  1. MAIN 220 Industrial Rigging Chris Miller

  2. Wire Rope / Slings • Objectives • Know difference between Wire and Rope Slings • Know definitions of rigging principals

  3. Wire Rope • Classification • # strands • # of wires per strand • Wire Strength • IPS • EIP • EEIP FOR MORE INFO... TCP TRAINING Preparing The Site (319)

  4. Factors Affecting Wire-rope • Bending • Sharp Corners • Angles of Force • Temperature • Heating • Corrosion and environment

  5. Sling Components • P. 36 p. 37 and p. 41 • Sling attachments • Where Used • Wear • Performance Issues FOR MORE INFO... TCP Equipment Installation Lesson 2,3,4 (318)

  6. Fiber Rope and Webbing Slings • Fiber Natural • Manila, boat rope • Grades 1-3 • P.51 • Synthetic • Nylon • Polyester • Polypropylene • Benefits • Length of fiber

  7. Factors Affecting Fiber-Ropes • Sharp Bends • Temperature • Moisture • Chemical Active Environments • Fittings and Splices

  8. Fiber Rope and Webbing Slings • Load Capacity for fibers • P. 57 color codes • Inspecting ropes • Heat damage • Apparent decomposing • Excessive wear • Worn Stitching • Cuts Tears Punctures • Distortion

  9. Industrial Hoists and Cranes • Lesson 5 Chain Hoist • P. 67 picture • Hook-Suspended • Trolley-Suspended • Overhead powered • Single reeving • Double reeving Safety overloading Limit Switches

  10. 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

  11. 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

  12. 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

  13. 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

  14. Scaffolds and Ladders • Eyebolts and Ratings • P. 92 picture • Lean against the wall
