Wear resistant lining element and method for disengaging material

The invention relates to a wear-resistant lining element (3) which is intended for a surface (4) on a truck haul body (1) subjected to wear. The wear-resistant lining element (3) has an outwardly directed surface (6), over which material in the form of pieces or particles, such as crushed ore and crushed rock material, is intended to move, and has an inwardly directed surface (7) intended to face the truck haul body surface (4). The wear-resistant lining element (3) comprises elastomeric material. The wear-resistant lining element (3) is characterized in that the wear-resistant lining element (3) comprises at least one open cavity (8) in the inwardly directed surface (7). The invention also relates to a wear-resistant lining (2), a truck haul body (1) and a method for disengaging material adherent on a truck haul body surface (4) having a wear-resistant lining (2).
