Extendable Telescopic Flatbed Semi-Trailer

The Extendable Telescopic Flatbed Semi-Trailer is a specialized, adjustable-length commercial transport semi-trailer engineered specifically for over-length, oversized, and long-span cargo logistics such as wind turbine components, steel beams, pipes, and structural elements. Built with high-strength Q345B/Q550 structural steel and automated submerged-arc welding, it features a robust telescopic sliding beam mechanism that allows the deck length to expand and retract seamlessly based on project requirements. Equipped with heavy-duty twist-locks, durable 13T-16T axles, and robust mechanical or air suspension, it delivers flexible, heavy-duty performance across complex long-haul transport routes. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features

1. Telescopic Sliding Mechanism & High-Tensile Spine

  • Heavy-Duty Telescopic Beam Design: Engineered with a robust inner-sleeve sliding box-beam structure driven by multi-stage locking pins, allowing the overall trailer length to extend smoothly from standard dimensions up to 20 meters for oversized freight.
  • Q345B/Q550 High-Strength Spine: Main longitudinal chassis frames fabricated from high-yield steel plates and automated Submerged-Arc Welding (SAW), providing supreme structural stiffness and sag-resistance across extended spans.
  • Reinforced Platform Flooring: Durable 3mm/4mm checkered plate flooring ensuring high surface grip, wear resistance, and long-lasting durability under extreme dynamic loads.

2. Axle, Suspension & Pneumatic Braking Systems

  • Heavy-Duty Commercial Axles: 3 or 4 premium commercial axles (FUWA / BPW / HuaJin brands; 13T/16T capacity per axle) calibrated for high gross vehicle weights and heavy concentrated payloads.
  • Robust Suspension Configuration: Advanced heavy-duty leaf springs (10pcs, 90x13mm / 90x16mm) or air suspension designed to absorb severe road impacts and maintain exceptional stability at extended lengths.
  • Advanced Braking System: Equipped with an ABS Anti-lock Braking System (WABCO / Kemi / Haldex brands) to ensure responsive, safe, and stable stopping performance under full loads.

3. Operational Accessories & Logistics Setup

  • Landing Gear & Kingpin: Heavy-duty 28-Ton two-speed landing gear (JOST / FUWA) combined with interchangeable 50#(2") or 90#(3.5") kingpins for reliable tractor coupling.
  • Electrical & Lighting System: Weatherproof 24V LED lighting system featuring an extended wiring harness, 7-pin socket, and side marker clearance lights required for over-length vehicle compliance.
  • Surface Treatment: Thoroughly prepared via sandblasting followed by one anti-rust primer layer and two coats of high-grade finish paint for long-lasting environmental protection.

Commercial & Logistics Terms

  • Warranty Policy: 3-Year warranty for the main structural chassis frame and telescopic sliding assembly; 1-Year warranty for axles.
  • Delivery Lead Time: 30 – 35 working days upon order confirmation.
  • Packaging & Shipping: Nude packing; shipped via Ro-Ro vessel, Bulk Cargo ship, or specialized flat-rack container.
  • Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
