Description
Overview
This heavy-duty lifting and unlifting type semi trailer air suspension is engineered for high-capacity, smooth and efficient vehicle performance. It connects the trailer frame to the axle system, distributes loads evenly, and effectively reduces road vibration. Especially designed for the American market, it improves ride quality and load handling for various trailer types such as flatbeds, tankers, lowbeds, and skeletal trailers.
Compared with traditional leaf spring suspensions, this air suspension system provides lower weight, better shock absorption, and improved fuel efficiency. By adjusting the air volume in the shock absorber, it can control ride height and stiffness, ensuring greater driving stability and cargo protection under variable road conditions.
Application
Our semi trailer air suspensions are widely used in:
- Flatbed, lowbed, van, tanker, and dump trailers
- Car carriers and agricultural transporters
- Full trailers and special-purpose vehicles
