Heavy-Duty Grab Hooks (3.15 Tonne to 31.5 Tonne)

Engineered for rigorous material handling, overhead lifting, and heavy cargo securing, these industrial-grade grab hooks are designed to shorten, anchor, or adjust high-tensile transport and lifting chains. Rated for safe working loads ranging from 3.15 tonnes up to 31.5 tonnes, they feature a precision-engineered narrow throat that securely cradles individual chain links without slippage or damage.

Key Features:

* High Working Load Capacity: Forged and quenched alloy steel construction rated across standard industry capacities (3.15t, 5.3t, 8t, 12.5t, 15t, 21.2t, and 31.5t).

* Non-Weakening Link Engagement: Deep, narrow cradle slot supports the chain link evenly, preserving 100% of the chain's rated breaking strength during shortening.

* Safety Latch / Locking Pin (Optional): Available in standard open-throat or safety-latch (cradle/locking) variants to prevent accidental chain disengagement under slack conditions.

* Grade 80 / Grade 100 Compliance: Fully heat-treated alloy steel meeting international lifting standards (EN 1677-1 / ASME B30.10).

* Durable Powder Coating: High-visibility safety finish (powder-coated yellow/red) for corrosion resistance and easy visual inspection on busy job sites.

Applications:

* Chain sling leg length adjustment in overhead crane operations

* Heavy equipment tie-downs on lowbeds and transport trailers

* Towing, rigging, and logging recovery operations

* Industrial lifting in steel mills, construction sites, and maritime ports

Specifications:

* Working Load Limit (WLL): 3.15t to 31.5t

* Connection Options: Clevis Type (Direct chain link mounting) / Eye Type (Shackle or master link mounting)

* Material: Forged Alloy Steel (Grade 80 / Grade 100)

* Safety Factor: 4:1 Proof Tested
