way that the strip-like support elements are designed as hollow profiled strips linearly extending between opposing side edges of the upper and lower platforms and whose supporting wall sections between the upper and lower platforms are, at least in a section, curved or inclined in cross section with respect to a horizontal line that is parallel to the upper and lower platforms, wherein the supporting wall cross sections have one of an X-shaped, an S-shaped, a round, or an oval cross-sectional profile structure.
