  6. Objective 2: Match rigging terms to the correct definition as used in TSP721 What is the meaning?

  7. RIGGING Used either singularly or in combination to attach a load to a lifting device for the purpose of stabilizing, lifting, pulling, or moving a suspended load.

  8. OVERHEAD LIFTING The process of lifting which would elevate a freely suspended load to such a position that dropping the load would present a possibility of bodily injury or property damage.

  9. OVERHEAD HANDLING SYSTEM A system comprised of all load bearing components used to lift the load, including the crane or hoist, the lifting device, and the interfacing load lift points

  10. REDUNDANT LIFT • Performed multiple times • Uses same hook and rigging • May involve different personnel during execution

  11. REPETITIVE LIFT • Performed multiple times • Uses same hook and rigging • Must use same personnel during execution

  12. INTERMEDIATE HOIST A hoist placed between the load and hook of the overhead handling equipment, or in series with a sling used to lift a load

  13. LIFTING DEVICE Any hardware used to suspend an object from a crane or hoist hook

  14. RIGGING LIMITED CAPACITY AS CONFIGURED • The component of a rigging system that has the lowest capacity or weakest link as rigged. • Subject to hardware size, its WLL, angle the load is applied, and number of load lift points.

  15. BELOW THE HOOK (BTH) LIFTING DEVICE Any fabricated assembly designed to attach a load to a hoist mechanism that is used to transport the load by suspending or lowering

  16. Objective 3: State the individual roles and responsibilities required of persons involved in rigging and rigging support activities at TVA sites.

  17. RIGGING PROGRAM COORDINATOR • Ensures lifting & rigging conforms to the TVA Rigging Handbook • Helps in development of training & qualification of all riggers • Helps develop rigging plans • Provides oversight

  18. SUPERVISOR/FOREMAN • Ensures riggers are qualified & proficient • Ensures vendors & supplemental workers are qualified • Ensures personnel under their supervision perform rigging by procedure

  19. PERSON IN CHARGE • Qualified rigger • Responsible for safe conduct of rigging portion of lift • Determines load path & lay-down area prior to lift • Ensures personnel are not positioned between load & objects

  20. RIGGING AND RIGGER CLASSIFICATIONS • RIGGING • CLASSIFICATIONS • NORMAL • COMPLEX • RIGGER • CLASSIFICATIONS • BASIC • ADVANCED

  21. BASIC RIGGER • Develops normal rigging plans • Obtains weights & CGs • Understands limits of rigging • Understands requirements for lifting • Complies with plant/site load path requirements • Inspects rigging • Uses only approved rigging • Maintains housekeeping

  22. ADVANCED RIGGER

  23. SIGNAL PERSON Must be a qualified rigger

  24. SIGNAL PERSON Signal Person's duty: Only responsibility is to flag, monitor & position load. Person in Charge may perform Signal Person duties if…….

  25. SIGNAL PERSON Optional for lifts with verbal communication using: • Pendant cranes • Radio control cranes • Chain falls • Come-a-longs • Winch • Hoist • Forklift attachment • Block and tackle

  26. ENGINEERING • Approves rigging for temporary structural supports • Provides input/approval on rigging plans when requested

  27. TOOL ROOM/RIGGING STORAGE ATTENDANTS (AS APPLICABLE) • Trained & qualified to inspect rigging • Issues rigging only to qualified riggers • Ensures no defective rigging is issued • Removes, tags, & segregates all defective rigging

  28. GENERAL RESPONSIBLITIES (MANAGEMENT EXPECTATIONS FOR ALL LIFTS) • TVA qualified rigger will direct each rigging activity • Everyone involved will attend a pre-job briefing • Only rigging with current annual inspection will be used • Qualified rigger will inspect all rigging prior to and after each lift • Inspect as necessary during use

  29. GENERAL RESPONSIBLITIES (MANAGEMENT EXPECTATIONS FOR ALL LIFTS) • Use only established & approved rigging practices (TSP 721A) • Use only rigging purchased in accordance with ASME B30 standards or fabricated under TVA approved specs. • Do not alter unless approved by engineering TVA RIGGING HANDBOOK TSP 721A

  30. GENERAL RESPONSIBLITIES (MANAGEMENT EXPECTATIONS FOR ALL LIFTS) • Determine accurate load weight prior to lift • Verify weight with load cell if necessary • Load must be free prior to being rigged for a lift (may use load cell) • Protect slings from sharp edges of their loads • Use “two minute rule” by completing the rigging card prior to making the lift Dynamometer • ?

