#LIFTING LUG DESIGN SPREADSHEET VERIFICATION#
The Part 2 contains the new verification worksheets included in the version 2.0 ( lifting padeyes with stiffening brackets and lugs with overlapping plate joint). Useful graphical views of the geometry of the padeye are foreseen for a better definition of the configuration and dimensioning parameters. stiffening brackets (vertical and bottom sections).Verification of fillet welds of the composed elements:.Verification of the failure modes of the lug hole to:.Calculus and verification of the stresses on the loaded sections due to tension, shear, bending and torsion moments.Forces in the plane of the pad and transversal to it.Evaluation of the safety factors for lifting equipment.The main section parameters (shear sections, bending modulus, inertia moments…) are calculated for the stress analysis Geometry definition and dimensional requirement checks.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). The worksheet verifies a lifting padeye provided with stiffening brackets and cheek plate loaded with a sloped force. ĭesign of a lifting padeye with stiffeners The front and lateral welds are verified considering the EN. The verification of the failure modes and the plate section are included. The previous lug is verified considering the case with the main plate overlapping the bottom structure with a welding line all around its perimeter.įorces in the plane of the pad and transversal to it are considered. Metric (S.I.) or English (U.K.) Units System can be selected for the calculation.ĭesign of a lifting lug with overlapping plate joint subjected to a sloped force

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.Īlso for this case two welding types are included: fillet weld and full penetration weld. Lug with an applied force having an assigned sloped angle and eccentricity with respect to the hole. Lifting Lug subjected to a load with given slop e Metric (S.I.) or English (U.K.) Units System can be selected for the calculation. Useful graphical views of the lug and welding are foreseen to better define the geometry and the dimensioning parameters. Two dimensioning welding cases and configurations:

The verification is performed considering the reference 'Design and Construction of Lifting Beams' David T. However, the refinement of these requirements have necessitated conservative methods of design.ĭifferent worksheets are reported for a complete verification of common configurations. In the past, the lug strength was overdesigned since weight and size requirements were for the most part unrestricted. Lugs are connector-type elements widely used as structural supports for pin connections. 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. Download the study for lifting lug by Kawish Shaikh LiftingLug.xls Pilkey W. Note that this example is very much like the pad eye lug for #25 Presentation, ie, the dimensions are all most. The printout below shows the design for a plate lug without any side load, but it is the basis for calculating the additional stress that a side load imposes on a plate lug and the weld.

#LIFTING LUG DESIGN SPREADSHEET ACTIVATION KEY#
To activate it, unzip the downloaded file, run the application and insert the Activation Key you will find in the. 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. You can download a trial version of this spreadsheet for evaluation purpose.
