Nobledenton Guidelines for Marine Lifting and Lowering Operations 0027/ND. CALCULATION SHEET Job Number: Sheet 1 of Customer: Revision: 1 Date: Project: Title: Lifting Lug Design By: P.O. Stress Check for Base Weld (Tensile, Bending, Shear, Total Stress)ĥ. This supporting document details calculations for the proper design of a lifting beam and redesigned lifting lugs for the 241AZ01A decant pump. Stress check for Base Plate (Tensile, Bending, Shear, Von Mises and Combined)Ĥ. Stress Check for Pin Hole (Tensile, Bearing, Shear, Hertz stress)ģ. See the instructions within the documentation for more details on performing this analysis. This calculator follows the Air Force Method as documented in the Stress Analysis Manual of the Air Force Flight Dynamics Laboratory (FDL). Geometry check: Main plate radius, Shackle clearancesĢ. The Lug Analysis calculator allows for analysis of lifting lugs under axial, transverse, or oblique loading. It rigorously calculates all the stresses coming onto the pad-eye, viz.ġ. It can also be used to verify an existing pad-eye for sling loads.Ī simple pad-eye without brackets, and with one cheek plate can be designed/tested.Ī video demonstration of the spreadsheet is here: ![]() The password Pa55word may be used to unlock spreadsheets. Phillip Rennie: 2018 07: Material Take Off Rev 0.2: Cut paste and add the approprate cells, to form a clean clear MTO. This excel spreadsheet helps design a pad-eye for Lifting or Marine Transport Operations/Lashing design. Lifting Lug Stress Design (ASD) Design Checks lift lug sizes for 4 point lifts.
