This resource provides essential knowledge on wire and fiber rope slings in industrial rigging. It covers key differences between wire and rope slings, definitions of rigging principles, and classified strength ratings (IPS, EIP, EEIP). The guide also addresses factors affecting wire-rope performance, including bending, temperature, and corrosion. Additionally, it discusses sling components, inspecting ropes, and safe practices when operating and maneuvering loads. Proper understanding of these elements is vital to ensure safe and efficient rigging operations.

Principles and Practices • General Practices • Properly Trained • Rigger familiar with equipment • Rigger makes final say on safety • If signaling requires only 1 person in charge • Everyone as say to stop • Before moving determine where it is going • Load is free to move, not fastened to ground • Be sure everyone is clear of area • No shock loading • No riding • Do not move over where people are working • Never Leave suspended • Never work under load unless provisions to support are in place • Keep hands fingers out of the way
Principles and Practices • Sling Operating Practices • Avoid sharp sling angles • Do not pull sling from under a load when load is resting on sling • Do not leave slings on the ground • Slings should be stored properly • Repair or remove damaged slings • Do not hammer metal mesh slings
Principles and Practices • Turning a Load • Most difficult maneuver • Consider all options before moving • Determine center of gravity • Will blocks be required to support load • Can use • One-hook turn • Single-Sling Turn • Two-Hook turn • P.89
Principles and Practices • Eye Bolts • Have pull ratings and must be remembered p.92 • Rigging thought Process • What is done with load • What tools are needed • Is capacity enough and adequate • How can the hook up be • What will happen with path of travel • What will happen once load is lifted • How will load be stored
