1. A pallet for carrying load, comprising: a load carrying part and at least one beam, the load carrying part comprising: an upper surface configured to carry a load; anda bottom surface; andthe at least one beam, being distinct from said load carrying part, and extending laterally below the bottom surface of said load carrying part, the beam consisting of a laterally extending force carrying element having a first lateral end and a second lateral end and a tension element, the tension element extending from said first lateral end to said second lateral end below said force carrying element, the tension element downwardly curving said force carrying element thereby to cause downward bowing of said force carrying element between said first lateral end and said second lateral end to maintain a tension of said force-carrying element. 2. A pallet according to claim 1, wherein said tension element is attached along the length of the force carrying element for maintaining said curvature of the force carrying element. 3. A pallet according to claim 2, wherein the force carrying element is prestressed before attaching the tension element to the force carrying element. 4. A pallet according to claim 3, wherein the tension element comprises one member of the group consisting of a cable attached to a hook and wherein the cable is stressed by rotating the hook, a cable and turnbuckle and wherein the cable is stressed by rotating the turnbuckle, and a cable that is shorter than the force-carrying element, and/or where the force-carrying element comprises one member of the group consisting of a flat element, an element in the form of a curved arch, and an element in the form of a cross-section of a dome. 5. A pallet according to claim 2, wherein the beam is prestressed by stressing the tension element. 6. A pallet according to claim 5, wherein the tension element is stressed to between 50-200 kg tensile strength. 7. A pallet according to claim 1, wherein at least three equally distanced beams are attached to the bottom surface of the pallet. 8. A pallet according to claim 1, wherein the pallet when racked is adapted to carry between 120-200 kg of load for each 1 kg of raw material of the pallet. 9. A pallet according to claim 1, wherein the beam is one member of the group consisting of being integrally formed with said pallet, and being removably attached to said pallet. 10. The pallet of claim 1, wherein said at least one beam comprises two beams diagonally attached. 11. A beam for directly attaching to a load, the beam comprising: first and second support elements adapted to be attached to a strap of the load; anda force carrying element extending lengthwise between the first and second support elements respectively, the force carrying element having a first lateral end and a second lateral end, an upper side towards said load and a lower side away from said load, and a tension element, the tension element extending from said first lateral end to said second lateral end on said lower side to curve said force carrying element in a direction of said lower side, thereby to maintain a tension of said force-carrying element. 12. A load according to claim 11, wherein the support elements comprise a recess for receiving the strap of the load. 13. A load according to claim 12, wherein the strap of the load comprises a dent at the point of attachment to the recess of the support element. 14. A beam according to claim 11, wherein said tension element preserves a stress of the force carrying element. 15. A beam according to claim 14, wherein the tension element comprises at least one cable connected between two ends of the force carrying element, or wherein the tension element is stressed to between 50-200 kg tensile strength. 16. A pallet according to claim 14, wherein the beam is prestressed before attaching the tension element. 17. A beam according to claim 11, wherein the force carrying element is in the form of one member of the group consisting of a curved arch and a triangular truss. 18. A beam according to claim 11, wherein the beam is adapted to carry between 120-200 kg of load for each 1 kg of raw material of the beam. 19. A method of attaching a strap to a beam to secure a load, the method comprising: providing a load;providing a strap;providing at least one beam for supporting the load, the beam having a first lateral end and a second lateral end and an upper side and a lower side;providing a cable on a lower side of said beam between said first lateral end and said second lateral end to curve said beam in a direction of said lower side between said first lateral end and said second lateral end, thereby to maintain a tension in said beam, the tension being towards said lower side;placing the load on said upper side of the beam opposite said tensioned side; andclosing the strap over the load between ends of the beam thereby attaching the load to the curved beam, the cable causing said curving to be retained. 20. A method according to claim 19, wherein providing the tension cable comprises tightening the tension cable, thereby stressing the beam.
