Every sling used on an Aramco site must have a legible, permanently attached identification tag showing the manufacturer, WLL, and size.
is the vertical height from the hook to the load attachment point. 4. Fundamental Calculations for Rigger Level 3

Increases capacity (ideally 200%, but limited by the hook/hardware). 3. Aramco Safety Regulations & Procedures (GI 7.028)
You are rigging a heat exchanger weighing 22,000 kg. You have two 8-foot wire rope slings (WLL: 15,000 kg each at vertical). The lift points are 3 meters apart. The hook height is 2.5 meters above the lift points. Is this safe? rigger level 3 aramco notes
Aramco utilizes a periodic color-coding system for rigging hardware to verify that equipment has undergone recent safety inspections. Ensure your hardware matches the current site color.
Conducting pre-use inspections of slings, shackles, chains, and hooks, ensuring certification is current.
Any structural deformation that distorts the rope.
Rigging gear is used with specific safety factors (typically 5:1 for general rigging). Never exceed the Safe Working Load (SWL) or Working Load Limit (WLL). C. Common Knots and Hitches Bowline Knot: Used to form a secure loop that won’t slip. Every sling used on an Aramco site must
Saudi Aramco Rigger Level 3 certification focuses on the safe execution of basic rigging tasks, including load weight estimation, equipment inspection, and standard hand signaling. This level typically authorizes riggers to handle loads up to under direct supervision. Core Certification Topics
Uncompromising safety begins with hardware inspection. Aramco inspectors strictly enforce rejection criteria for damaged gear. Wire Rope Slings
Outline the from Level 3 to Level 1 (Slinger to Lift Supervisor).
Obtaining the "Rigger Level 3 Aramco Notes" is not just a piece of paper; it is a validation of your skills through a third party or Aramco-approved assessor. Fundamental Calculations for Rigger Level 3 | Included
Doubles the capacity of the vertical hitch (200%), provided the sling legs remain strictly vertical ( 90∘90 raised to the composed with power to the horizontal). The Impact of Sling Angles
Carry out daily and periodic inspections of lifting gears (slings, shackles, hooks) and verify they have valid third-party certification and correct color coding .
