Tri-Axle 40ft High-Bed Off-Road Container Trailer
The Tri-Axle 40ft High-Bed Off-Road Container Trailer is an extreme-terrain commercial transport semi-trailer engineered specifically for unpaved roads, mining access routes, oilfield construction sites, and remote cross-country logistics. Built with high-strength Q345B/Q550 structural steel and automated submerged-arc welding, it features an elevated chassis frame with exceptionally high ground clearance, heavy-duty underbody protection, and reinforced cross-members to prevent bottoming out over severe rutted or rocky terrain. Equipped with 12 multi-position twist-locks, 3 heavy-duty 16T off-road axles, large-diameter off-road tires, and heavy-duty mechanical leaf spring suspension, it delivers maximum terrain capability and load stability under challenging off-grid transport conditions. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. High Clearance Frame & Extreme-Terrain Chassis Architecture
- Elevated High-Bed Architecture: Designed with exceptional ground clearance and optimized approach/departure angles to prevent undercarriage hang-ups when traversing steep inclines, deep ruts, and unpaved off-road sites.
- Q345B/Q550 Heavy-Duty Spine: Main longitudinal beams welded using continuous automated Submerged-Arc Welding (SAW) with thickened upper/lower flanges to handle intense dynamic twist and impact loads.
- Reinforced Underbody & Cross-Members: Features closely spaced cross-members and heavy-duty steel skid protection plates to shield air tanks, brake chambers, and wiring harnesses from rocks and debris.
2. Axle, Suspension & Pneumatic Braking Systems
- Heavy Off-Road 16T Axles: 3 heavy-duty 16T axles (FUWA / BPW / HuaJin) with expanded wheel tread and off-road hub assemblies designed specifically for severe gravel, sand, and muddy conditions.
- Severe-Duty Mechanical Suspension: Reinforced multi-leaf spring suspension (up to 12pcs, 100x18mm) with heavy-duty equalizers and torque rods to maintain axle alignment on uneven terrain.
- Protected Pneumatic Braking System: Dual-line air braking system with ABS (WABCO / Kemi / Haldex) equipped with protective steel guards over brake chambers and valves for off-road reliability.
3. Operational Accessories & Logistics Setup
- Off-Road Landing Gear & Kingpin: 28-Ton two-speed heavy-duty landing gear with wide swivel footplates to prevent sinking into soft ground, paired with a reinforced 50#(2") or 90#(3.5") kingpin.
