Key Benefits

What This Unit Does Well

  • 16Mn steel space frame chassis provides high bending and deformation resistance for heavy payloads
  • Three axles allow even weight distribution across the trailer, reducing axle overload risk
  • Mechanical or air suspension options suit both rough terrain and smooth highway operations
  • 12500mm platform length fits standard 40ft containers and large industrial equipment
  • Dual-circuit air brakes with quick release valves improve stopping safety on loaded and empty runs
  • Pre-treated chassis with shot blasting and anti-corrosive primer ensures paint adhesion and long-term rust resistance
Application Scenarios

Where It Is Used

  • Transport of heavy machinery and industrial equipment across unpaved construction sites in Africa and Southeast Asia
  • Flatbed hauling of prefabricated steel structures or mining equipment on long-distance routes with poor road surfaces
  • Container transport on routes where port access roads are ungraded and require high ground clearance
  • Bulk material movement in oil and gas fields where trailers must carry 40+ tonnes over uneven terrain
Fit

Who It Is For

  • Fleet operators managing heavy hauls in emerging markets with limited road infrastructure
  • Contractors transporting large industrial components where trailer strength and payload are critical
  • Machinery dealers stocking semi-trailers for resale in regions with high demand for rugged flatbeds
  • Government procurement teams sourcing durable trailers for engineering and infrastructure projects
Buyer Pain

Problems It Solves

  • Trailer frame failure under heavy loads due to weak or undersized chassis construction
  • Excessive axle wear and suspension failure on rough roads due to low-impact resistance design
  • Inconsistent payload capacity across trailers due to non-standard axle and beam configurations
  • Delayed operations caused by brake system failure on long hauls without reliable service access
  • Corrosion damage during sea transport due to poor surface preparation and paint adhesion
Engineering

Technical Features

  • High-strength 16Mn steel space frame chassis with automatic submerged arc welding
  • Longitudinal beams and cross members welded from hot-rolled structural steel
  • Three axles from FUWA, BPW, HJ, L1, FUHE or YORK, rated for 13T each
  • Mechanical suspension or air bag suspension with patented rod connecting design
  • Dual-circuit air brake system with quick release valve and KTL valve
  • Optional ABS system with WEBCO brake components
  • 2" (50mm) or 3.5" (90mm) king pin for compatibility with various tractor heads
  • LED lighting system with 24V voltage and 7-way receptacle
  • Waterproof detachable tool box with large storage capacity
  • Chassis treated with sand blasting, one coat of anti-corrosive primer, two coats of final paint

Honest Comparison

How It Compares With the Alternatives

2-axle flatbed trailerThe 3-axle design supports higher payloads and better weight distribution but increases purchase cost and fuel consumption
Air suspension onlyMechanical suspension is lower cost and easier to maintain in remote areas without repair facilities
Use Guide

Using It Well

  • Check brake air pressure and line integrity before every long haul
  • Keep the tool box dry and secure to prevent loss during transport
  • Use only approved brake fluid and follow the manufacturer's maintenance schedule

Buyer Questions

Questions About This Unit

Is this trailer new or used

All trailers are new. We supply only units built to order or from current stock, with full documentation and factory inspection records.

What is the lead time

Trailer preparation and shipment depend on axle and suspension availability. We confirm a lead time in writing with the proforma invoice.

Can you supply spare parts later

Yes. We supply axle components, brake parts, tyres, and suspension kits separately. These can be consolidated with your trailer order or shipped later.

Do you ship by container or RoRo

RoRo is standard for flatbed trailers. Container shipment is possible but requires lowering the cab and may affect loading access.

What documents do I get for customs

Commercial invoice, packing list, bill of lading, certificate of origin, and any pre-shipment inspection certificate your country requires.

Can I inspect the trailer before paying the balance

Yes. You can appoint SGS, BV or your own agent to inspect the trailer at the yard before loading. We will arrange access upon your request.
