Grade 80 / Grade 100 Connecting Links / Hammerlocks (2 Tonne to 31.5 Tonne)
Engineered for the fast, secure assembly of Grade 80 and Grade 100 chain slings, these heavy-duty connecting links (commonly known as Hammerlock links) allow field assembly without welding or specialized shop tooling. Designed to handle safe working loads from 2 tonnes up to 31.5 tonnes, they join alloy chains directly to master links, eye hooks, and rigging components with high tensile reliability.
Key Features:
 * Two-Piece Interlocking Body: Features symmetrical drop-forged halves aligned by a center load pin and locked in place with a steel sleeve washer.
 * Tool-Free Field Installation: Easily assembled on-site using a standard hammer and punch to drive the locking pin through the retaining sleeve.
 * High-Tensile Forged Alloy Steel: Quenched and tempered to absorb extreme dynamic shock loads and resist abrasive wear under continuous tension.
 * Full Load Efficiency: Maintains 100\% of the rated working load limit of equivalent Grade 80 / Grade 100 lifting chain sizes.
 * International Safety Compliance: Built, proof-tested, and certified to meet global rigging standards (EN 1677-1 / ASME B30.26).
Applications:
 * Assembling 1-leg, 2-leg, 3-leg, and 4-leg Grade 80 / Grade 100 chain slings
 * Connecting chains directly to master links, sling hooks, grab hooks, and swivel fittings
 * Replacing worn chain sling hardware on job sites, workshops, and shipyards
 * Heavy equipment tie-down, logging, and overhead crane rigging
