Precast Concrete Beam Lowbed Trailer
The Precast Concrete Beam Lowbed Trailer is a heavy-duty, reinforced lowbed semi-trailer engineered specifically for hauling precast concrete T-beams, box girders, I-beams, bridge segments, and heavy precast building panels. 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. Featuring an extended low deck height (700–1,100 mm) equipped with concentrated load support crossmembers, bolster turntables, and heavy-duty tie-down anchor points, it ensures even weight distribution across axles, prevents structural sagging under extreme concrete mass, and guarantees road bridge height compliance during bridge and infrastructure construction logistics. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Ultra-Reinforced Frame Engineered for Dense Concrete Loads
- High-Tensile Steel Structure: Constructed with Q345B, Q550, Q700, or T700 steel to handle massive point loads and severe bending forces from heavy concrete bridge beams and girders.
- Automated SAW Welding: Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees maximum structural endurance against dynamic load stress 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 crossmembers.
- Anti-Skid Checkered Platform: 4 mm, 5 mm, or 6 mm checkered steel floor reinforced with dense I-beam crossmembers to withstand extreme point pressure from support blocks.
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 rough construction terrain.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent).
3. Concrete Beam Securing & Logistics Accessories
- Bolster Mounts & Turntables: Equipped with adjustable support bolsters or steering turntables to accommodate long bridge beams and negotiate tight road curves.
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for flexible crane loading and weight distribution.
- Width Extension: Outriggers/side brackets extend platform width by 250–300 mm per side to fit wide precast concrete slabs and box girders.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, D-ring anchor points, and ratchet binders to lock rigid concrete beams 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).
