Product Features & Applications

This trailer leaf spring assembly adopts mainstream size 75×13 with 9-leaf stacked structure, made of high-toughness alloy spring steel with full quenching and tempering heat treatment, wear and fatigue resistant, no crack under long-term heavy load. Multi-layer design balances load capacity and shock absorption, compatible with 13t and 16t standard trailer axles, fits tipper, flatbed, container and curtain side semi-trailers. Size, leaf quantity and thickness can be customized. Complete with clamps and positioning bolts for easy installation, meets export inspection standards, available for single set retail and bulk matching for trailer factories.

  • Semi-trailer leaf spring is the core load-bearing and shock-absorbing component of trailer suspension, widely matched with freight and mine engineering semi-trailers. Mature leaf spring structure adapts to global long-distance heavy transport.
  • Material & Process: Made of special high-elastic alloy spring steel, integrally stamped, with high-temperature quenching and low-temperature tempering heat treatment to eliminate internal stress, improve toughness, superior anti-fatigue and anti-crack performance than ordinary steel, durable on rough mine roads and continuous heavy load.
  • Structural Design: Multi-layer stacked steel plate (75×13, 9 leaves as shown), uniform thickness and dispersed force, greatly reduce impact on axles and frames, lower cargo bump loss. Equipped with special fixing clamps and high-strength positioning bolts for stable assembly without dislocation.
  • Application Range: Standard version matches 13t and 16t American-style trailer axles, universal for tipper, low-bed, container and curtain side trailers. Leaf quantity, steel width and thickness can be adjusted according to customer load demand, extra thick extra leaves available for heavy mine trailers.
  • Supply Advantage: Mass production by standardized assembly line with unified dimensional precision, strong part interchangeability for easy overseas maintenance. Palletized container shipment available, favorable price for bulk trailer factory purchase, full factory inspection certificates and export documents provided.
