Aramco Notes | Rigger Level 3

Wire rope slings are the workhorses of lifting. Riggers must inspect them before every shift.

Reject if the throat opening is increased by more than 15%, or if the hook body is twisted more than 10 degrees from the unbent plane. Latches must engage fully. 3. Hitches and Sling Angles

Aramco’s GI 7.029 provides specific rules for rigging hardware. Your notes should highlight requirements such as: rigger level 3 aramco notes

Understand how the angle of slings affects their capacity. Smaller angles (closer to horizontal) increase tension on the slings.

According to Saudi Aramco’s Safety Management System (SMS) and GI (General Instruction) 7.1, a Rigger Level 3 is authorized to handle complex, multi-crane lifts, critical picks, and load calculations that exceed standard chart values. While a Level 2 knows how to tie a knot, a Level 3 knows why the knot fails under specific angles. Wire rope slings are the workhorses of lifting

At the end of the course, candidates are prepared to lead rigging teams, create detailed lift plans, and ensure safe working conditions throughout operations.
