Big truck suspension systems in our inventory are engineered for heavy loads and diverse terrains. Air suspension systems (common in long-haul) use electronically controlled air bags (28L volume), maintaining ride height within ±15mm under loads up to 40 tons, with variable damping (800–1,200 N·s/m) for smooth operation. Leaf spring suspensions (construction use) feature multi-leaf steel springs (90x12mm) with parabolic profiles, supporting axle loads up to 18 tons, and include friction dampers to reduce vibrations. Hydraulic suspension systems (off-road) offer 300mm vertical travel, nitrogen-charged shocks (12,000N rebound), and self-leveling for uneven terrain. All systems include anti-roll bars (45mm diameter) to reduce lateral sway by 40%.
