Abstract: The authors develop a new concept of dump trailer vehicle designed to carry arid materials, with a series of advantages and improvements with regard to equivalent structures. For this reason, design criteria and objectives that must have been carried out in executing different stages to reach the final 'optimum' vehicle have been taken into account. From a detailed study of previous performances for this type of vehicle, it is intended to reach a series of objectives involving redesign and modification. The structural lightening and changes must mean the improvement of structural performances, both in terms of rigidity and endurance. The improvement of these variables will make possible the launch of a new product incorporating an improvement over current models. Moreover, the inclusion of sandwich structures in the design of the dump box's floor and door supposes a great novelty, intended to achieve significant weight saving.
