1. Material & Core Specifications
Made of professional high-elastic alloy spring steel strengthened by heat treatment; standard size: 90mm single leaf width, 10 laminated leaves per set, 13mm thick main leaf, 60KG net weight per piece. Gradient leaf thickness design distributes stress evenly, no permanent deformation under long-term heavy load, excellent anti-shock and anti-break performance.
2. Anti-Corrosion & Manufacturing Craft
High-temperature electrostatic plastic spraying for strong paint adhesion, resistant to rain, mud and saline-alkali harsh conditions to delay steel corrosion long-term. Every steel leaf goes through precise rolling, straightening and stress relief treatment for lasting stable elasticity, longer service life than thin low-grade leaf springs.
3. Structural & Assembly Design
10-layer combined structure fixed by 2 steel clamps and center positioning bolt to avoid leaf dislocation during transport and driving. Integrated bent hanger eye on one end for accurate connection with trailer suspension bracket. Clear "Left / Right" marking on surface for easy installation identification to prevent reverse assembly.
4. Core Functions
As the core load-bearing component of trailer suspension, it bears vehicle and cargo weight; buffers road vibration to reduce wear of tires, axles and frame; restrains high-speed rollover and lowers risk of cargo damage, suitable for long-distance trunk logistics and construction heavy transport.
5. Quality & Matching Advantages
Manufactured by Shandong Taiyue with independent inspection certificate, all units pass pressure & fatigue test before delivery. Standard dimension allows direct replacement without modification. Matched perfectly with 13T 1840mm American trailer axle for one-stop trailer suspension matching. Sold in left-right pair for convenient maintenance replacement.
6. Application
Widely compatible with 13-ton flatbed semi-trailers, fence trailers, container skeleton trailers and dump freight trailers; universal replacement part for long-distance logistics, engineering heavy transport and export trailer refitting.
