Product Description

Product Description

The A343 Master Link is a high-strength forged or welded alloy steel component designed for critical lifting and rigging applications. Engineered to meet rigorous international standards like EN 1677-4 (superseding DIN 5688-3) , it serves as a versatile connection point for chain slings, wire rope slings, and synthetic slings. Its robust design features a large inner dimension, allowing direct attachment to crane hooks or compatibility with additional rigging hardware like shackles .

Key Features:

1. Material & Construction:
   • Constructed from quenched and tempered alloy steel (Grade 80/G80), ensuring exceptional tensile strength and resistance to fatigue .
   • Available in both forged and welded variants, with options for flat surfaces (on request) to interface with Omega links .
2. Load Capacity:
   • Working Load Limits (WLL) range from 1.6 tonnes to 56 tonnes, depending on size (e.g., 7-6 mm to 40-36 mm chain diameters) .
   • Proof tested at 2.5 times the WLL and designed with a 4:1/6:1 safety factor for chain slings .
3. Durability:
   • Powder-coated or hot-dip galvanized finishes protect against corrosion, making it suitable for marine, industrial, and outdoor environments .
   • Permanent markings on the body indicate size, WLL, grade, CE certification, and batch number for traceability .
4. Applications:
   • Ideal for multi-legged sling assemblies, load securing, and as a pick point in overhead lifting operations .
   • Commonly used in construction, mining, shipyards, and aquaculture mooring systems .

   • Meets EN 1677-4/DIN 5688-3 standards, ensuring compliance with strict European safety protocols .
3. Can the A343 Master Link be used with different sling types?
   Yes. It is compatible with:
   • G80 chain slings (per EN 818-4) .
   • Wire rope slings (refer to DIN 3088) and synthetic slings (per EN 1492-1) .
4. What environmental conditions can the A343 withstand?
   • Corrosion Resistance: Powder-coated or galvanized finishes protect against saltwater, chemicals, and harsh weather .
   • Temperature Range: Suitable for -20°C to +200°C, though extreme heat may reduce load capacity .
5. How should the A343 Master Link be installed?
   • Proper Alignment: Ensure the link is free of kinks and aligned with the load path.
   • Torque Requirements: Follow manufacturer guidelines for bolt tightening (if applicable) .
   • Professional Assembly: Sling setups should be done by certified personnel to avoid misuse .
6. What maintenance is required for the A343 Master Link?
