Extendable Lowbed Semi Trailer – Long & Oversized Cargo Transport

Extendable Lowbed Trailer for Long & Oversized Cargo Transport

Alura Trailer manufactures Extendable Lowbed Semi Trailers engineered for the safe, stable and regulation-compliant transportation of long, oversized and abnormal cargo such as wind turbine blades, steel structures, bridge components, pipes, beams and industrial modules that exceed standard trailer length limits.

Constructed using ST-52 and Strenx 700MC high-strength structural steel, these extendable lowbed trailers deliver excellent torsional rigidity, controlled deflection and long service life, even under extended deck lengths and demanding road conditions.

Featuring a hydraulic telescopic extension system, low deck height, reinforced gooseneck structure and flexible axle configurations, this trailer is ideally suited for heavy haulage specialists, wind energy logistics, infrastructure projects and international abnormal load transport where adaptability and length flexibility are essential.
