A semi-trailer suspension is a critical component connecting the traveling device to the frame. It transmits all forces between the road and the vehicle, reducing the impact of harsh terrains, providing shock absorption, and significantly improving ride comfort.
These suspensions are widely applied to skeletal trailers, lowbed trailers, flatbed trailers, dump trailers, oil tank trailers, and more. Our range includes German series, American series, bogie suspensions, air suspensions, and rigid suspension series.
