  1. Shipbreaking Module 4: Heavy Equipment & Material Movement 4.2 Winch rig, Cables, Hooks, & Clamps Susan Harwood Grant Number SH-17820-08-60-F-23

  3. Objectives • Recognize the difference between slings, gear, and rigging • Describe inspection and documentation of gear • Describe winch operations and safety concerns

  4. Rigging and gear is just as important as the equipment itself. Figure 1 Crane moving section around the yard

  5. Gear is the working part of the operations that constantly comes in contact with the material and hoist. Figure 2 Cargo boom and rigging on vessel

  6. There should be a regular visual and documented inspection on all working gear and rigging. Figure 3 Block and with suspended load

  7. Inspectsyntheticandnatural rope and slings for abrasions, wear, and cuts. Figure 4 Natural and synthetic rope

  8. Knots can not replace splices and clamps must be designed for the application. Figure 5 Knots in the mooring line

  9. Wire rope and slings become damaged by kinks, crushing, and overloading. Figure 6 Close up view of wire rope and corrosion

  10. When putting eyes in wire rope check the chart to ensure that a sufficient number of clamps are used and facing properly. Figure 7 Crane moving rigging and slings into position

  11. Common phase: “Never saddle a dead horse” Figure 8 Bridle properly made up during hoist

  12. Remove wire rope from service if damage is observed from heat, deformity, or corrosion. Figure 9 Wire rope close up view of damage and corrosion

  13. Hooks have to be replaced if the opening is more than 15 percent of the original diameter. Figure 10 Hook with proper mousing

  14. Chains must be visually inspected prior to being used. Figure 11 Chain and shackles on pallets in the yard

  15. Chains and slings must be thoroughly inspected every three months and tagged. Written documentation must be kept. Figure 12 Used wire rope being surveyed

  16. Removechains and slings if there is evidence of being stretched,kinked, bentor twisted in any fashion. Figure 13 Chains and rigging removed from the vessel

  17. Do not shorten chain by means of bolting, wiring, or knotting. Figure 14 Chain shorted by use of screw pin shackles

  18. Do not use any gear or rigging that is questionable. Report immediately to the supervisor. Figure 15 Three cranes and rigging suspended

  19. The winch is the work horse of the operation. Figure 16 Slip area near the winch

  20. As the vessel is being lightened the winch continues pulling the vessel to the bank. Figure 17 Winch secured to the hull

  21. Potential problems are centered around personnel getting crushed in the moving parts of the rigging. Figure 18 Workers performing hot work on the bow area

  22. Failure of the rigging can severely injure or cause death by gear snappingback after failure. Figure 19 Head block aligned

  23. When making the connection to the vessel ensure that workers have been briefed and minimize workers in the area. Figure 20 Close up view of attachment point

  24. Watch overhead as the crane moves the rigging in place and that personnel have the appropriate PPE. Figure 21 View from the cargo hold to the winch area

  25. The supervisor must carefully watch the operation and look for safety violations or problems with the rigging. Figure 22 Winch at the head of the slip

  26. Priorto operating the winch checkthe rigging foralignment, proper connections, and personnel are clear of the area. Figure 23 Cables are aligned with the winch and block

  27. During hauling in watch the rigging from a safe distance, for overloading or problems. Figure 24 Rigging in alignment and under static load

  28. Afterthe operation is completed blockthe rigging in place and securethewinch. Figure 25 Winch secured with brake applied

  29. Action Discussion What are the potential affects if the winch is improperly used?
