3 Axle 20ft Container Transport Rear Dumper Semi Trailer

A 3-axle 20ft rear-dumping semi-trailer designed for container transport, with a tare weight of 8000kg and a payload capacity of 30T. Built on a heavy-duty I-beam chassis using high tensile Q345 steel, it features HYVA hydraulic cylinders, FUWA 13T axles, JOST kingpins, and 12R22.5 double-star tires. The trailer is configured for mechanical suspension with leaf springs and includes a WABCO RE6 relay valve braking system, LED lighting, and a 40L air tank. It is suitable for rugged terrain and long-haul container movement where reliable dumping and axle strength are required.

Key Benefits

What This Unit Does Well

30T payload capacity on a 3-axle layout ensures compliance with weight limits on most international routes
Q345 high tensile steel chassis with automatic submerged-arc welding improves structural integrity and fatigue resistance
HYVA hydraulic cylinders provide consistent and reliable rear dumping performance under heavy loads
FUWA 13T axles are widely available in export markets, reducing spare parts lead time
12R22.5 double-star tires offer good load capacity and durability on mixed road surfaces
JOST kingpin and landing gear provide secure coupling and stable support during loading and unloading

Application Scenarios

Where It Is Used

Container transport between inland depots and seaports on roads with moderate to poor surface quality
Dumping of bulk materials at construction sites with limited access and uneven ground
Long-distance haulage of 20ft containers where axle load distribution must be controlled
Operations in regions with high humidity or salt exposure where corrosion resistance is critical

Fit

Who It Is For

Fleet operators sourcing trailers for container transport in Africa, the Middle East, or Southeast Asia
Contractors needing a rear-dumper trailer for material delivery to remote or off-road sites
Machinery dealers stocking semi-trailers for resale in markets with high demand for dump trailers
Logistics companies standardizing on a single trailer type with shared parts across their fleet

Buyer Pain

Problems It Solves

Overloading on single axles due to poor weight distribution in multi-axle trailers
Downtime caused by hydraulic cylinder failure or weak chassis in high-stress transport
Difficulty finding spare parts for non-standard or obscure trailer brands
Inconsistent dumping performance due to weak or outdated hydraulic systems
Lack of corrosion protection in trailers shipped to coastal or humid climates

Process

How an Order Is Handled

You provide the route, payload, and terrain conditions you expect the trailer to operate in
We confirm the chassis, axle, and suspension configuration based on current stock or production schedule
You approve the final specification sheet, including color, tire brand, and accessory list
The trailer is built, inspected, and photographed before loading
We arrange RoRo or container shipment and issue export documents including commercial invoice, packing list, and certificate of origin

Quality Control

Checks Before Loading

Chassis and axle numbers are photographed and matched to the approved specification
Hydraulic cylinder function and dumping cycle are tested and recorded on video
Paint, glass, and structural welds are inspected for damage before loading
Loading and lashing photos are sent before the vessel departs

Customisation

What Can Be Changed

Color other than standard white or grey
Tire brand and size change (within 12R22.5 range)
Additional tool box or spare tire carrier
ABS system installation as an option
Modified landing gear height or manual override for specific site access

Honest Comparison

How It Compares With the Alternatives

2-axle 20ft container trailer	The 3-axle version handles heavier payloads and better distributes weight on poor roads, but has higher purchase and maintenance cost
Front-dump semi trailer	Rear-dump allows for better load control during unloading and avoids spillage on uneven ground, but requires more space to turn
Aluminum trailer	Steel construction is more durable and cheaper to maintain, but heavier than aluminum alternatives

Use Guide

Using It Well

Inspect hydraulic cylinder seals and fluid level before first use and refill if needed
Clean and lubricate the landing gear mechanism every 3 months to prevent seizing
Replace air dryer desiccant cartridge annually or after exposure to high humidity
Use only approved hydraulic fluid for the HYVA system to avoid seal damage
