A folded hopper for a mining truck, having a floor made of an anti-abrasive material that increases its resistance and simplifies manufacturing work, bringing up substantial savings of welding and being of low weight, and improving load distribution. The floor includes floor folds with anti-abrasive, side folding that eliminates welding at joints and floor, which improves mechanical resistance and eliminates stress arising from heat concentration upon welding. At the sides, the reinforcement on several beams is simplified by two larger joining beams that keep the structure rigid. |
