Professional riggers utilize a specialized arsenal of below-the-hook lifting hardware to safely secure, stabilize, and manipulate heavy loads. The foundational tools include various lifting slings—wire rope for versatility, synthetic web for fragile loads, and alloy steel chain for high-temperature or abrasive conditions. Connecting these slings to the load and crane hook commonly uses forged steel shackles and master links. Turnbuckles are used for tensioning and load leveling.
For load stabilization and weight distribution, riggers employ spreader bars and lifting beams to prevent crushing forces on the cargo. Precision positioning is achieved using manual chain hoists, lever hoists (come-alongs), hydraulic jacks, and machinery rollers.
Communication is maintained via two-way radios, while standard tag lines are used to control load spin. Critically, every piece of rigging hardware must be rated, marked with its WLL or size/grade (depending on the component type), and inspected in strict compliance with applicable OSHA and ASME B30 standards to prevent catastrophic failure.
