1. Overview

The 3-Axle Fence Type Semi-Trailer is a versatile transport solution designed for bulk cargo, palletized goods, and construction materials. Unlike a flatbed, it provides better lateral protection for your cargo; unlike a box van, it offers much higher loading/unloading efficiency.

Built with a robust fence structure and high-strength steel chassis, this trailer achieves the perfect balance between lightweight design and heavy load capacity. Whether transporting bagged grain, construction bricks, timber, or industrial pallets, this 3-axle trailer delivers safe, compliant, and efficient performance.

2. Key Features

• Modular Fence Design
  Removable / foldable side fences. For oversized cargo (e.g., heavy machinery), fences can be quickly flattened or removed – instantly converting the trailer into flatbed mode.

• 3-Axle Suspension Options (Mechanical or Air)
  Standard mechanical suspension (leaf spring) or optional air suspension. Air suspension significantly reduces cargo vibration, protects fragile goods, and improves ride quality when empty.

• High Load Capacity
  Main beam made of Q345B high-strength manganese steel with a through-type design for even load distribution. 3 axles (typically 13T–16T per axle) support a total GVW of up to 40+ tons.

• Superior Braking System
  Full vehicle equipped with WABCO valves (or high-end domestic alternatives) + dual-circuit braking. Optional EBS (Electronic Braking System) shortens stopping distance and prevents trailer jackknifing.

• Corrosion Protection
  Full shot blasting to Sa2.5 level, plus dual coats of primer and top paint. Durable and suitable for coastal or high-humidity environments.

4. Applications

• Construction Materials: Bricks, cement bags, sand/gravel bags, aerated blocks. Fences prevent small particles from spilling during turns.

• Forestry & Agriculture: Logs, square timber, straw bales (requires fence extensions).

• Palletized Goods: Depot-to-terminal pallet transport with side forklift access – no need to climb into the trailer.

• Recycling Industry: Scrap metal, baled waste paper, plastic bottle bales.

• Special Modifications: Add a tarpaulin roof for rain/sun protection when transporting grain or fertilizer.

6. Buying Guide

To ensure you get the most suitable trailer, please provide the following information:

1. Tractor Type:
   Tell us your fifth wheel height and tractor horsepower. This determines front overhang matching.

2. Main Cargo & Weight:

   • Heavy duty (>50T) → Recommend 16T axles + reinforced springs.

   • Standard load (~40T) → Recommend 13–15T axles + lightweight design (fuel-saving).

   • Fragile items (tiles, electronics) → Must choose air suspension.

3. Local Regulations:

   • Provide your region's L×W×H limits (e.g., Europe allows 16.5m total length, China limits 13m).

   • Is EBS mandatory? Need ADR (hazardous goods) certification?

4. Environment:

   • Coastal areas → Strongly recommend extra anti-corrosion treatment.

   • Mining areas → Add underfloor protection and heavy-duty mud flaps.
