DONGXU Dump Semi-Trailer: High-Efficiency Heavy-Duty, Born for Harsh Working Condition
The DONGXU dump semi-trailer is a high-performance transportation equipment specifically designed for transporting mining, infrastructure, construction waste, and bulk materials. It adopts a high-strength steel welded structure, combined with a front-mounted multi-stage hydraulic lifting system, enabling large-angle, fast, and stable unloading operations. Whether transporting sand and gravel aggregates in the Middle East or heavy-duty short-distance transshipment in African mines, the DONGXU dump semi-trailer maintains reliable operation in high-temperature, dusty, and complex road conditions.
1. High-Strength Box Structure, Durable and Robust
The main body of the box is made of high-strength wear-resistant steel, with targeted reinforcement of the bottom and side plates, making it impact-resistant and wear-resistant, adaptable to frequent loading and unloading of hard materials such as ores, gravel, and slag.
The overall welding process combined with the reinforcing rib design ensures that the box does not deform or crack under heavy-load lifting, significantly extending its service life.
2. Stable and Reliable Hydraulic Lifting System
Equipped with a front-mounted multi-stage hydraulic cylinder, offering high lifting force and a long stroke, with a maximum lifting angle of 45°–50°, ensuring complete unloading of materials without sticking or residue.
Key seals in the hydraulic system are from internationally renowned brands, resistant to high temperatures and aging, ensuring leak-free operation even in the high-temperature environments of the Middle East.
Equipped with a safety hydraulic lock-up valve, it maintains the position of the cargo box even in the event of an unexpected oil cut-off during lifting, eliminating potential safety hazards.
3. Heavy-Duty Chassis and Running Gear
Optional axles from renowned brands such as BPW/FUWA are available, offering strong load-bearing capacity and long maintenance intervals, suitable for long-distance and heavy-duty transportation in mining areas.
Maintains vehicle directional control on slippery roads or during emergency braking, significantly improving driving safety.
Tires can be selected according to target market brands, with specifications including 12.00R20 and 11.00R20, adapting to different road conditions and load requirements.
4. User-friendly design, easy maintenance
The rear of the container features a high-strength hinged door with an automatic locking mechanism, opening automatically during unloading and sealing tightly to prevent leakage when closed.
Key lubrication points are centrally located on the chassis for convenient daily maintenance; easily replaceable parts are readily available in overseas markets.
Optional features include a tarpaulin cover system, side protection, and a rear bumper to meet the regulatory requirements of different countries.
