Shackle Inspection & Certification in Dhahran
A shackle is a U-shaped forged steel connector closed with a pin, used to join slings, hoist rings, hooks and rigging in lifting, towing and anchoring. Dee and bow patterns, with screw pins or bolt, nut and split pin, are found across Saudi construction, offshore support, marine and oil and gas sites. Shackles are small and often reused without records, so an independent examination that checks the marking, the pin and the body geometry catches worn, bent or mismatched shackles before they reach a critical lift.

Testing
Where required for new, repaired or certified lots, a proof load test is typically applied at around twice the working load limit depending on the standard and client, with magnetic particle inspection added where cracking is suspected.

FAQs
Can you inspect a shackle on site in Dhahran?＋
Yes. Our inspectors travel to your yard or project site in Dhahran, including Aramco Dhahran, KFUPM and Techno Valley, so the equipment does not need to be moved.
Which industries in Dhahran request shackle inspection?＋
Typically operators and contractors in the Eastern Province from these sectors: Oil, Gas & Petrochemical; Construction & Infrastructure.
Can I replace a lost shackle pin with a bolt from the store?＋
No. The pin is a rated part of the shackle, and an ordinary bolt may not match its strength, diameter or fit. Use only the original or manufacturer-supplied pin, or replace the whole shackle.
What does the WLL on a shackle mean?＋
WLL is the working load limit, the maximum load the shackle is designed to carry in normal service when loaded in line, with a safety margin built in. The usable capacity falls if the shackle is side loaded or the sling angle is wide, so check the manufacturer's guidance.
