Product Features & Applications

This multi-leaf leaf spring model TYG1390104-0A is special suspension shock-absorbing part for 13-ton American-style semi-trailers, single unit net weight 60KG, specification: 90mm width, 10 laminated leaves, 13mm thick main leaf, sold as matched left & right set. It is made of high-toughness alloy spring steel via quenching and tempering heat treatment. Multi-layer laminated structure delivers strong load capacity and outstanding cushioning performance. The whole piece adopts black electrostatic plastic spraying for anti-rust & anti-corrosion, anti-fatigue and anti-fracture under heavy load. Pre-assembled with 2 fixing clamps and center bolt, standardized size perfectly matches 13T 1840mm American trailer axle chassis. It effectively buffers road impact, protects frame, axle and cargo, and greatly improves driving stability for long-distance freight.

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.
