Rigger Level 3

Achieving under the Saudi Aramco classification system is a significant career milestone. It moves you beyond basic signaling and intermediate rigging into the realm of complex lifts, critical lift planning, and crew supervision. The Uneven Leg Problem: Given a 4-leg chain

  1. The Uneven Leg Problem: Given a 4-leg chain sling with one leg that is 2 inches shorter than the others, the candidate must calculate that the short leg takes 60% of the load. The correct answer is to reject the sling, not recalculate.
  2. The Shackle Angle: Many calculate the WLL (Working Load Limit) of a shackle at 90 degrees, but forget that Aramco requires de-rating by 50% when the angle is less than 45 degrees.
  3. The "Dead Man" Lift: Lifting a pipe buried in sand. The notes explicitly state: "If resistance is met, STOP. Do not increase load. Excavate." The exam trick is a question about increasing crane power to free a stuck load—the correct answer is always "No."

Couplers:

The Safe Working Load (SWL) for a right-angle coupler is typically 9.4kn , while an adjustable/swivel coupler is approximately 5.3kn .
