The core advantages of U-shaped rear-dump trucks

The U-shaped dump truck has become a core tool in the field of engineering transportation due to structural optimization, performance improvement, and environmental adaptability. Its core advantages are reflected in four aspects: structural lightweighting and strength improvement, unloading efficiency and cleanliness optimization, driving stability and safety enhancement, and durability and impact resistance improvement

1、 Lightweight structure and strength improvement
The U-shaped cargo box subverts the traditional square cargo box model that relies on thickened box plates and frame structures to enhance strength through system structure design. It uses high-strength steel plates (such as domestically produced high-grade steel or imported steel from Sweden), which reduces the thickness of the plates by about 20% and reduces the weight by more than 1 ton while ensuring the strength of the cargo box. This weight reduction design significantly improves the utilization coefficient of load capacity, allowing vehicles to transport more goods under the same load, while reducing fuel consumption and improving economic efficiency.

2、 Optimization of unloading efficiency and cleanliness
Streamlined design: There are no dead corners inside the U-shaped cargo box, and the corners adopt curved transitions, which makes it less likely to stick to the box during unloading, and the residual rate is basically zero. This feature is particularly prominent when transporting loose materials such as sand, gravel, and ores, avoiding the trouble of manual cleaning after unloading traditional square cargo boxes and greatly reducing unloading time.
Curved bottom plate: The U-shaped bottom plate reduces the hard collision between ore and other goods and the bottom plate, reduces the risk of container deformation, and avoids cargo jamming, making the unloading process smoother.
3、 Enhanced driving stability and safety
Center of gravity reduction: The bottom of the U-shaped cargo box has removed the frame structure of the square cargo box and is designed in an arc shape with a lower center of gravity. This improvement makes the vehicle travel more smoothly, especially when cornering, effectively preventing cargo from falling and improving driving safety.
Uniform tire stress: The U-shaped cargo box can keep the goods centered, ensuring even stress on both sides of the tires, extending tire life, and reducing safety hazards caused by uneven tire wear.
4、 Improvement of durability and impact resistance
Application of high-strength steel plates: The high-strength steel plates used in U-shaped cargo boxes have high yield strength, better impact resistance, and fatigue resistance. For the scenario of transporting sharp edged goods such as ore, this material can effectively reduce the damage of goods to the cargo box and extend the service life of the cargo box.
Flexible bottom plate structure: The curved design of the U-shaped bottom plate can dissipate some of the impact force when the ore falls, preventing the bottom plate from deforming. This feature is particularly important in harsh working conditions such as mines, as it can significantly reduce the frequency and cost of container maintenance.
