The spreadsheet verifies some configurations of lifting lugs and padeyes.

Lifting beams, Lifting frames and Lifting spreaders are a means of providing two or more lifting points from the hook of the lifting machine or crane spaced so as to match the position of the lifting points on the load. The difference lies in the way the forces are transmitted. A lifting beam is loaded in bending.

Different worksheets are reported for a complete verification of common configurations.

'Design and Construction of Lifting Beams' by David T. Ricker Per AISC 13th Edition ASD Manual, ASME BTH-1-2008, and Tensile Strength of Lifting Lug (ASME Eqn. Lifting Lug - Analysis of lifting lugs per 13th Ed. AISC Manual (ASD) and Reference #1a & b Program Assumptions and Limitations: 1. The following references were used in the development of this program.

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.
