Products Advantages
Precision Steel Cutting
Raw materials are purchased exclusively from famous steel mills. These materials are then processed with a plasma underwater cutting machine, which follows the production drawings to achieve precise dimensions. Main beam and frame built to endure extreme stress without deformation
Low Deck Height
The low deck design positions cargo closer to the road, significantly lowering the center of gravity. This improves stability during cornering and highway travel, reduces rollover risk, and helps tall loads like excavators and crane parts stay within legal height limits under bridges and tunnels. For transport companies, this means fewer route restrictions and reduced need for special permits.
Customizable Configuration
We offer extensive customization to match your specific hauling needs. Choose from trusted axle brands such as FUWA, BPW, or SAF. Select mechanical spring suspension for rugged durability or air suspension for a smoother ride. Tire sizes and landing gear options like JOST are also flexible. This ensures every trailer is a tailored solution built for your routes and loads.
OEM Service Available
If you have your own designs or unique requirements, we provide full OEM manufacturing. Supply your production drawings or technical specifications, and we will build trailers exactly to your documents. This is ideal for maintaining fleet consistency or implementing custom features. Our team follows your drawings precisely, with engineering support available if minor adjustments are needed.
Wide Industry Application
This trailer serves multiple sectors effectively. In construction, it moves excavators, bulldozers, and loaders. For mining, it hauls drilling rigs and crushers over rough terrain. The energy sector uses it for wind turbine parts, transformers, and generators. General heavy logistics companies also rely on it for industrial machinery and oversized cargo, benefiting from the low deck, high capacity, and customization options.
