Applications
Semi-trailer suspensions serve as a critical component linking the running gear to the vehicle’s frame, ensuring seamless force transmission across all operational conditions. By mitigating road-induced vibrations and shocks, these systems safeguard cargo integrity, enhance vehicle stability, and optimize driver comfort during long-haul transport.
Their versatility extends across diverse trailer types, including skeletal trailers for containerized freight, lowbed designs for heavy machinery, flatbeds for versatile cargo, dump trailers for bulk materials, car carriers for automotive logistics, tankers for liquid transport, enclosed vans for temperature-sensitive goods, full trailers for combined loads, timber haulers for forestry products, and agricultural trailers for farm equipment.
Suspension systems are further categorized by design and functionality, encompassing German-engineered precision series, American-standard robust models, bogie/tandem axle configurations for weight distribution, air-ride suspensions for smoothness, rigid beam suspensions for durability, specialized YORK/ROR/HENRED variants, and agricultural-focused solutions tailored to rugged terrains and payload demands.
