Engineering & Technical Specifications
Main Beams: Fabricated via automated submerged arc welding (SAW). Flanges and webs utilize quenched and tempered structural steel plates (yield strength >= 460 MPa), delivering high fatigue resistance against cyclic vertical bending moments.
Twist Locks: Four (4) or Twelve (12) ISO-standard cast steel twist locks (Grade 45 steel, drop-forged and heat-treated), rated for 32 metric tons tensile load per lock, featuring secondary safety retention latches.
Axles: Dual or tri-axle configurations. 150x150 square beam axles (Capacity: 2x 13T to 20T per axle, compatible with BPW, FUWA, or JOST specifications), fitted with non-asbestos heavy-duty brake linings (420 x 180 mm).
Suspension System: Heavy-duty mechanical multi-leaf spring suspension (90mm width, 10-leaf packs) or slosh-resistant trailing arm air suspension integrated with height control leveling valves.
Kingpin: 2-inch or 3.5-inch interchangeable bolted kingpin (JOST brand), forged from 40Cr alloy steel and induction hardened.
Landing Gear: Two-speed manual landing legs with a static load rating of 80,000 kg and a lifting capacity of 28,000 kg.
Material Selection & Manufacturing Process
Steel Traceability:
Raw structural plates sourced directly from primary mills, accompanied by mill test certificates (MTC) verifying chemical composition and mechanical properties for every production batch.
Surface Preparation:
Assembled chassis frames undergo abrasive blast cleaning to ISO 8501-1 Sa 2.5 standard to remove mill scale, oxides, and surface contaminants prior to coating.
Corrosion Protection System:
Primer: Dual-component zinc-rich epoxy primer (dry film thickness >= 75 um).
Topcoat: Polyurethane high-gloss finish coat (dry film thickness >= 50 um), salt-spray tested for a minimum of 1,000 hours without blistering or adhesion loss.
Weld Integrity: 100% visual inspection on all structural welds. Critical stress-bearing junctions on the gooseneck and suspension brackets undergo ultrasonic testing (UT) or magnetic particle inspection (MPI) per AWS D1.1 standards.
Quality Control & Compliance Standards
Proof Load Testing: Every manufacturing lot undergoes static load testing at 1.25x rated payload capacity on a structural testing rig to verify permanent deflection margins.
Braking System: Equipped with WABCO or Haldex ABS braking systems (2S/2M configuration), compliant with UN ECE R13 or FMVSS 121 regulations, paired with Type 30/30 spring brake chambers.
Electrical Architecture: 24-volt, 7-pin ISO wiring harness housed in flame-retardant PVC corrugated tubing; sealed LED lighting arrays compliant with DOT (FMVSS 108) or ECE standards.
Certifications: ISO 9001:2015 manufacturing quality management system compliance, with World Manufacturer Identifier (WMI) assigned for official 17-digit VIN decoding.
Application Suitability
Port Drayage: Short-to-medium haul movement of maritime containers from terminal crane aprons to near-dock rail transfer yards.
Intermodal Rail Yards: Engineered with precise dimensional tolerances to accept standard container bottom corner castings without binding during automated crane handling.
Heavy Freight Corridors: Optimized tare weights allow fleet operators to maximize cargo payloads within legal gross vehicle weight rating (GVWR) limits.
FAQ
Q: Can the gooseneck height and kingpin location be customized for regional tractor compatibility?
A: Yes. Standard gooseneck drops range from 120mm to 200mm, and kingpin settings can be configured (e.g., 500mm to 900mm from the rear face of the front bolster) to align with specific 4x2 or 6x4 tractor turning clearance and weight distribution requirements.
Q: What is the standard production lead time for a fleet order of 20 chassis units?
A: Manufacturing requires 35 to 45 business days upon technical drawing approval and receipt of deposit. Ocean transport is typically executed via flat-rack vessels or stacked in sets of 3 to 4 units in breakbulk carriers.
Q: How is frame cracking prevented at the high-stress gooseneck transition zone?
A: We integrate internal reinforcement gussets and full-penetration robotic welds combined with high-yield Q460C steel plates, mitigating abrupt stress concentrations that cause fatigue cracking under heavy eccentric 20ft container loads.
Q: What documentation is supplied for local vehicle registration?
A: Each chassis ships with a complete compliance dossier including the Certificate of Origin, Bill of Lading, Commercial Invoice, steel MTCs, 17-digit WMI VIN plate, and individual axle/brake test reports.
