Focusing on heavy-duty transport demands, this model achieves a perfect balance of ultra-large payload, stable driving performance and flexible turning performance. It supports full customization of vehicle size, fence structure and core configurations, with multiple structural versions to adapt to different road limit regulations and cargo types. Matched with brand heavy-duty axles, optional air suspension and mature dual-line safety braking system, the trailer delivers strong load-bearing capacity, excellent road adaptability and low failure rate, greatly improving heavy-cargo transportation efficiency and comprehensive fleet benefits.

Key Features

• Ultra-Large Payload & Heavy-Duty Bearing Capacity
  Specially built for heavy-haul logistics, the trailer supports a rated payload of 30–80 tons, far exceeding the load limit of medium-load semi-trailers. With upgraded thickened main beam structure and reinforced overall rigidity, it can stably cope with long-term full-load and overloaded transportation tasks. It features outstanding driving stability and turning flexibility, being the most popular mainstream model for daily heavy-cargo transportation of global logistics companies.
• Upgraded Reinforced Frame & Anti-Fatigue Structure
  The whole frame is optimized for heavy-load working conditions. The 500mm height main beam adopts 16mm/10mm/18mm thickened three-section plate structure, which greatly enhances bending resistance and impact resistance. Standard Q345B carbon steel ensures stable basic performance, while optional T700 high-strength steel and aluminum alloy accessories realize lightweight optimization without reducing bearing capacity. The 16mm Q235B channel steel side beam and 3mm anti-slip checkered steel floor further strengthen overall structural firmness.
• Full-Scene Customization for Size & Structure
  It supports flexible customization of trailer length, width and fence height (600mm–1700mm adjustable) to prevent cargo spillage and falling during bumpy transportation. Three structural schemes are available: standard type, lightweight type and heavy-duty reinforced type, which can scientifically match local road weight limit standards and customer cargo characteristics. Optional segmented opening and hydraulic flipping fence structures greatly improve the efficiency of bulk cargo loading and unloading.
• Premium Matching Configuration & Stable Safety Performance
  Equipped with 3 pieces of 13T/16T heavy-duty axles (FUWA/BPW optional) to meet ultra-heavy load transport demands. The standard export 10-layer leaf spring suspension adapts to complex rough road conditions, while upgraded air suspension provides superior shock absorption, suitable for fragile goods and livestock transportation. The dual-line pneumatic brake system with WABCO relay valve ensures sensitive and stable braking under full-load status. The full LED electrical system complies with international road safety standards to guarantee all-weather driving safety.
• Strict Anti-Corrosion Process & Long Service Life
  Every trailer undergoes standardized professional anti-corrosion treatment including sand blasting rust removal, anti-corrosive primer and polyurethane finish paint, with customizable body colors. Fitted with reliable JOST brand kingpin and 28-ton two-speed manual landing gear to ensure stable vehicle connection and parking. Optional ABS anti-lock system and container twist locks enrich functional scenarios, while standardized whole-vehicle accessories simplify daily maintenance and replacement.

Specifications

Application Scope

• Heavy Bulk Commodity Transportation
  Suitable for large-volume and heavy-weight bulk cargo such as grain, fertilizer, feed, timber and bagged industrial materials. The height-adjustable fence structure effectively encloses loose goods, preventing leakage and damage during long-distance and bumpy transportation.
• Livestock & Fresh Cargo Transportation
  The open fence design with customizable spacing ensures good internal ventilation, perfectly meeting the transportation demands of poultry, livestock and other live goods. The optional air suspension reduces body vibration and protects the safety of live cargo during transit.
• Construction & Engineering Materials Transport
  With super strong load-bearing capacity, it is applicable for heavy construction materials, mechanical accessories and bulk engineering supplies. The reinforced floor and fence structure resist impact and friction, adapting to harsh construction logistics scenarios.
• Long-Distance Intercity Highway Logistics
  Stable three-axle load distribution ensures high-speed driving stability, suitable for cross-region and long-distance heavy-load freight. It solves the pain points of insufficient load capacity and poor stability of medium-load trailers, maximizing single-trip freight volume and economic benefits.

FAQ

• What is the legal maximum gross weight and cargo capacity of the 3-axle fence semi-trailer?
  The maximum legal gross vehicle weight shall comply with local road transport regulations. The actual available cargo capacity equals the gross weight limit minus the trailer tare weight. Overloading is strictly prohibited. We can optimize the vehicle structure and configuration according to your conventional cargo weight and transport scenarios.
• What are the differences between 3-axle and 2-axle fence semi-trailers? How to choose?
  The 3-axle model features higher load-bearing capacity, more balanced load distribution and better driving stability, suitable for heavy cargo, long-distance transportation and complex rough road conditions. The 2-axle model is lightweight with lower operating costs, more applicable for light and medium bulk cargo. You can select the model according to your daily cargo weight and transport mileage.
• Can I freely raise the fence height of the 3-axle semi-trailer?
  No arbitrary modification is allowed. The fence height and overall dimensions must be manufactured in accordance with official certification parameters for legal registration. Unauthorized height change belongs to illegal refitting, which will cause traffic penalties and failed annual inspection. All customized sizes are strictly within the certified standard range.
• Can the suspension system be upgraded? What options are available?
  Suspension upgrade is supported. The standard configuration is export-grade leaf spring suspension for conventional heavy cargo transport. Air suspension is an optional upgrade with superior shock absorption performance, which is more suitable for transporting livestock, fragile goods and precision equipment.
• What key points should be noted for ordering and registration?
  The overall vehicle dimensions, fence structure and tare weight must be consistent with official certified parameters; 2. The specifications of axles, tires and suspension cannot be altered without official approval; 3. External widened structures are forbidden on side fences to ensure compliance with road and registration regulations.
