Oversized Cargo Lowbed Semi-Trailer
The Oversized Cargo Lowbed Semi-Trailer
is an heavy-haul transport semi-trailer custom-engineered for moving
over-dimensional, over-length, over-width, and heavy non-dismountable cargo,
including industrial pressure vessels, wind turbine components, large
transformers, and heavy manufacturing equipment. Featuring a load capacity
ranging from 30 to 150+ tons, it is constructed from Q345B/Q550/Q700/T700
high-tensile steel using automated submerged-arc welding. Its ultra-low
platform design (700–1,100 mm) paired with extendable side brackets, modular
frame options, and heavy-duty ramps lowers the overall cargo height to meet
highway bridge clearances while ensuring maximum lateral stability and safety
during heavy-haul transit. Fully certified under ECE, ISO9001, CCC, CE, DOT,
and SGS standards.

Key Structural & Performance Features
1. Heavy-Duty Frame Built for Over-Dimensional Payloads
- High-Tensile Steel Structure: Fabricated with Q345B, Q550, Q700, or T700 steel to support extreme concentrated point loads from massive industrial machinery and structural steel components.
- Automated SAW Welding: Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees superior frame durability under heavy dynamic loads and torsion.
- Reinforced Main Beams: Main beam height options of 450 mm, 500 mm, or 520 mm with extra-thick top and bottom flange plates.
- Anti-Skid Checkered Platform: 4 mm, 5 mm, or 6 mm checkered steel floor engineered with reinforced crossmembers to handle severe concentrated tire and steel support loads.
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: Heavy-duty multi-leaf spring suspension (10/12 leaves) or shock-absorbing air suspension system.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent).
3. Oversized Loading & Securing Setup
- Extendable Side Outriggers: Outriggers/side brackets extend platform width by 250–300 mm per side to accommodate wide industrial equipment and modules.
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for smooth cargo loading and optimal weight distribution.
- Heavy-Duty Ramps: Mechanical, hydraulic, or spring-assisted ramps with low climb angles for rolling equipment and heavy machinery access.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, D-ring tie-down points, and ratchet tighteners ensure zero-movement transport safety.
- 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 placement.
- 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).
