Rigging and Hoisting PP.ppt
- 2. The Rigging Plan Properplanning includes: • Identifying information • Written description of operation – FLHA, Pre-Job/Tailgate • Drawings or sketches • People involved • Communication methods • Load characteristics.
- 3. Load Characteristics • Determineconnection used • Center of gravity (CG) below hook.
- 4. Equipment Requirements • Determinesafe working load • Working load limit (WLL) of sling • Hardware attachments • Sling angles between 60 and 90 degrees • Hoisting devices.
- 5. Environmental Factors • Riggingplan notes unusual conditions • Examine surrounding area. – Identify swing radius and hazard zones
- 6. Inspection Requirements • Whennew • Competent person to inspect • Qualified rigger • Inspect each time lift completed • Don't use if in doubt!
- 7. Inspect Wire Rope •Damage or distortion • Excessive stretching • Splicing • Thimbles • Length in service.
- 8. Inspect Synthetic Webbing •Burns • Melting or charring • Snags, punctures, tears or cuts • Knots • Abrasive wear • Missing, broken or worn stitches • Check fittings.
- 9. Inspect Hardware Attachments • Inspecthook • Inspect shackle • Replace if damaged • Shackle pin.
- 10. Inspect Assembled Rigging • Inspectbefore lifting • Match rigging plan • Sling attached correctly • Check sling legs • Pad sharp edges.
- 11. Lift Preparation • Worksiteinspection – Survey swing radius of the load and ribbon/barricade off hazardous zones • Lift equipment inspection – Complete pre-use inspection and remove and tag any equipment that fails. • Rigging gear inspection. – Complete pre-use inspection and remove and tag any gear that fails inspections
- 12. Lifting the Load •Lift test • Actual lifting.
- 13. Lift Safety • Commoncauses of accidents – Not identifying swing zones – Not barricading lifting zone – Not using tag lines • Safe operating practices.
- 14. Sling Care andUse • Carry slings • Remove gear from area • Inspect before and after lift • Maintenance.
- 15. Wire Rope Maintenance andStorage • Clean, dry, handled properly • Kinking • Bird caging • Outdoor storage • Rigging attachments.
- 16. Synthetic Webbing Maintenance • Wash,hang dry • Chemicals – do not use degreaser • Moisture, heat, direct sunlight • Exposure – sun exposure will damage webbing • Keep off floor.
- 17. Summary • Rigging plan– FLHA & PJSM • Choose right equipment • Inspect carefully • Prepare for lift • Lift test • Lift safety • Maintain equipment.
