  1. Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23

  2. Disclaimer • This material was produced under grant number SH-17820-08-60-F-23 from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or polices of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.

  3. Objectives • Describe hoist and gear operations • Identify the inspection protocols • List the types of equipment used • Explain hoisting series • List emergency type situations

  4. Hoist and Gear Operations

  5. Cranes and heavy material moving equipment are extremelyimportant to the operations of ship breaking. Figure 1 Crane hoisting line and vessels rigging

  6. Without it shipbreaking would be extremely labor intensive and unsafe. Figure 2 Hoisting sectional to shore via crane

  7. But with the usage of the equipment comes safety concerns that can result in injury and death. Figure 3 Exploration rig on barge awaiting to be dismantled

  8. There are many components that go into hoisting operations which increases the chances for systems to fail. Figure 4 Crane along side of slip hoisting

  9. Before the hoist takes place check to ensure proper rigging and that the rigging is laid out safely. Figure 5 Rigging properly laid out and trimmed evenly

  10. The loads should never be moved over personnel. Figure 6 20 ton Steel coils being off loaded

  11. The supervisor, on the vessel, is initially in charge of the hoist and gives the crane operator the only crane signals. Figure 7 Supervisor monitoring final cut before hoisting section

  12. As the load is being put under tension keep clearof the rigging and material. Figure 8 Load clearing side of vessel

  13. Common mistakes are inadequate rigging and placement. Figure 9 Workers securing rigging with gear

  14. The connection of gear to the equipment is just as important as the load connection. Figure 10 Crane conducting hoist off superstructure

  15. The crane operator does not generally have a clear view of operations that are ongoing on the deck of the vessel. Figure 11 Supervisor monitoring hoisting

  16. Before the hoist, all personnel must be clear of the area and other equipment moved to a safe location. Figure 12 Worker removing the rigging after hoist

  17. Personnel can be caught between the hoist and that is why the supervisor must be accountable for all personnel. Figure 13 Crane signalman giving directions to crane operator

  18. During the hoist the on deck supervisor will monitor the hoist and give directions to the crane operator. Figure 14 Crane operator at the controls awaiting for directions

  19. The only time personnel are allowed to approach the hoist is at the direction of the on deck supervisor. Figure 15 Crane moving into position for hoist

  20. Shock loading the hoist is prohibited and dangerous to the load, equipment, and personnel in the area. Figure 16 Crane hoisting section slowly

  21. The transfer point when the hoist is clear of the vessel is when the crane operator takes charge of the hoist. Figure 17 Crane moving section to bank

  22. Workers are not allowed to ride the hoist at any time during the operations. Figure 18 Section being hoisted to yard

  23. Inspections

  24. The hoisting gear must be inspected regularly and prior to each use. Figure 19 Double cranes along vessel

  25. Theinspectionhas to be completed during eachshift change andfrequent intervalsduring the operation. Figure 20 Hoist suspended awaiting to be placed in the yard

  26. Defectivehoisting gear must be immediately reported to the supervisor andremovedfromserviceuntil repaired or replaced. Figure 21 Close up view of chain and shackles

  27. Verifythesafe working load of the gear for operations that will take place during the shift. Figure 22 Safe working load stenciled on spreader bar

  28. Types of Equipment

  29. Crawler cranes Figure 23 Crane

  30. Crane shear Figure 24 Shear on bank

  31. Crane magnet Figure 25 Magnet crane moving steel plates

  32. Skid loader Figure 26 Skid loader moving materials on deck

  33. Skid loader with hydraulic hammer Figure 27 Skid loader with concrete hammer

  34. Wheeled forklift Figure 28 Forklift moving steel pieces

  35. Crane with clam bucket Figure 29 Crane stacking processed steel

  36. Hoisting Series

  37. Hoisting Series • The following photos are various materials that are being hoisted from the vessel to shore. • Discuss the operations and view points of the evolution. • The angle shown is generally what you do not observe.
