Supplier's note

  1. Three Breakthroughs:

    • Material Strength: High-tensile steel outperforms standard springs by 20% in fatigue resistance.
    • Universal Compatibility: Single design fits all Volvo EC-series models, reducing inventory costs.
    • Extended Warranty: 6-month coverage reflects confidence in durability.

  2. Optimal Version Selection:

    • Base Model: Ideal for routine maintenance in dry environments (e.g., urban construction).
    • Advanced Model: Zinc-plating and enhanced load capacity suit moderate-duty use (e.g., gravel sites).
    • Pro Model: Triple the corrosion resistance of industry standards enables safe operation in saltwater or chemical-exposed areas. With its 2,500-cycle lifespan, it’s unmatched for heavy machinery in mining or offshore projects.

*Note: Comparative values reflect improvements over industry benchmarks (e.g., ISO 1364-1:2017).
