Rigger Level 3 Aramco Notes Link

Any lift exceeding 40 tons automatically becomes a Critical Lift and requires a formal, written critical lift plan signed off by a Rigger Level 1.

As the horizontal sling angle decreases, the tension on each sling leg increases exponentially.

Alternatively, you can calculate SAF using physical measurements:

A throat opening increase of more than (or 1/4 inch) from the original dimensions. rigger level 3 aramco notes

T=40002×1.5=2000×1.5=3000 kgcap T equals 4000 over 2 end-fraction cross 1.5 equals 2000 cross 1.5 equals 3000 kg

Must be used on all lifts to control structural rotation and swing. They must be made of non-conductive material (like manila rope) and must never be wrapped around a rigger’s hand or body.

10 randomly distributed broken wires in one rope lay, or 5 broken wires in one strand of one rope lay. Any lift exceeding 40 tons automatically becomes a

Aramco is strict on equipment condition. Know the rejection criteria for:

: Use standardized hand signals to direct crane operators and conduct pre-lift toolbox talks to inform the team of risks. Essential Technical Knowledge

Preparation for the Aramco Rigger III exam requires a deep understanding of the following areas: : T=40002×1

Maintain a minimum clearance of 20 feet (6 meters) from overhead power lines up to 50kV. For higher voltages, increased clearance distances are legally required. 7. Standard Crane Hand Signals

: Perform pre-use inspections on all rigging hardware, including slings, shackles, and hooks, and remove any defective gear from service.

Both arms extended horizontally, move hands rapidly back and forth. Note: Anyone on the job site can give the Emergency Stop signal, and the operator must obey it immediately. Final Exam Preparation Checklist
