BLT092 Rigging Hardware
- Working Load Limit 4-31.5t
- Pivot 180 degree
The weld-on load ring is engineered for heavy-duty lifting and anchoring applications, offering a working load limit of 4-31.5t and 180° pivot functionality. Designed for permanent attachment via welding, the lashing load ring creates a stable and secure lifting point ideal for industrial, and oil & gas operations.
Inspection and Standards
- Tested with 1.5x load fatigue cycles (20,000 cycles) and 2.5x rated load tests for exceptional durability
- Inspected using magnetic particle testing to ensure no surface cracks or defects
- Produced in accordance with EN1677-1 standards, with certified test reports available upon request
Applications
- Transportation: Ideal for lifting and transportation of heavy cargo, oversized components and containers, minimizing errors and reducing the risk of collisions or damage.
- Industrial plants: Commonly used for lifting industrial generators, boilers, compressors, and other heavy machinery in factories.
Key Features
- Offers 180° pivot capability for flexibility in lifting and secure load positioning
- Work load limited (WLL) of 4-31.5t ensures compatibility with various heavy-duty applications
- Built with a 4:1 safety factor and subjected to 100% non-destructive testing for reliability
- Forged from high-strength chromium-molybdenum alloy steel, quenched and tempered for enhanced durability
- Coated with epoxy resin electrostatic powder for long-term corrosion resistance, making it suitable for harsh environments

Welding Conditions
- The carbon content of the base material must be below 0.4%.
- If the ambient temperature is below 10°C, preheat the surface before welding.
- Welding should not be performed in open areas or under adverse weather conditions.
Welding Methods
- Ensure the contact surface is clean and free from metal shavings, oil, paint, slag, or other contaminants. Corroded or painted surfaces must be completely cleaned of rust and paint before welding.
- Clean the weld seam before proceeding to the next pass to avoid slag inclusions.
- Once welding starts, do not interrupt the process to prevent component cooling.
- Thoroughly inspect the weld points to ensure there are no cracks, dents, or scratches. If concerns arise, use non-destructive inspection methods, such as magnetic particle or dye penetrant testing.
- For repairs, grind out any defects and repeat the welding process with qualified procedures.
- Avoid rapid cooling of the weld points.
