Below-the-Hook Rigging
Rigging is a precision science where mathematical calculations, physics, and gear selection directly determine the safety of a lift. This foundational course delivers the essential training required to execute controlled, safe below-the-hook lifting operations across various industrial jobsites. From determining load weights and centers of gravity to evaluating sling angles, hitch configurations, and hardware limits, this course removes guesswork from material handling. Learn how to systematically inspect gear, calculate increased sling tension, establish drop-zone boundaries, and maintain full control of suspended loads from ground setup to final placement.
By: Safety LMS | Format: Online | Duration: 3 hours | Certification: 24 Months | Language: EnglishWhat you'll learn
-
Evaluate Load Characteristics: Calculate total load weight, locate centers of gravity, and determine safe rigging attachment points.
-
Select Below-the-Hook Hardware: Choose the correct slings, shackles, spreader beams, and lifting devices for specific materials.
-
Account for Sling Angle Factors: Understand how horizontal sling angles increase load tension and reduce working load limits (WLL).
-
Inspect Rigging Gear: Identify wear, deformation, cut strands, chemical damage, or missing capacity tags before making a lift.
-
Maintain Load Control: Use tag lines and balanced hitch setups to prevent load rotation, shifting, or unexpected movement.
-
Execute Stop Work Actions: Immediately pause lifting operations when equipment damage, line-of-fire hazards, poor weather, or signal confusion occurs.
Description
"Once a load leaves the ground, your rigging choices are set in stone. Calculating tension, inspecting hardware, and respecting fall zones ensures every suspended load reaches its destination safely."
Whether you are attaching slings as an qualified rigger or coordinating lifts on the ground, this training gives you the technical confidence, safety mindset, and practical skills needed to keep material handling operations safe, controlled, and compliant.
