Products Advantages
Ultra-Low Cargo Platform
The height of the cargo platform is typically between 0.8 and 1.2 meters - 30% to 50% lower than standard trailers. This low deck design simplifies loading and unloading of heavy equipment, while also lowering the center of gravity for improved driving stability and reduced rollover risk.
Modularized Structure
The gooseneck towing section is separated from the cargo deck. On certain models, the platform can be hydraulically lifted or extended in width - for example, from 3 meters up to 4.5 meters - allowing the trailer to adapt to various cargo sizes and shapes with greater flexibility.
Multi-Axle High Load Capacity
Most configurations feature 3 to 8 axle lines, with each axle supporting between 12 and 25 tons. Total load capacity can reach 100 to 200 tons depending on the configuration. This makes the trailer ideal for ultra-heavy industrial cargo such as transformers, wind turbine components, and large mining equipment.

Real Experience with Oversized Cargo
We don't just read blueprints - we understand what it takes to move extra-heavy and extra-wide loads. Our team has supplied trailers for wind turbine blades, power transformers, and large reactors. We know the real challenges on the road, not just the theoretical limits.
We sincerely welcome friends from all over the world to visit our company for win-win cooperation.
