Episode 2: Inspection & Testing: How to Ensure Your Rigging is Safe

Daily and periodic inspection of lifting equipment is essential to ensure safety and prevent accidents. This includes checking hooks, shackles, wire ropes, chains, and any other components used in lifting operations.

First: Daily & Periodic Inspections

Daily Inspection	Periodic Inspection
All users must perform a quick visual inspection before each use. Check for cracks, rust, or any visible deformation. Ensure all markings and Working Load Limits (WLL) are clear and readable.	Must be carried out by qualified technicians or supervisors according to a set schedule (monthly – semi-annually – annually). Includes precise measurements, Proof Load Testing, and verification of certificates and compliance.

Second: When to Reject the Equipment (Rejection Criteria)

Any lifting tool must be rejected immediately in the following cases:

• Presence of cracks, deep rust, or excessive wear marks.

• Missing or damaged connections or pins.

• Missing or unclear identification data or load capacity.

• Failing the proof load tests.

• Bent, twisted, or deformed metal parts.

Third: Inspection of Hooks, Shackles, Wire Ropes & Chains

Hooks:

• Ensure hooks are not bent or cracked.

• Check that the latch operates smoothly and locks properly.

• Measure the throat opening and compare it with the original specifications.

Shackles:

• Ensure the body is straight with no bending or distortion.

• Check that the pin rotates smoothly and is free from rust or thread damage.

• Make sure the original pin is used and is properly secured - do not replace with non-certified substitutes.

Wire rope slings:

• Check for broken wires, kinks, or any bird-caging.

• Count the number of broken wires per meter — if the number exceeds the limit, the rope must be discarded.

• Ensure the rope ends are properly secured and clamped.

Chains:

• Inspect the links for stretching, wear, or twisting.

• Make sure there are no unauthorized welds or modifications.

• Check that the chain hangs freely and is not knotted or twisted.

Petrolift Tips:

Remember, inspection does not replace proper training. Train your team to spot damage signs and replace faulty tools immediately.

Always record inspection results in an official logbook and keep them for future reference.
