Rigger Level 3 Aramco Notes Site

Ensure the pin matches the shackle body exactly; never use a generic bolt as a shackle pin. 3. Hitch Types and Capacities

A load will always shift until its Center of Gravity is directly beneath the hoist hook.

The certification exam is proctored by a third-party assessor (often or Worley ) on behalf of Aramco. The pass mark is 85% – harder than typical trade exams.

Both arms extended horizontally, palms down, move arms rapidly back and forth. 7. Exam Day Tips and Checklist

These are the "holy grail" documents you need to reference for your notes. They are the source material for most exam questions: rigger level 3 aramco notes

If the hook is not positioned directly over the CG before lifting, the load will swing wildly when lifted off the ground.

To pass the certification exam, you must be proficient in the following technical areas:

Even though the load is 4,000 kg, each sling must be rated for at least 3,000 kg (not 2,000 kg) due to the angle. 5. Center of Gravity (CG) and Stability

Both arms extended horizontally, hands open, move arms rapidly back and forth. Note: Anyone on an Aramco site can give the Emergency Stop signal, and the operator must obey it immediately. 7. High-Yield Aramco Exam Tips Ensure the pin matches the shackle body exactly;

Approximately 7,850 kg/m³ (or 490 lbs/ft³).

Tag lines must be made of non-conductive material (typically manila or polypropylene rope).

The (Rigger III) certification is a foundational credential required for personnel performing basic rigging and lifting tasks within Aramco facilities. A Rigger III typically handles standard loads up to 10 tons under direct supervision, focusing on equipment inspection, safe hitching, and clear communication with crane operators.
