Key Benefits

What This Unit Does Well

2/3/4 axle configuration provides stable load distribution across heavy container payloads up to 60T
Q345B steel main beams and Q235 side beams offer high strength and durability for long-term use
Mechanical suspension with 10 or 12 leaf springs reduces maintenance and is reliable in rough terrain
12R22.5 tyres from Double Star, Triangle or Linglong are widely available and easy to replace
JOST kingpin ensures secure coupling and compatibility with standard tractor heads
Polyurethane paint finish resists corrosion and maintains appearance in harsh environments

Application Scenarios

Where It Is Used

Transport of 40ft containers between inland depots and seaports on mixed asphalt and gravel roads
Flatbed hauling of heavy machinery and construction equipment across regions with poor road infrastructure
Long-haul container transport where axle load limits require a 3 or 4 axle configuration
Fleet expansion for logistics operators needing a low-maintenance trailer with consistent spare parts availability

Fit

Who It Is For

Fleet owners replacing older trailers with a higher payload and better axle load distribution
Contractors operating in regions with unpaved access roads and high container volume
Logistics companies sourcing trailers with consistent spare parts availability in Africa, the Middle East and Southeast Asia
Dealers stocking semi trailers for resale in markets where container transport is the primary use

Buyer Pain

Problems It Solves

Overloaded axles on 2-axle trailers that cause premature suspension and tyre wear
Lack of spare parts for foreign-branded trailers in remote or developing markets
Inconsistent trailer dimensions and axle configurations that complicate customs and port handling
Poor paint and corrosion resistance leading to early structural degradation in humid or salty environments

Honest Comparison

How It Compares With the Alternatives

2-axle flatbed trailer	The 3/4-axle version handles heavier payloads and reduces axle load per axle, but costs more in initial purchase and maintenance
Air suspension trailer	Mechanical suspension is simpler, cheaper to maintain, and more reliable in dusty or high-temperature environments
ABS not fitted	Without ABS, the trailer is cheaper and easier to service, but lacks anti-lock braking in emergency stops on wet or slippery surfaces

Use Guide

Using It Well

Test the braking system monthly and replace brake chamber seals if air leakage is detected
Keep the twist lock mechanism clean and lubricated to prevent jamming during loading
