❓ Frequently Asked Questions
What types of mechanical suspension systems do you offer?
We offer a wide range of types including Germany type, American type, York casting type, European type (with parabolic leaf springs), South Africa type, and light-duty versions.
How many axles can be configured in your suspension systems?
Our systems are highly flexible and are available in 1-axle, 2-axle, 3-axle, and 4-axle configurations, as well as single-point suspension systems.
What certifications do your mechanical suspensions have?
Our products have passed the international quality control standard authentications for ISO9001 and ISO/TS16949.
How does the design improve tire service life?
The torque arm angle is scientifically adjusted to reduce the sliding distance between tires and the ground. Coupled with urethane rubber bushings, this minimizes friction and ensures even tire wear.
What materials are used for the spring hangers?
The hangers are manufactured from high-tensile low alloy steel plates that are pressed and welded into a structure that is both stronger and lighter than traditional designs.
Is customized suspension design available?
Yes, we provide customized semi-trailer suspension solutions to meet specific load capacities and technical requirements for different global markets.
