Products Advantage
Definitive Load-Bearing Capability
It defines the category of extreme hauling. Engineered to legally transport what others cannot, it is the essential solution for moving core machinery in sectors like mining and wind energy.
Self-Sufficient Loading System
The low-profile deck with a liftable front section enables equipment to drive on under its own power. This transforms loading from a crane-dependent operation into a rapid, autonomous process completed in minutes.
Stable Transport Across All Terrains
Precision engineering ensures smooth transit for over-dimensional loads over long distances and variable road conditions, providing a secure "mobile platform" for critical cargo.
Engineered for Structural Longevity
Reinforced at key stress points with high-grade materials, it guarantees structural integrity under repeated heavy loads and harsh conditions, significantly reducing maintenance demands.ments.
A Long-Term Value Asset
High operational uptime and an extended service life translate into measurable economics, delivering the lowest cost per move and optimal lifecycle return on investment.
customer feedback
Long-distance Transportation & Stability
We've been using Liangyu heavy haul trailers for transporting large construction machinery across Central Asia for over 2 years. The low-bed design keeps the center of gravity stable, and even on bumpy rural roads, the cargo hardly shakes. We've completed more than 50 long-haul trips without any rollover risks, which greatly ensures the safety of our high-value equipment. The build quality is solid, and the trailer has shown no signs of wear even after frequent heavy loads. Highly recommended for companies engaged in cross-border heavy cargo transportation.
Customization & After-sales Service
As a mining company in South Africa, we have special requirements for the length and load capacity of heavy haul trailers. Liangyu's team fully communicated with us to understand our needs and provided a customized solution. The trailer fits perfectly with our mining equipment, and the hydraulic lifting ladder makes loading and unloading much more efficient. What impresses us most is their after-sales service-when we encountered a minor issue during use, their local service team responded within 48 hours and solved it professionally. Truly a reliable partner.
Durability & Harsh Environment Adaptability
Our fleet operates in the desert areas of the Middle East, where the environment is harsh with high temperatures and sandstorms. Liangyu heavy haul trailers have exceeded our expectations in durability. The anti-corrosion coating effectively resists sand erosion, and the chassis structure remains stable even after long-term exposure to extreme temperatures. We use them to transport large tanks and power station equipment, and the trailers have maintained excellent performance without frequent maintenance. They are definitely suitable for harsh working conditions.
Cost-effectiveness & Operational Efficiency
Compared with other brands we've used before, Liangyu heavy haul trailers offer outstanding cost-effectiveness. The initial investment is reasonable, and the low maintenance cost saves us a lot of money in the long run. The adjustable body height and length allow us to adapt to different cargo types, reducing the need for multiple trailers. Since switching to Liangyu, our transportation efficiency has increased by 30%, and the loss rate of cargo has dropped significantly. It's a wise choice for improving operational profitability.
