Key Benefits & Features
High Strength Materials:
All critical components are made from Q345B structural steel and forged steel, ensuring resistance to fatigue, overload, and impact.
Corrosion Protection:
Surface treatments like electrophoretic coating or powder painting protect against rust and extend service life - ideal for coastal, muddy, or humid conditions.
Superior Shock Absorption:
The equalizer beams work in sync with multi-leaf springs to distribute loads and absorb road impacts, reducing wear on your frame and axle.
Universal Compatibility:
Designed to fit 13T, 16T, 20T, and 25T American-style axles with easy installation on a wide range of trailer types.
Low Maintenance & Long Service Life:
Optimized structure and fewer wear-prone joints mean less downtime and higher operational efficiency.
Flexible Applications:
Perfect for flatbed trailers, skeleton/container chassis, dump trailers, logistics trailers, and agricultural transport vehicles.
