Download the study for lifting lug by Kawish Shaikh LiftingLug.xls Pilkey W. Peterson's Stress Concentration Factors 3 rd Edition Loading kN P = b = Cyclic Loading Design of Below-the-Hook Lifting Devices ASME BTH-1-2008 Reference: Lifting Lug Design Review Report. Design a shear lug plate for a 14-in. Square base plate, subject to a factored axial dead load of 22.5 kips, factored live load of 65 kips, and a factored shear load of 40 kips. The base plate and shear lug have f ya= 36 ksi and f c' = 3 ksi.
The spreadsheet verifies some configurations of lifting lugs and padeyes.
Different worksheets are reported for a complete verification of common configurations.
Lifting Lug subjected to a vertical load
The verification is performed considering the reference 'Design and Construction of Lifting Beams' David T. Ricker, PE, AISC Engineering Journal, Fourth Quarter/1991 and its updating to 2005 AISC Manual of Steel Construction (click here to download it).
Many sections are reported with the dimensioning verifications:
- Geometry definition and requirements check in compliance with the prescriptions reported in the reference document
- Materials definition
- Verification of the failure modes of the lug to:
- Tensile Rupture of Lug,
- Bearing Capacity of Hole,
- Shear Yielding to Edge of Plate,
- Tension Tear Out to Edge of Plate
- Section verification of the lifting lug's plate
- Welding verification between the lug and the bottom plate, using the norm Eurocode 1993-1-8:2005 and NTC 2008.
Two dimensioning welding cases and configurations: - fillet weld
- full penetration weld
Useful graphical views of the lug and welding are foreseen to better define the geometry and the dimensioning parameters.
Metric (S.I.) or English (U.K.) Units System can be selected for the calculation.
Lifting Lug subjected to a load with given slope
Lug with an applied force having an assigned sloped angle and eccentricity with respect to the hole.
Lifting Lug Design Handbook Pdf
The verifications of the previous case are repeated with the additional verifications of the connected bottom section to the bending effect produced by the eccentricity of the force.
Also for this case two welding types are included: fillet weld and full penetration weld.
Metric (S.I.) or English (U.K.) Units System can be selected for the calculation.
Design of a lifting lug with overlapping plate joint subjected to a sloped force
The previous lug is verified considering the case with the main plate overlapping the bottom structure with a welding line all around its perimeter.
Forces in the plane of the pad and transversal to it are considered. The verification of the failure modes and the plate section are included.
The front and lateral welds are verified considering the EN 1993-1-8.
Metric (S.I.) or English (U.K.) Units System can be selected for the calculation.
Design of a lifting padeye with stiffeners
The worksheet verifies a lifting padeye provided with stiffening brackets and cheek plate loaded with a sloped force. The verification takes into account the guidelines in 'Rules for Classification and Construction Industrial Services IV-6-4' Germanischer Lloyd Aktiengesellschaft Edition 2007 (click here to download it).
Many sections are reported with the dimensioning verifications:
- Geometry definition and dimensional requirement checks. Two stiffening brackets can be selected. The main section parameters (shear sections, bending modulus, inertia moments…) are calculated for the stress analysis
- Materials definition
- Evaluation of the safety factors for lifting equipment
- Forces in the plane of the pad and transversal to it
- Calculus and verification of the stresses on the loaded sections due to tension, shear, bending and torsion moments
- Verification of the failure modes of the lug hole to:
- Tensile Rupture of Lug,
- Bearing Capacity of the Hole,
- Shear Yielding to Edge of Plate,
- Tension Tear Out to Edge of Plate
- Verification of fillet welds of the composed elements:
- main plate,
- stiffening brackets (vertical and bottom sections)
- cheek plate
Useful graphical views of the geometry of the padeye are foreseen for a better definition of the configuration and dimensioning parameters.
Metric (S.I.) or English (U.K.) Units System can be selected for the calculation.

Answer to henk: you're probably referring to the message that 32bit is required. It refers to the version of Excel and not of the file. To run the 64 bit file you need the Excel 64 bit and probably you have the 32 bit. So try with the 32 bit version of the file.
Please for any other technical questions use the dedicated email contact form.
Answer to Alan: First of all don't worry all our files are safe and in general there is no problem with antivirus softwares. Anyway because the .EXE applications are not provided with certified digital signature (not yet), there is the possibility that an antivirus software or Windows firewall generates a 'false positive', showing a warning message (or in worst case blocking the file). In this case enter in the preferences of your antivirus software and add the .EXE in its exclusion files list or temporary dactivate the Antivirs. In this way the antivirus allows its execution without problems.
Answer to Chris Nay: The key is in the text file you've downloaded. It activates the file for a limited use.
Description
Program Description:
'LIFTING_LUG' is a spreadsheet program written in MS-Excel for the purpose of analysis of lifting lugs, used in rigging operations. The user can enter a desired factor of safety (most applications, F.S. = 5.0). The program will determine the ultimate strength of the lifting lug based on several checks and will apply the desired factor of safety to the strengths to attain allowable loads for the lifting lug.
This program is a workbook consisting of two (2) worksheets, described as follows:
