Side Wall Semi Trailer - 3 Axles - 40 Tons - 600mm Side Wall
The 3-Axle 40-Ton Side Wall Semi-Trailer with 600mm Side Walls is a highly versatile, medium-to-long haul cargo transport trailer engineered specifically for general freight, palletized goods, low-profile bulk commodities, agricultural products, and bagged material. Featuring a 600mm low-profile side wall design, it provides optimum balance between lateral cargo containment and low tare weight, making manual over-the-side loading and forklift operations fast and effortless. Constructed with a high-tensile Q345B/Q550 structural steel main beam welded via automated submerged-arc processes, it incorporates a 3mm or 4mm anti-skid checkered steel floor deck. Equipped with 3 commercial heavy-duty 13T/16T axles (FUWA or BPW), a 10-leaf mechanical spring suspension, and a dual-line pneumatic air braking system with WABCO ABS, this trailer delivers exceptional payload stability, long service life, and reduced fuel consumption across diverse highway and regional transport routes. Fully certified under ISO9001, CCC, CE, and SGS standards.

Key Structural & Performance Features
1. Optimized 600mm Low-Profile Side Wall Architecture
- Low Tare Weight & Easy Access: The 600mm side wall height significantly reduces dead weight while providing safe lateral retention for low-density bulk, crates, and palletized commodities. The low height allows operators to comfortably handle or inspect cargo over the sides.
- Hinged & Detachable Panels: Features corrugated steel panels attached with quick-release hinge pins and heavy-duty corner pillars, allowing individual side sections to drop down or be fully detached for dual-side forklift access.
- Quick Conversion to Flatbed: Removing side panels quickly converts the unit into a flatbed trailer suitable for containerized, long, or oversized structural cargo.
2. High-Tensile Reinforced Frame & Deck
- Submerged-Arc Welded Main Beam: Fabricated using Q345B/Q550 high-tensile steel with an automated submerged-arc welding process. The I-beam geometry delivers excellent resistance to chassis sagging and dynamic flexing under full 40-ton loads.
- Anti-Skid Checkered Floor Plate: Equipped with a 3mm or 4mm thick steel checkered floor deck to prevent cargo movement during transit and withstand high point loads during forklift loading.
- Multi-Point Cargo Securing: Integrated perimeter channel beams equipped with heavy-duty rope hooks, tensioners, and lashing rings ensure straps and tarpaulins stay tightly anchored.
3. Reliable 3-Axle Running Gear & Brake System
- Balanced Tri-Axle Distribution: Features three 13T or 16T capacity heavy-duty commercial axles (FUWA/BPW) to ensure full highway compliance and balanced axle load distribution.
- WABCO Pneumatic ABS Braking: Dual-line air braking system paired with WABCO ABS delivers rapid brake response, short stopping distances, and anti-skid protection on wet or uneven road surfaces.
- Heavy Multi-Leaf Suspension: Standard 10-leaf mechanical spring suspension system dampens severe road impacts, protecting both cargo and frame integrity.
Commercial & Logistics Terms
- Shipping & Delivery: Shipped via Ro-Ro vessel, Bulk Cargo vessel, or 40ft High Cube (40HQ) containers (utilizing bolt-connected split-frame options) to optimize ocean freight costs.
- 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.
