Lining, a haul truck body comprising the same and a haul truck

1. A lining for a haul truck body, said lining being arranged to extend over surfaces of said haul truck body, wherein said surfaces define at least one impact region and at least one wear region;

wherein said lining within said at least one impact region presents a plurality of impact lining elements;

wherein said lining within said at least one wear region presents a plurality of wear lining elements; and

wherein the plurality of impact lining elements and the plurality of wear lining elements each comprise rubber or polyurethane;

wherein said impact lining elements have a higher impact resistance than said wear lining elements and said wear lining elements have a higher wear resistance than the impact lining elements.

2. The lining according to claim 1 , wherein the at least one impact region comprises a loading region extending over a part of a bottom surface of the haul truck body, wherein the at least one wear region comprises a tipping region extending over another part of the bottom surface of the haul truck body, and wherein the loading region is arranged in front of the tipping region.

3. The lining according to claim 2 , wherein the tipping region extends to a rear end of the bottom surface of the haul truck body.

4. The lining according to claim 2 , wherein the loading region extends forwardly from a center of the bottom surface of the haul truck body.

5. The lining according to claim 2 , wherein the at least one impact region further comprises a further loading region extending over at least a part of a front surface of the haul truck body.

6. The lining according to claim 1 , wherein the impact lining elements and the wear elements comprise different materials.

7. The lining according to claim 1 , wherein the impact lining elements and/or the wear lining elements comprise one or more from rubber, polyurethane, ceramics and metallic alloys.

8. The lining according to claim 1 , wherein the impact lining elements have a Young's modulus lower than a Young's modulus of the wear lining elements.

9. The lining according to claim 1 , wherein the wear lining elements comprise one or more wear-resistant portions at least partly embedded within the wear lining elements and distributed over at least a part of an outwardly directed surface of the wear lining elements, such that the one or more wear-resistant portions are arranged to make contact with material present in said haul truck body.

10. The lining according to claim 9 , wherein the one or more wear-resistant portions comprise a ceramic material and/or a metallic alloy.

11. The lining according to claim 10 , wherein the wear lining elements comprise a wear layer facing the inside of the haul truck body and a mounting layer facing surfaces of the haul truck body, and wherein the wear layer comprises the one or more wear-resistant portions.

12. The lining according to claim 11 , wherein said plurality of impact lining elements are arranged adjacent to each other such as together to form one or more areas of substantially uniform impact resistance, and wherein said plurality of wear lining elements are arranged adjacent to each other such as together to form areas of substantially uniform wear properties.

13. The lining according to claim 1 , wherein the lining is formed by a plurality of lining elements further comprising a first type of lining elements, termed load-breaking lining elements, and a second type of lining elements, different from the load-breaking lining elements, said load-breaking lining elements being structured and arranged to restrict, to a higher degree than the second type of lining elements, load movement in relation to the lining.

14. A haul truck body comprising a lining according to claim 1 .

15. A truck comprising a haul truck body according to claim 14 .
