Notes:
1. All plates shall be AS/NZS 3678 Grade 250 U.N.O
2. Fabrications contractor to confirm considering lift plan and weight distribution of skid and components
3. Typical lifting arrangements are between 30-60°. 30° represents worst case values.
4. Based on lug orientation on skid. See drawing 61-15542.00-04-D04-0008
