II. Product Details
1. Frame Transport Semi-trailer: Axle Configurations for Targeted Load Requirements
The Frame Transport Semi-trailer offers three axle configurations to match diverse cargo weights and regional road regulations, ensuring optimal efficiency. The 3-axle model (20–30 tons payload) features a 12–17 meter frame platform and 2.5–3.0 meter standard width, ideal for medium-heavy cargo like small excavators (15–20 tons), 12-meter steel profiles, and light prefabricated components-suited for short-to-medium-haul transport in urban construction zones (e.g., China's Yangtze River Delta, India's Delhi-NCR). The 4-axle model (30–45 tons payload) extends the platform to 14–21 meters and supports 2.5–3.5 meter width, designed for heavy cargo such as medium excavators (25–35 tons), 18-meter steel box girders, and industrial boilers-common in cross-provincial infrastructure projects (e.g., EU's highway expansion, US intermodal transport). The 5-axle model (40–60 tons payload) boasts an 17–24 meter ultra-long platform and 2.8–4.0 meter oversized width (requiring special permits), tailored for ultra-heavy cargo like large cranes (50–60 tons), 25-meter prefabricated piers, and heavy-duty generators-critical for energy projects (e.g., Middle Eastern solar farms, African hydropower plants).
2. Frame Transport Semi-trailer: High-Strength Structure for Ultra-Heavy Loads
The Frame Transport Semi-trailer's rigid frame structure is engineered for maximum load-bearing capacity and durability, addressing the core concern of heavy-cargo safety. Its main frame uses Q690/Q960 ultra-high-strength steel (tensile strength ≥690 MPa for Q690, ≥960 MPa for Q960), with main beam thickness of 16–35 mm and crossbeam thickness of 10–20 mm-enabling it to withstand short-term 10% overload (e.g., 49.5 tons for a 45-ton rated model) without deformation. Crossbeam spacing is customizable (300–600 mm): narrower spacing (300–400 mm) suits concentrated loads (e.g., industrial boilers with small contact areas), while wider spacing (500–600 mm) optimizes weight distribution for long cargo (e.g., steel beams). The frame undergoes shot blasting (rust removal grade Sa2.5) + epoxy primer + topcoat treatment, achieving salt spray resistance ≥1,000 hours-ideal for coastal projects (e.g., Southeast Asian port expansions, US Gulf Coast refineries). Additionally, 8–20 sets of bolt holes (Φ20–Φ30 mm) and 4–10 hook rings are pre-installed for securing cargo with steel cables or chains, eliminating the need for on-site modification.
3. Frame Transport Semi-trailer: Cargo-Specific Customization for Versatility
The Frame Transport Semi-trailer offers extensive customizations to adapt to unique cargo characteristics, enhancing its applicability across industries. For construction machinery transport (excavators, loaders), it adds tire 限位槽 (tire slots, 200–300 mm wide) to prevent equipment sliding during turns and hydraulic ramps (load capacity ≥10 tons) for easy loading of low-ground-clearance machinery. For long/overwidth cargo (steel box girders, prefabricated piers), a gooseneck-type frame is available-lowering the front platform height by 150–200 mm to improve driving stability and comply with height limits (≤4.5 meters in most regions). For precision equipment transport (laser cutters, medical imaging machines), heavy-duty air suspension (max load ≥15 tons/axle) replaces standard mechanical suspension, reducing vibration by 30% to protect sensitive components. Regional adaptations include: cold regions (axle heating systems for -30°C startup), high-altitude areas (enhanced air filters for low-oxygen environments), and coastal zones (stainless steel hooks/bolts to resist saltwater corrosion)-ensuring performance in diverse climates.
4. Frame Transport Semi-trailer: Global Safety & Compliance for Market Access
The Frame Transport Semi-trailer integrates robust safety features and multi-region certifications to ensure legal operation and cargo security. Its braking system meets global standards: all models include air brakes + ABS (Anti-lock Braking System) as standard, while 4/5-axle models add EBS (Electronic Braking System) (mandatory in the EU) and ASR (Anti-slip Regulation) to shorten stopping distances by 20% on wet roads and prevent tire slip during heavy-load acceleration. Visibility enhancements include full-body ECE R67-compliant reflective strips (visible at 200+ meters at night) and LED warning lights (for oversized cargo, required in the EU/US)-critical for cross-border transport (e.g., China-Mongolia, EU-US routes). Compliance-wise, it holds certifications such as China's CCC, EU's CE (ECE R10/R74), and US DOT approval-eligible for heavy-transport subsidies in regions like China's "Infrastructure Logistics Support Program" and the EU's "Green Cargo Initiative." For oversized/ultra-heavy cargo, the product also includes documentation support for special transport permits (e.g., China's "Oversized Cargo Transport License," EU's "Special Convoy Authorization").
5. Frame Transport Semi-trailer: Tractor Compatibility & Stability Optimization
The Frame Transport Semi-trailer is designed for seamless compatibility with mainstream heavy tractors and enhanced stability during heavy-load transit. It uses a 90 mm standard kingpin (JOST/BPW brand) compatible with tractors from major manufacturers (Volvo, Sinotruk, Freightliner) with 300–500 HP engines-ensuring sufficient power for uphill climbs (15°+ grades) common in mountainous regions (e.g., the Alps, China's Sichuan Basin). Tire specifications are tailored to axle load: 3-axle models use 11.00R22.5 radial tires (load index ≥148), while 4/5-axle models upgrade to 12.00R22.5 tires (load index ≥152)-all with wear resistance ≥120,000 km for long-haul reliability. Stability features include front/rear anti-roll bars (reducing tipping risk by 40% during turns) and a Tire Pressure Monitoring System (TPMS) (mandatory on 5-axle models) that alerts for underinflation-preventing tire blowouts caused by heavy loads. For empty return trips, 4/5-axle models offer 1–2 liftable axles, reducing tire contact with the road by 20–30% to lower wear and fuel consumption.
6. Frame Transport Semi-trailer: Durability & After-Sales Support for Long-Term Value
The Frame Transport Semi-trailer prioritizes long-term durability and accessible after-sales service to lower clients' total cost of ownership (TCO). Key components use industry-leading brands: BPW/Fuwa axles (service life ≥800,000 km), Continental radial tires (resisting punctures in rough terrain), and WABCO braking systems (reducing maintenance frequency by 30%). The frame's modular design simplifies repairs-damaged crossbeams can be replaced individually without full frame replacement, cutting repair costs by 50%. After-sales support includes a 2-year warranty on core components (frame, axles, braking system) and optional 5-year extended warranties, plus a global service network with 30+ centers (Germany, China, Brazil, South Africa) for on-site maintenance. For trade clients, we also provide spare parts kits (common wear items like brake pads, tires) and technical training for local operators-ensuring minimal downtime even in remote regions (e.g., African mining sites, Southeast Asian rural infrastructure projects).