  31. GENERAL RESPONSIBLITIES (MANAGEMENT EXPECTATIONS FOR ALL LIFTS) • Qualified Rigger: • Maintain housekeeping of rigging equipment after obtaining it and; • Prior to returning it to tool room or storage area • Inspect all rigging prior to, during, and after use • Return to proper storage after the job is completed

  32. RIGGING USED FOR TEMPORARY STRUCTURAL SUPPORT . . . . . . . . . . . . . .

  33. Objective 4: Identify the two rigging classifications and state the criteria used for their classifications. COMPLEX NORMAL

  34. NORMAL RIGGING Lift must include all attributes • Known center of gravity • Load attachment points above center of gravity • Sling angle greater than 45° above horizontal • Single hook • Drift angle equal to or less than 15° • Load weight less than 40,000 pounds

  35. COMPLEX RIGGING Lift only needs to meet one or more attributes • Unknown center of gravity or center of gravity is 12” or more off geometric center in any direction • Load attachment points below center of gravity • Sling angle less than 45° above horizontal • More than one hook from overhead handling equipment • Drift angle greater than 15° • Load weight equal to or greater than 40,000 pounds

  36. Objective 5: Identify what type rigging planning is required, the criteria for planning, and who is responsible for planning and approval.

  37. NORMAL RIGGING PLANS • All lifts require some form of planning • No documentation required for normal rigging (exception: when engineering assists) • TVA rigging card is required for all lifts

  38. TVA FORM 20403 RIGGING PLAN USE REQUIREMENTS • Complex rigging • Any rigging requiring engineering assistance • Any other lift where a written lift plan has been deemed necessary TVA 20403 Exception: If the lift is covered by a site procedure, a vendor drawing, engineering design output, or by the TVA Rigging Manual, then Form TVA Form 20403 is not required.

  39. TVA FORM 20403, RIGGING PLAN USE REQUIRED FOR THESE HITCHES SINGLE INVERTED BASKET DOUBLE INVERTED BASKET DOUBLE CHOKER EYES UP TWO SINGLE BASKETS The use of any of these hitches or any hitch not shown in TABLE A-33 of TSP721A

  40. TVA 20403 RIGGING PLAN COMPLETION & APPROVAL • COMPLEX RIGGING LIFTS • Initiation- Basic or Advanced Rigger • Approval- Advanced Rigger or designated qualified person • NORMAL RIGGING LIFTS • Initiation • Approval - Basic Rigger

  41. TVA RIGGING CARD USE • Required for every rigging job • Enforces stop, think, act and review before performing lift • No substitute for form TVA 20403 (Rigging Plan) • Completed in field prior to lifting load • Maintained at lift location during lift • Completed after rigging installation & ready to make lift • Person-in-Charge signs prior to making lift • Any block marked no requires concurrence

  42. TVA RIGGING CARD USE (CONTINUED) • • Used for redundant lifts if attributes re-verified by PIC • If so, use reverse side of card • If attributes change- new card required • Repetitive lifts by same crew may use same card without re-verification • Electronic versions or duplicates permitted

  43. Objective 6: State the required controls for working near or in the load drop zone (LDZ)

  44. LOAD DROP ZONE (LDZ) AREA D • Area that if load falls would cause injury • Area unless defined in JSA, procedure, or boundary controls = • Height of object + distance raised up to max. of 10 feet. • Continuously around object • For objects greater than 10 feet= radius of 10 feet + height of object H D+H D+H LOAD DROP ZONE LIFTS LESS THAN 10’ OFF FLOOR D 10’OR GREATER D+10’ D+10’ LOAD DROP ZONE LIFTS GREATER THAN 10’ OFF FLOOR D= HEIGHT OF THE OBJECT H= HEIGHT OBJECT IS RAISED

  45. LOAD DROP ZONE (LDZ) REQUIREMENTS • Personnel remain outside LDZ • Permission to enter required from Person in Charge (PIC) • Prior to lift: • Verify clear unobstructed load path & ingress/egress path • LDZ boundary monitoring • No one allowed under load

  46. PRE- JOB BRIEFINGS (PJB) Pre-Job Briefing items to discuss: TVA SPP-18.005 Rigging plan Specific assignments Communication methods LDZ size & control Safe egress Load control Load positioning Emergency stop signal Location of power disconnects Contingencies

  47. LOAD CONTROL WITH TAG LINE • Preferred method of load control • Discuss in PJB • Long enough to clear LDZ • Never wrap around body • Attach far from C.G. as possible • Trail the load • Use shepherd’s hook or similar device to reach tag line or adjust cribbing

  48. EMPLOYEE GUIDING A SUSPENDING A LOAD Person can assist guiding in place with hands if the following are met: Tag line ineffective Load is chest high or less No risk of being struck by load Hazards identified preventing tripping, falling under load Hand & body part hazards for pinch points evaluated & eliminated Discuss in PJB
