The curtain sider semi - trailer is expertly crafted to meet the demands of modern freight transportation.
1. Design and Structural Features
• Lightweight Design: Employing an innovative lightweight design philosophy, every component is carefully engineered to reduce overall weight without sacrificing strength. This is achieved through a combination of material optimization and intelligent structural design. For instance, the frame is made from high - grade steel that undergoes a unique tempering process, enhancing its strength - to - weight ratio.
• Hybrid Material Construction: It features a steel - aluminum hybrid construction. The main load - bearing parts like the frame are constructed from high - strength steel, while components such as the curtain system skeleton, side and rear protection, toolboxes, and air reservoirs are made of lightweight yet durable aluminum alloy. This not only reduces the vehicle's weight but also improves corrosion resistance.
2. High - Quality Components
• Axles: Equipped with 10 - ton - class SAF integrated axles, which are renowned for their reliability and load - bearing capacity. These axles are designed to handle heavy loads with ease, ensuring a smooth and stable journey even on rough terrains.
• Coupling and Support: The JOST brand 50 - type tow pin offers a secure and efficient connection to the tractor. Complemented by the AC400 linkage support legs, they provide stable support during loading and unloading operations, guaranteeing the safety and stability of the semi - trailer.
• Special - Purpose Lubricants and Hoses: The axles are filled with low - temperature - resistant lubricant, enabling smooth operation in cold climates. The air - supply hoses can withstand temperatures as low as - 40°C, ensuring the braking system functions flawlessly in extreme cold.
3. Suspension and Lighting Systems
• Air Suspension: The air - suspension system is a highlight of this trailer. It provides excellent stability, reducing the impact of road irregularities on the cargo. By adjusting the air pressure, the trailer can be easily matched with different tractors, and it also offers better shock absorption, which is crucial for protecting sensitive goods.
• LED Lighting: The entire vehicle is outfitted with energy - efficient LED lighting. The fully - enclosed waterproof combination taillights ensure high - visibility in all weather conditions. Their low - power consumption not only saves energy but also contributes to the overall cost - effectiveness of the trailer.
4. Loading and Unloading Advantages
• Operational Simplicity: Unlike common van trucks and container semi - trailers, this curtain sider semi - trailer is designed for easy operation. It can be opened from both sides and the rear, allowing for convenient loading and unloading. This design feature enables simultaneous side - loading and unloading, eliminating the need to worry about the vehicle's parking orientation.
• Versatile Cargo Handling: It is highly suitable for transporting palletized goods, as well as various types of bulk cargo that require protection. The lightweight and easy - to - operate curtain system makes the process of accessing and securing the cargo quick and efficient.
5. Application and Market Reach
• Transportation Economy: With its lightweight design and efficient operation, the curtain sider semi - trailer offers good transportation economy. It can carry a significant amount of cargo while consuming less fuel, making it an attractive option for freight companies.
• Export - Oriented: This semi - trailer has been well - received in international markets and is regularly exported to countries in Europe, America, and other regions. It meets international quality and safety standards, ensuring seamless integration into global transportation networks.
