Van Box Semi Trailer - 4 Axles - 50 Tons
The 4-Axle 50-Ton Van Box Semi-Trailer (also known as a Quad-Axle Heavy-Duty Dry Freight Van, Extra-Heavy Payload Enclosed Cargo Trailer, or Severe-Service Volumetric Box Semi-Trailer) is a high-capacity, heavy-payload enclosed transport trailer specifically engineered for demanding long-haul regional logistics, mining support supply chains, high-density bulk packaged goods, cement bags, heavy paper rolls, beverages, and sensitive high-value industrial freight. Designed to support a massive 50-ton payload capacity while complying with strict multi-axle highway weight distribution regulations, it features a quadri-axle running gear setup (with optional 1st axle air lift functionality for empty return efficiency). Built on an ultra-reinforced Q345B/Q550/T700 structural steel chassis welded via automated submerged-arc processes, it incorporates a weather-sealed corrugated steel or flat composite enclosure paired with a 4mm or 5mm heavy-duty anti-skid checkered steel floor deck. Outfitted with 4 commercial heavy-duty axles (13T/16T FUWA or BPW), heavy-duty multi-leaf mechanical or air ride suspension, dual rear doors with heavy container-style locking hardware, and a dual-line pneumatic air braking system with WABCO ABS, this 4-axle 50-ton van trailer delivers maximum structural endurance, supreme security, low ton-kilometer operating costs, and long-term fleet return on investment. Fully certified under ISO9001, CCC, CE, and SGS standards

Key Structural & Performance Features
1. Quad-Axle High-Payload Infrastructure
- 50-Ton Certified Load Rating: Featuring four commercial heavy-duty 13T/16T axles (FUWA or BPW), this trailer efficiently distributes up to 50 tons of concentrated payload, complying with regional road-weight limitations and minimizing pavement stress.
- Optional 1st Axle Pneumatic Air Lift: Configurable with an automated air-lift lead axle that raises when traveling empty or lightly loaded, substantially reducing tire scrub, fuel consumption, and toll fees.
- Severe-Duty Mechanical Multi-Leaf Suspension: Equipped with 10-leaf or 12-leaf heavy-duty steel spring packs (up to 16mm leaf thickness) paired with heavy equalizer rockers to maintain dynamic stability across unpaved and rutted highway routes.
2. Reinforced Chassis & Heavy Decking Architecture
- Submerged-Arc Welded Main Chassis: Manufactured using ultra-high-tensile Q345B/Q550/T700 steel via automated submerged-arc welding. Thickened upper and lower flange plates (up to 20mm) deliver exceptional torsional stiffness and eliminate chassis sagging under heavy point loads.
- 4mm/5mm Anti-Skid Steel Floor: Upgraded checkered steel deck plate withstands dynamic forklift wheel loads, heavy pallet drop impacts, and abrasive industrial goods without dishing or permanent deformation.
- Hermetically Sealed High-Security Box: Heavy-gauge corrugated steel or smooth composite body panels with EPDM weather seals isolate freight from dust, rain, and solar exposure, while container-style locking bars protect cargo against theft.
3. State-of-the-Art Braking & Operational Safety
- WABCO Air Braking with ABS: Dual-line pneumatic compressed air braking system equipped with WABCO ABS delivers prompt braking actuation, shortened stopping distances, and complete wheel-lock protection across all 4 axle positions.
- Heavy-Duty Perimeter Securing System: Internal side walls feature recessed heavy-duty steel E-track rails and floor-mounted lashing rings to secure heavy cargo straps, shoring bars, and load dividers.
- Comprehensive LED Lighting Package: Full high-visibility 24V LED lighting system ensures complete road safety during night operations and long-distance intercity transit.
Commercial & Logistics Terms
- Shipping & Delivery: Transported via Ro-Ro vessel, Bulk Cargo vessel, or flat-rack / SKD packaging to optimize international shipping costs.
- Warranty Coverage: 3-Year structural guarantee on the main chassis frame; 1-Year warranty covering axles, landing gear, door locking hardware, and braking components.
- Payment Terms: 30% T/T deposit, 70% balance paid prior to dispatch; irrevocable L/C at sight accepted.
