High-strength Manganese Steel Fully Enclosed Box-type Rear Tipping Semi-trailer

This is a three-axle fully enclosed box-type rear-tipping semi-trailer, specially designed for the sealed transport of urban construction waste and engineering spoil. It can also transport various bulk materials such as sand, coal, and ore.
 It must be paired with a 6×4 or 8×4 tractor unit to be used on the road. It is compliant and can be registered, fully meeting all domestic requirements for environmentally friendly sealed transport and overloading control.

The cargo box is constructed from high-strength, wear-resistant manganese steel, with a thickened floor plate of 8-10 mm and 6 mm side panels. The interior features reinforced columns and is manufactured using robotic full-welding technology, ensuring it is resistant to bulging, cracking, and deformation even when carrying heavy loads of stones and construction waste.
The fully enclosed, square cargo box structure effectively blocks dust and prevents material spillage during transport, complying with urban construction waste transportation environmental regulations. The rear door is equipped with a hydraulic locking device and sealing strips to prevent leakage and spillage during unloading and driving.
The cargo box length can be customized from 9.5 meters to 13 meters, with a volume ranging from 45 to 70 cubic meters. The lightweight design keeps the vehicle's weight between 7.6 and 8.8 tons, allowing it to carry 30-40 tons of cargo without exceeding weight limits.

Hydraulic Unloading System

Hydraulic Unloading System: Utilizing multiple rear-mounted, thickened hydraulic lifting cylinders and a complete high-pressure hydraulic pipeline system, the maximum lifting angle reaches 52 degrees. The lifting process is smooth and stable, eliminating the risk of tipping or tipping over. The pipeline is equipped with explosion-proof safety valves as standard, ensuring the compartment remains locked even in the event of a pipe breakage during travel or lifting, enhancing safety.
The smooth inner wall of the compartment prevents soil and silt from adhering and remaining during lifting and unloading, resulting in fast unloading speeds and significantly improved site transport efficiency. The entire hydraulic system boasts a low failure rate, making maintenance and replacement simple and convenient.

The chassis features widened and thickened through-type high-strength longitudinal beams, supported by multiple reinforced crossbeams, ensuring fatigue resistance and preventing torsion and breakage under long-term heavy loads. It comes standard with three 13-ton heavy-duty axles, primarily using the Fuwa brand, but can also be upgraded to imported BPW axles; paired with 12R22.5 tubeless steel wire tires, offering wear resistance and strong load-bearing capacity.
The suspension features thickened leaf springs as standard, providing excellent shock absorption and cushioning in complex construction site conditions; optional air suspension further enhances ride stability. The braking system employs a complete air brake structure, equipped with ABS anti-lock braking system, ensuring stable braking during heavy downhill driving and emergency braking, preventing brake slippage and fishtailing, and enhancing safety for daily long-distance transportation.
The sides of the vehicle are equipped with guardrails, reflective markings, and reversing warning lights, ensuring high visibility during nighttime construction site operations.

1. Environmentally friendly, enclosed design ensures dust-free and spill-free transport of construction waste in urban areas, guaranteeing compliance with registration and city entry regulations;

2. Robust manganese steel thickened body structure provides impact and wear resistance, extending the vehicle's service life;

3. Hydraulic rear tipping unloading ensures clean and residue-free unloading, stable and safe lifting, and high efficiency for construction site transport;

4. Lightweight frame with low self-weight and high compliant load capacity, resulting in higher per-trip revenue, fuel savings, and reduced operating costs;

5. Highly compatible parts, allowing for repairs at nationwide service centers, minimizing long-term maintenance costs.

 

Q1: Can you customize trailer sizes and configurations?

A: Yes. All trailers support full customization of length, width, height, number of axles, load capacity, color, and accessories, tailored to the road conditions and cargo requirements of the customer's country.

Q2: What is the maximum load capacity of a trailer?

A: Standard three-axle trailers have a load capacity of 40-60 tons, and can be upgraded to 70-80 ton heavy-duty versions to meet the heavy-duty needs of mines and dirt roads in Africa.

Q3: What material is the trailer beam made of? Is it durable?

A: All beams are made of Q355 high-strength manganese steel, which is harder, more resistant to bumps, and less prone to deformation than ordinary steel, making it ideal for rough roads and mining conditions in Africa.

Q4: What brand of axles do you use?

A: Export standard configuration includes FUWA 13-ton axles, known for their stable quality, globally compatible parts, and convenient after-sales service. BPW axles can also be customized.
