  "description_excerpt": "The disclosure relates to a lining for a haul truck body and a transition lining element for use in a haul truck body. The disclosure further relates to a method for fastening a lining for a haul truck body.\n\nHaul trucks are off-highway dump trucks engineered for use in high-production mining and heavy-duty construction environments. The haul trucks are equipped with haul truck bodies capable of accommodating a large amount of material, such as rock, crushed ore or the like. Haul truck capacities range from 40 short tons (36 t) to 496 short tons. Hauling such masses of often sharp and heavy load makes the haul truck body experiencing a heavy wear due to impact and abrasion.\n\nTo protect the surface of the haul truck body, it is common to equip the interior if the haul truck body with a lining. Whereas the haul truck body usually is made from steel, the lining material is often made from another material. One commonly used type of lining is an elastic lining comprising for example a rubber material or polyurethane. An advantage of the elastic lining material is that its material properties may be used to mitigate the effects of heavy impact of material on the haul truck body as material is hauled from quite some altitude onto the haul truck body from for example an excavator. The elastic lining material effectively absorbs the energy from the impact distributing said energy over a larger area. Moreover, the noise is reduced and the comfort for the operator improved. Lining for haul trucks are usually made from a plurality of lining elements extending over surfaces of the haul truck body to form the lining.",
