Lug Specific Drawings
Shackle Hole Centerline Height (H): Distance from the base of the lug to the center of the shackle hole. For Type 4 lifting lugs, this is the axial distance (see the figure on the General Information tab in the software for more information).
Lug weld height: The measurement of the weld from its lowest point on the side of the lug to the highest point. The total length of the welds on the sides of the lug is 2x the weld height minus 2x the omitted length.
Weld Len. Omitted over head Weld (Lwo): The length along opposite edges of the lifting lug where the weld stops and then restarts to avoid welding over the head to shell seam. This field is only available when 3 or 4 is selected as the "Support Type."
Lug Weld Leg: The fillet weld leg between the lug and the repad or the lug and the host.
