Side Wall Semi Trailer - 3 Axles - 50 Tons - 800mm Side Wall
The 3-Axle 50-Ton Side Wall Semi-Trailer with 800mm Side Walls is a heavy-duty, reinforced cargo transport trailer engineered specifically for long-haul logistics, heavy bulk commodities, agricultural products, bagged cement, and industrial freight. Featuring an optimized 800mm side wall height, it delivers enhanced lateral cargo retention while maintaining excellent versatility for dual-side forklift loading and manual side operations. Built with a high-tensile Q345B/Q550 structural steel frame using automated submerged-arc welding, it features a 3mm or 4mm anti-skid checkered steel floor plate. Fitted with three heavy-duty 16T commercial axles (FUWA or BPW), a 10-leaf reinforced mechanical spring suspension, and a dual-line pneumatic braking system with WABCO ABS, this trailer provides exceptional payload stability, severe-duty chassis endurance, and long-term operational durability. Fully certified under ISO9001, CCC, CE, and SGS standards.

Key Structural & Performance Features
1. Heavy-Duty Frame & 800mm Side Wall Design
- Heavy Structural Main Beam: Manufactured with high-tensile Q345B/Q550 steel using automated submerged-arc welding. Thick top and bottom flange plates (up to 16mm–20mm) prevent chassis deflection and sagging under full 50-ton payloads.
- 800mm Reinforced Side Panels: The 800mm side wall height provides superior containment for bulk commodities and stacked crates. Hinged, multi-segment corrugated panels can be dropped down or removed entirely for convenient dual-side loading.
- Anti-Skid Steel Deck: Equipped with a 3mm or 4mm checkered steel floor plate engineered to withstand high point loads from forklifts and machinery tires without deformation.
2. Multi-Point Cargo Retention & Conversion
- Integrated Perimeter Lashing Anchors: Heavy-duty side channel beams fitted with multi-position rope hooks, lashing rings, and winches ensure cargo, tarpaulins, and straps remain secure during transit.
- Fast Flatbed Conversion: Detaching the 800mm side walls and removable corner pillars converts the unit into an open flatbed trailer suitable for containerized or long structural cargo.
- Durable Hinge Latches: Features cast steel hinge sockets and spring-loaded locking pins to maintain panel rigidity and eliminate rattling under heavy vibrations.
3. Severe-Duty 3-Axle Running Gear & Brake Safety
- Heavy-Duty 16T Axle Setup: Three 16-ton capacity commercial axles (FUWA/BPW) paired with 12.00R20 or 12R22.5 heavy-duty radial tires ensure compliant axle weight distribution and high-load endurance.
- WABCO Air Braking with ABS: Dual-line compressed air braking system with WABCO ABS delivers rapid stopping response and anti-skid safety under maximum payload conditions.
- Reinforced Multi-Leaf Suspension: Extra-thick 10-leaf mechanical spring suspension absorbs harsh impacts, balancing vehicle dynamic stability across uneven road surfaces.
Commercial & Logistics Terms
- Shipping & Delivery: Transported via Ro-Ro vessel, Bulk Cargo vessel, or 40ft High Cube (40HQ) container (utilizing bolt-connected split-frame options) for cost-effective ocean freight.
- Warranty Coverage: 3-Year structural guarantee on the main chassis frame; 1-Year warranty covering axles, landing gear, braking valves, and mechanical components.
- Payment Terms: 30% T/T deposit, 70% balance paid prior to dispatch; irrevocable L/C at sight accepted.
