American type mechanical suspension(three-axle)

Model Number:With ten 13*75 steel plate spring

American type three axle mechanical suspension is a heavy-duty trailer suspension system designed to support high load capacity and improve stability through a tridem axle configuration. This system uses leaf springs, equalizers, and hangers to distribute weight evenly across three axles, ensuring reliable performance under demanding transport conditions.
The three axle configuration significantly increases load capacity and enhances driving stability, making it ideal for heavy-duty trailers operating on highways and rough roads. The leaf spring suspension effectively absorbs shocks and reduces vibration, protecting both the trailer structure and transported cargo.
Jiuzhou Machinery provides durable American type three axle mechanical suspension systems with customizable specifications to meet various heavy transport requirements.

Applications:
 • Heavy-duty semi trailers
 • Mining and construction transport
 • Bulk cargo transportation
 • Long-distance logistics

1.Proven Mechanical Leaf Spring System
This suspension utilizes a traditional leaf spring design, offering robust support and shock absorption ideal for heavy-duty trailer applications.
2.High-Quality Steel Springs
Manufactured from premium steel, the springs provide excellent load-bearing capability and resilience against wear and fatigue.
3.Precision Engineering
All components are engineered with tight tolerances to ensure smooth operation, reduced vibration, and extended service life.
4.Wide Compatibility
Designed to fit a broad range of American-style trailer axles and chassis, making installation and maintenance straightforward.
