Abstract
A hopper for transportation of mineral or aggregates which prevents the material from falling off due to movements or slope, and which improves load performance and facilitates the download. In the joining areas between the front and the floor and between the sides and the floor there are folded or cylindered pieces giving curvature to such joining points, thus adding anti-adherent features to this hopper. The front is folded with a wide radius, also achieving an anti-adherent feature. There are also folds in the front and the shield to avoid beams in those areas of the hopper, thus decreasing the total weight of such hopper and reducing the appearance of cracks and lessening the amount of welding. Additionally, the area of release is wider than the front and shield portions to allow for a better sliding of the material during unloading.
