Spring and Walking Beam Suspension
Spring and Walking Beam Suspension is a severe-duty choice for many 3 and 4-axle trailers. The combination of two rubber-bushed walking beams connected by a heavy spring has a "walking" action with increased load stability and positive axle alignment. Spring and Walking Beam Suspension is available in 75,000 lb. and 90,000 lb. capacities for 3-axle trailers; 100,000 lb. and 120,000 lb. capacities for 4-axle trailers. The axle spacing is set at 50".
