Product Detail

Drop deck semi trailer is a specialized version of our standard flatbed, engineered with a lower deck height to accommodate over-height cargo that would exceed legal transport limits on conventional trailers. It is the preferred solution for transporting excavators, drilling rigs, transformers, and large-scale industrial machinery.

Key Technical Advantages

Superior Material and Toughness

Constructed from high-strength, full-thickness steel with a titanium content of 0.98‰, the trailer delivers exceptional toughness and structural integrity under heavy dynamic loads. This precise metallurgical balance reinforces the main beam and frame, making it ideal for demanding mining and construction applications.

Heavy-Duty Loading Capacity

Designed for versatility, our flatbed semi trailer range offers loading capacities from 30 to 100 tons, meeting the transport requirements of oversized machinery and heavy equipment.

Advanced Manufacturing Craftsmanship

Main Beam: Automatic submerged arc welding ensures deep penetration and flawless weld joints for superior strength.
Surface Treatment: Professional shot blasting removes rust and welding residues for improved coating adhesion.
Durability: Electrophoretic coating combined with premium baking paint creates a corrosion-resistant surface with protective performance lasting over 10 years.

Premium Components and Safety

We integrate globally recognized components, including FUWA/BPW axles, JOST landing gear and kingpins, and WABCO braking valves. The emergency brake system features widened brake pads and double air chambers for enhanced stopping power under heavy loads.
