Core Advantages
1. Heavy-Duty & Wear-Resistant Structure
The cargo body is constructed from high-strength, abrasion-resistant steel (HARDOX 450/500), providing exceptional durability against the impact and friction of sharp materials like stone and ore. The U-shaped design eliminates material buildup and dead corners, ensuring complete discharge. The reinforced chassis and crossbeams prevent deformation under extreme torsion and heavy loads.
2. Efficient Hydraulic Tipping System
Equipped with a powerful front-mounted hydraulic cylinder, the trailer achieves a large tipping angle (45-55°), ensuring fast and complete unloading of bulk cargo. The hydraulic system features safety valves and emergency stop functions, guaranteeing stable and secure operation even on uneven ground.
3. Superior Safety & Stability
The low center of gravity design, combined with a wide axle track, significantly enhances stability during transportation and tipping, reducing the risk of rollover. The advanced WABCO braking system with ABS ensures reliable and responsive braking, even when fully loaded on steep downhill sections.
4. Versatile Application & Efficiency
The rear dump design is ideal for transporting and unloading a wide variety of bulk materials. It eliminates the need for additional unloading equipment, drastically improving operational efficiency at construction sites, mines, and quarries. The design allows for easy loading from the top using loaders or excavators.
5. Global Compliance & Customization
Fully compliant with international transport standards, it can be customized to meet specific regional regulations and operational requirements. Options include different body styles (U-shaped/rectangular), tailgate types (hinged/clam shell), and additional features such as tarpaulin covers, side bumpers, and toolboxes.
Application Fields
Ideal for transporting and unloading various bulk materials, including:
- Construction Materials: Sand, gravel, crushed stone, asphalt, and construction waste.
- Mining Products: Coal, ore, and mineral aggregates.
- Agricultural Goods: Grain, feed, and fertilizer.
- Earthmoving Projects: Soil, clay, and other excavation materials.
- Widely used in road construction, building projects, mining operations, and large-scale earthmoving projects, serving industries such as construction, mining, agriculture, and infrastructure development.
Frequently Asked Questions (FAQ)
What is the maximum payload of the rear-dump semi-trailer?
Answer: The payload capacity ranges from 30 to 80 tons, depending on the axle configuration (3-4 axles) and regional transport regulations.
What is the difference between U-shaped and rectangular body styles?
Answer: The U-shaped body features a rounded bottom, which prevents material from sticking and ensures complete, clean unloading. It is lighter and more efficient for most bulk materials. The rectangular body offers a larger internal volume and higher structural rigidity, suitable for extremely heavy or dense materials.
Is the hydraulic system safe?
Answer: Yes. The system is equipped with multiple safety features, including hydraulic lock valves to prevent accidental lowering, overload protection, and an emergency stop button, ensuring maximum operational safety.
Can it be used for long-distance transport?
Answer: Yes. The robust chassis and reliable suspension system ensure stability and durability for long-haul journeys. An optional tarpaulin cover is recommended to prevent material spillage and dust pollution on public roads.
What maintenance is required for the hydraulic system?
Answer: Regular maintenance includes checking hydraulic oil levels, replacing filters, inspecting hoses for leaks or damage, and lubricating moving parts to ensure smooth and reliable operation of the tipping mechanism.
Is it compatible with standard tractors?
Answer: Yes, it fits most tractors equipped with ISO-standard 2.0/3.5 inch kingpin connections. For the hydraulic system, a power take-off (PTO) on the tractor is required.
