MecaLug Standard version is the least expensive version of the software that allows the user to perform Padeye / lifting lug calculations per ASME BTM-1 “Design of Below-the-Hook Lifting Devices”. Engineers often design structures and equipment for extreme wind, seismic and other loading that may never occur; however, in the case of a lifting lug those extreme loads may very well be.

The Lug Analysis calculator allows for analysis of lifting lugs under axial, transverse, or oblique loading. This calculator follows the Air Force Method as documented in the Stress Analysis Manual of the Air Force Flight Dynamics Laboratory (FDL). See the instructions within the documentation for more details on performing this analysis. Inspection of lifting lugs. Tuesday, 1 October 2019. Basic Lifting Lug Categories. It may be a surprise to learn that lifting lugs are not ‘all the same thing’. First of all, we can clarify the situation by dividing our ‘lifting lugs’ into three groups: Diagram of lifting in relation to lifting lug category.

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.

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.

See video PART 2. (version 2.0)

The Part 2 contains the newverification worksheets included in the version 2.0 (lifting padeyes with stiffening brackets and lugs with overlapping plate joint).

The spreadsheet you will purchase and receive is an excel file compiled in a “.EXE” application file format identified by our icon image. See the Activation/Support page for more details.

Trial version

You can download a trial version of this spreadsheet for evaluation purpose. Click below to download the zipped file.

The trial version has a limited number of runs from its first activation on your computer, after that it stops to work and a new activation key is needed or the full version should be purchased.

To activate it, unzip the downloaded file, run the application and insert the Activation Key you will find in the .TXT file.

After key validation, the runs count starts on your machine and a window is displayed at each launch reminding you the remained launches.

To purchase the full version go back to this webpage or use the “Purchase Online” button on the window.
