Heavy Steel Structure Transport Lowbed Trailer
The Heavy Steel Structure Transport Lowbed Trailer is an extra-heavy-duty lowbed semi-trailer engineered specifically for moving oversized steel trusses, heavy H-beams, bridge steel girders, prefabricated building frames, and industrial structural steel assemblies. Built with a load capacity ranging from 30 to 150+ tons, it is constructed using Q345B/Q550/Q700/T700 high-tensile steel and automated submerged-arc welding. Its extended low deck height (700–1,100 mm) paired with high-density crossmembers, stake pockets, multi-point lashing rings, and side outriggers provides exceptional resistance against frame torsion, ensures optimal weight distribution, and strictly respects highway overhead bridge height clearances during heavy construction logistics. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Ultra-Reinforced Frame Built for Extreme Torsion & Point Loads
- High-Tensile Steel Construction: Fabricated with Q345B, Q550, Q700, or T700 steel plates, engineered to resist bending moments and severe point loads from long, heavy steel trusses and girders.
- Automated SAW Welding: Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees maximum structural endurance against dynamic load shock and chassis torsion.
- Heavy Main Beam Profile: Main beam height options of 450 mm, 500 mm, or 520 mm with extra-thick top and bottom flange plates and high-density I-beam crossmembers.
- Anti-Skid Checkered Platform: 4 mm, 5 mm, or 6 mm checkered steel floor reinforced to withstand extreme concentrated pressure from steel beam contact points.
2. Axle, Suspension & Braking Systems
- Axle Configurations: 2 to 6 axles (Supports FUWA, BPW, Huajin, or equivalent premium brands; 13T / 16T / 20T / 25T capacity per axle).
- Tire & Rim Setup: 8 to 24 heavy-duty tires paired with 6.75-17.5 or 9.00-22.5 high-load steel rims.
- Suspension Options: Multi-leaf heavy-duty spring suspension (10/12 leaves) or shock-absorbing air suspension system for smooth transport over job site terrain.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent).
3. Steel Structure Securing & Cargo Accessories
- Stake Pockets & Removable Pillars: Equipped with heavy-duty stake pockets along the deck sides and removable steel pillars to prevent tall steel trusses and stacked beams from shifting laterally.
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for flexible crane and forklift loading scenarios.
- Width Extension: Outriggers/side brackets extend platform width by 250–300 mm per side to fit wide steel frame modules.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, D-ring tie-down anchor points, and ratchet binders to lock rigid steel structures firmly in place.
- Standard Accessories: 28-Ton two-speed landing gear (JOST / FUWA), 50# (2") or 90# (3.5") interchangeable kingpins, 24V 7-pin LED lighting system, 1–2 spare tire carriers, and a waterproof tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam; 1-Year warranty for axles.
- Delivery Lead Time: 25 – 35 working days upon order confirmation.
- Packaging & Shipping: Nude packing; shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
