Durable, Safe, and Compliant Lifting Solutions
Our premium chain slings are engineered for reliability, safety, and optimal performance in demanding industrial environments. Manufactured in compliance with EN 818-4 and EN 818 standards, these slings are rigorously tested to ensure they meet the highest European safety and quality requirements. Available in Grade 8 (Red), Grade 10 (Aquablue), and Grade 12 (Oceanblue), each grade offers distinct strength characteristics tailored to your lifting needs.

Key Features

  • Grade-Specific Strength:

    • Grade 8 (Red): Ideal for general-purpose lifting with a robust working load limit (WLL) suited for medium-duty applications.

    • Grade 10 (Aquablue): Enhanced strength for heavy-duty lifting, offering higher WLLs for challenging industrial tasks.

    • Grade 12 (Oceanblue): Superior performance for extreme loads, designed for the most demanding environments with the highest WLL in its class.

  • Color-Coded for Safety: Easily identify chain grades at a glance with vibrant, durable color markings (Red, Aquablue, Oceanblue).

  • EN 818-4 / EN 818 Compliance: Guaranteed adherence to European safety standards, including a 4:1 design factor for enhanced safety margins.

  • Versatile Configurations: Available in single-leg, double-leg, or multi-leg designs to accommodate diverse lifting angles and load distributions.

  • Corrosion-Resistant: Heat-treated and surface-finished to resist wear, abrasion, and harsh environmental conditions.

Working Load Limits (WLL)

WLLs vary based on chain diameter, grade, and lifting configuration (e.g., vertical, choker, or basket hitch). All values are calculated in strict accordance with EN 818-4 guidelines.

  • Critical Factors:

    • Lifting Angle: Reduced angles increase stress on slings—always consult WLL charts for angle-specific limits.

    • Chain Diameter: Larger diameters support higher WLLs.

    • Safety Factor: EN 818-4 mandates a minimum 4:1 safety ratio, ensuring slings exceed rated capacities.

      Why Choose Our Chain Slings?

      • Unmatched Safety: Built to exceed EN standards with rigorous quality control.

      • Longevity: Precision manufacturing ensures extended service life, even under frequent use.

      • Global Compliance: Suitable for use in EU markets and beyond.

How do you calculate sling load factor?
Sling Angles and Loads
Take the total load weight and divide it by the number of legs supporting the load to get the total minimum load on a sling leg. Determine the load factor by consulting the sling angle factor chart below. Multiply the load factor times the minimum load on a sling leg.

What is the working load limit factor?
Working Load Limit (WLL) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield. The WLL is calculated by dividing the breaking load limit (BLL) by a safety factor (SF).

How do you calculate working load limit?
The WLL is calculated by dividing the breaking strength by the safety factor. For example, if the breaking strength is 10,000 pounds and the safety factor is 5:1, then the WLL is 2,000 pounds
