3 Axle Fence Semi Trailer

This 3-axle fence semi-trailer is designed for high-intensity logistics, engineered to transport bulk cargo, steel products, industrial machinery, and agricultural goods. By integrating a reinforced heavy-duty chassis with a modular fence structure, this trailer provides the structural rigidity required for high-payload operations while maintaining the operational flexibility necessary for diverse loading/unloading environments.

Heavy-Duty Chassis Architecture
Material Specification: Constructed from Q345B high-strength low-alloy steel. Main beam flange and web thicknesses are customized (ranging from 14mm to 20mm) based on payload requirements (30T–80T) to optimize the strength-to-weight ratio.
Precision Welding: The frame is manufactured using submerged arc welding (SAW) with CO2 shielding. All primary load-bearing welds undergo ultrasonic non-destructive testing (NDT) to prevent fatigue cracking, ensuring the frame maintains structural integrity under sustained vibration and heavy-load conditions.
Corrosion Protection: The chassis undergoes rigorous sandblasting to an SA2.5 standard, followed by a double-layer anti-corrosive primer and a high-durability polyurethane finish to maximize service life in harsh climates.

Modular Fence & Cargo System
Design Versatility: Fence sidewalls are available in plug-in or welded configurations. Heights are fully customizable between 800mm and 1200mm to match specific cargo volume and stacking requirements.
Operational Efficiency: Equipped with heavy-duty, quick-release locking mechanisms for efficient side-loading via forklift. Post-and-rail spacing is engineered to ensure optimal cargo containment while allowing the ventilation required for agricultural products.
Load Platform: Features a 3mm industrial-grade anti-slip diamond steel plate, providing high friction to prevent cargo shifting during long-distance transit.
 

Running Gear & Safety Systems
Axle Reliability: Features internationally recognized axle brands, such as FUWA or BPW. Axle centers are calibrated at 1310mm to ensure optimal load distribution, reducing tire scrubbing and maintenance costs.
Suspension Options: Available with heavy-duty mechanical leaf-spring suspension for rugged, off-road terrain or pneumatic air suspension for high-value, vibration-sensitive cargo. Air suspension systems offer automatic height adjustment and superior damping.
Braking & Control: Equipped with a dual-circuit pneumatic braking system compatible with WABCO components, featuring an integrated ABS (Anti-lock Braking System) to ensure vehicle stability during emergency stops and extended descents.

Steel Logistics: Optimized for steel pipes, coils, and rebar, with a reinforced frame designed for concentrated point loads.
Agricultural Transport: Flexible sidewalls allow for the bulk transport of grain, fertilizer, and heavy-duty agricultural equipment.
Industrial Machinery: The heavy-duty chassis provides the stability required for oversized industrial components and factory equipment.
General Freight: The open-deck design offers versatility for logistics companies managing mixed cargo profiles.

Rigorous Validation: Every unit undergoes dynamic load testing and brake pressure calibration before delivery to ensure structural integrity and compliance with road safety standards.
Regional Compliance: We collaborate with fleet operators to calibrate axle load distribution and dimensional specifications to meet the specific road-traffic regulations of your target market (e.g., Southeast Asia, Africa, Middle East).
Consultative Customization: From tire selection and suspension types to side-gate configurations, we provide engineering support to match your operational budget and maintenance capabilities.
