Hi!
www.thenavalarch.com launches the pad-eye design spreadsheet
This excel spreadsheet helps design a pad-eye for Lifting or Marine Transport Operations/Lashing design. It can also be used to verify an existing pad-eye for sling loads.
A simple pad-eye without brackets, and with one cheek plate can be designed/tested.
A video demonstration of the spreadsheet is here:
It rigorously calculates all the stresses coming onto the pad-eye, viz.
-
Geometry check: Main plate radius, Shackle clearances
-
Stress Check for Pin Hole (Tensile, Bearing, Shear, Hertz stress)
-
Stress check for Base Plate (Tensile, Bending, Shear, Von Mises and Combined)
-
Stress Check for Base Weld (Tensile, Bending, Shear, Total Stress)
-
Shear Stress Check for Cheek Plate Weld
Immensely useful for Marine Operations. It is based on the standard references:
AISC ASD
API RP 2A WSD
Nobledenton Guidelines for Marine Lifting and Lowering Operations 0027/ND.
