The three-axle dump semi-trailer is a commonly used special vehicle for heavy transportation. It has a stronger load capacity and better mobility compared to the traditional two-axle semi-trailer. This type of semi-trailer finds wide applications in construction, mining, and agriculture.

The three-axle dump semi-trailer typically consists of two main parts: the front section for traction and steering, and the three-axle dump semi-trailer car responsible for loading and dumping. This design significantly increases the vehicle's load capacity, typically reaching a total mass of 30-50 tons. The carriage is constructed with durable, all-metal welding to enhance durability and impact resistance. The dump mechanism is powered by hydraulic cylinders to enable fast and efficient dumping. Additionally, the carriage is reversible, making it convenient for loading and unloading various bulk materials.

Dump trailer advantages: 
1. Excellent stability: The four-axle design provides excellent stability, especially in harsh road conditions. 
2. Strong carrying capacity: It can easily handle a large number of goods and improve transportation efficiency. 
3. Excellent durability: The use of high-strength materials and advanced manufacturing technology ensures the long-term stable operation of the semi-trailer. 
4. Versatility: Suitable for all kinds of goods, from building materials to ores, with a wide range of uses.
