WARNINGS/INSTRUCTIONS

  1. Inspect all Padeyes prior to each use for cracks or damage;
  2. Do not exceed the working load limit (WLL) of any Padeye (see WLL Summary Table);
  3. The WLL of each Padeye may be less than the WLL of the shackle used, depending on Category and Class;
  4. In-Line load limit is equal to the shackle WLL for Category A Class 0;
  5. Shackles must be Crosby G-2130, or equivalent;
  6. Shackle pins must be allowed to rotate in the shackle pin holes;
  7. All welding to AWS D1.1 or D14.1;
  8. Do not cold bend the lug;
  9. Do not hammer on the lug;
  10. Do not use for Fall Protection (See 29 CFR §1926.502)
  11. Use the appropriate size shackle pin and capacity to match the lug hole diameter and capacity;
  12. Do not use any undersized shackle pins;
  13. Temperature limit +10 degrees F to 200 degrees F;
  14. Weld only onto acceptable base metal;
  15. Weld only onto a flat surface;
  16. Weld must be on the same surface/plane;
  17. Do not allow out of plane weld returns;
  18. Fillet weld sizes are minimum requirements for WLL;
  19. Show welding symbols on instruction/warning tag;
  20. Ensure base metal thickness and weld size comply with Table 3-3.4.3-1;
  21. The lug and base metal must not exceed the thickness requirements of the thicker part;
  22. Use a qualified welding procedure to weld lug onto equipment;
  23. Welding procedures shall be qualified to meet minimum strengths required per end-user design;
  24. No welding of lugs onto equipment that is stress relieved for environmental reasons or per code, for that alloy, without end-user’s review and approval.

QA/QC PROCEDURES

  1. Sample two (2) lugs or 5% (whichever is greater) of every lot produced for destructive testing;
  2. Perform metallography;
  3. The sample is split down the middle and examined for dendritic structure in middle of material, and excessive flow and cracking at flashing at edge of forging;
  4. After metallography, take both tensile and Charpy tests to confirm it meets A36 specification;
  5. Charpy samples are cut to test for both outer and inner material on lifting lug;
  6. 10-20% of each lot will be magnetic particle tested to look for cracking;
  7. Visual inspection for cracking on all lugs produced.
