40–100T Load Capacity: Built for wind power, construction, and heavy haul transport.
Strong Welding Integrity: Submerged arc welding ensures durable telescopic joints.
Anti-Corrosion Protection: Shot blasting + electrophoretic coating for 10+ years durability.
Flexible Steering Options: Hydraulic or self-steering axles for better maneuverability.

Product Detail

Extendable Semi Trailer (also known as a Telescopic Trailer) is engineered specifically for the transportation of exceptionally long loads that a standard flatbed cannot handle. With its high-strength telescopic beam, this extending trailer can extend from a standard length to over 147 feet (45 meters), making it the premier choice for wind turbine blades, bridge girders, and long steel structures.

Key Technical Advantages

Heavy-Duty Telescopic Beam: The core chassis features a multi-stage telescopic design, allowing for seamless extension and retraction. The locking system is reinforced to ensure the frame remains rigid and stable even at its maximum length.
High-Tensile Q345B/T700 Steel: To prevent sagging under extreme lengths, we use full-thickness high-tensile steel with a titanium content of 0.98‰, providing superior toughness and a loading capacity of 40 - 100 Tons.
Precision Engineering & Durability:
- Welding: Advanced Submerged Arc Welding ensures the telescopic joints are as strong as a single piece of steel.
- Surface Protection: The entire frame undergoes shot blasting and electrophoretic coating, offering a rust-resistant finish that lasts over 10 years, even in harsh coastal wind farm environments.
Steerable Axle Options: For trailers extending beyond 984" (25m), we offer Self-Steering or Hydraulic Steering Axles to significantly reduce the turning radius and ensure maneuverability on narrow mountain roads.

Industry Applications & Solutions

Wind Power Logistics
Fuyuan solutions are designed for transporting wind turbine blades and tower sections in renewable energy projects. The extendable structure allows flexible adjustment for different blade lengths, while maintaining a low center of gravity for stable long-distance transport. The extendable trailer is widely used in wind farm logistics where safety and adaptability are critical.
Infrastructure & Construction
For large-scale civil engineering projects, Fuyuan equipment supports the transport of bridge girders, pre-cast concrete beams, and oversized steel pipes. The reinforced chassis of the extendable truck trailer ensures strong load-bearing performance and reliable stability even under complex road conditions, making it suitable for demanding construction environments.
Specialized Heavy Hauling
For non-standard and oversized cargo, Fuyuan provides tailored configurations including side outriggers for extra-wide loads and manual or hydraulic steering systems for improved maneuverability on narrow or complex routes. These engineered solutions help operators complete challenging transport tasks with higher efficiency and control.
