Carbon Steel U Shaped Box Semi Trailer Dump Truck

As a professional Chinese manufacturer of U-shaped semi-trailers, our carbon steel u shaped box semi trailer dump truck is designed specifically for transporting heavy-duty construction materials. Constructed from high-strength T700 steel, this truck offers 2-5 axle configurations with a load capacity ranging from 30-70 tons, perfectly suited for transporting stone, gravel, sand, coal, and other bulk materials. Equipped with HYVA hydraulic cylinders and a flexible suspension system, it ensures efficient unloading and reliable operation, and can be fully customized to your specific transportation needs.

1. High-Strength T700 Carbon Steel Box - Durable and Wear-Resistant

• The U-shaped box is constructed from T700 high-strength carbon steel, a material renowned for its superior tensile strength (≥700MPa) and impact resistance. Compared to standard carbon steel, it offers the following advantages:

• Improved wear resistance, able to withstand the abrasion from sharp stones and gravel during long-term transportation.

Lighter weight (15% lighter than Q345 steel) while maintaining a 70-ton load capacity, resulting in improved fuel efficiency.

A seamless U-shaped design with full penetration welding eliminates material leakage and structural weak points-crucial for transporting bulk materials such as sand and coal.

2. 2-5 axles & 30-70 ton load capacity - suitable for all transport weight standards

With flexible configurations, our trailers meet a variety of loading needs:

2-3 axles (30-50 tons): Suitable for medium-sized construction sites, urban roads, and narrow work lanes.

4-5 axles (60-70 tons): Designed for large mines and quarries, distributing axle pressure evenly for easy transport of heavy ore and coal.

All models meet global weight standards, ensuring legal operation in domestic and international markets.

3. HYVA Hydraulic Cylinders Enable Efficient Unloading

• The integrated HYVA hydraulic cylinder system enables smooth and controllable rear unloading:

• Rapid tilting ensures complete material slides out without residue-saving cleaning time.

• Built-in overload protection prevents system damage under heavy loads, while the dual-circuit design ensures safe operation even if one line fails.

• Optional heavy-duty hydraulic cylinders are available for conveying ultra-high-density materials such as iron ore, significantly increasing lifting force.

4. Flexible Suspension Systems and Customization Options

• Suspension System Selection: Air suspension systems are suitable for smooth road transport (reducing material shifting), while mechanical suspension systems are suitable for rugged construction terrain (enhancing durability).

• Weather Protection: Optional waterproof tarpaulin covers protect materials from rain and dust, keeping cargo dry and reducing waste.

• Fully Customizable: The number of axles, cargo box size, and cylinder specifications can be customized to your cargo type (e.g., longer cargo boxes for coal, reinforced base plates for sharp gravel).

Our carbon steel U-shaped box semi-trailers excel in the following areas:

• Construction site material transportation (gravel, sand, concrete aggregate)
• Mining operations (coal, ore, stone transportation)
• Quarry and aggregate transportation (crushed stone, limestone)
• Bulk material logistics for infrastructure projects

• Professional Manufacturing: As a professional Chinese manufacturer, we focus on the design of U-shaped semi-trailers, ensuring meticulous attention to every detail.
• Quality Control: Each unit undergoes pressure testing, welding inspection, and load testing before delivery.
• Customization Support: From sample production to bulk orders, we can meet your unique needs-whether for urban construction or mining logistics.
