About this file
This document is a Statement of Objectives (SOO) for a rigging training program that establishes fundamental competencies and performance criteria for riggers.
The SOO outlines six fundamental rigging objectives: identifying rigging equipment and usage; performing pre-use inspections of rigging equipment; determining and selecting rigging equipment with knowledge of hitch configurations and load angle factors; attaching rigging configurations and manipulating taglines; understanding load dynamics and associated hazards; and facilitating load security and equipment usage tracking post-movement. Performance criteria specify required knowledge areas including hooks, shackles, links, rings, swivels, slings (chain, wire rope, synthetic, and metal mesh), below-the-hook lifting devices (bridles, spreader bars, equalizer beams, and man baskets), load-securing devices (lever binders, synthetic ratchet straps, and tensors), tag lines, portable hoists (manual, electric, and pneumatic), dunnage/cribbing, sling hitches (vertical, choker, and basket), working load limit (WLL) determination, and sling load calculations. Trainees must understand weakest link concepts, sling angle impacts, hitch angle impacts, and crushing force effects. The SOO establishes inspection knowledge requirements covering initial, frequent, and periodic inspections; Registry of Lifting Appliances (RLA)/Rigging Logs; and rejection criteria for all rigging equipment categories. Practical skill requirements include donning PPE, examining jobsites for hazards, determining load characteristics and measurements, developing rigging configurations, participating in risk assessments, participating in pre-mission briefs, performing pre-use inspections, applying proper rigging configurations, transporting loads with taglines, securing loads at offload locations, and unloading rigging configurations. The document specifies that trainees must attend demonstrations and successfully perform all identified skills under observation.
