Applications
A semi-trailer suspension is an important part connecting the traveling device and the frame of the semi-trailer.
All forces are all transmitted through the suspension system. And the suspension reduces the impact of harsh roads on the vehicle, plays a shock absorption effect, and improves the ride comfort of the vehicle.
Semi-trailer suspensions are widely applied to skeletal trailers, lowbed trailers, flatbed trailers, dump trailers, car transport trailers, oil tank trailers, van trailers, full trailers, wood transport trailers, agricultrucal vehicles, etc. Classification of suspension indlude German series suspensions, American series suspensions, bogie/boogie suspension series, air suspension series, rigid suspension series, YORK suspensions, ROR suspensions, HENRED suspensions, semi-trailer suspensions, trailer suspensions and agricultural series, etc.
