Design of Lifting Lugs Are the provisions of AISC 360-10 Section D5 appropri-ate to use in the design of lifting lugs? Not really. There are other provisions that are more suitable to this application. AISC 360 Section D5 is intended for connections of tension members within buildings. Traditionally the provisions were intended to be used with trusses, and the Johnston research upon which they

Sparta's approach to optimizing the spreader bar design (otherwise known as lifting bar or lifting beam) is an iterative process. Variations in the design of the multi-lift spreader bar evolve over a period of time as requirements and technology change and the demand for a more efficient product is desired..

The Lifting Lug Design spreadsheet will be validated using an example provided in the Stress Analysis Manual [1], it shows a double joint lug (female and male lug with pin) with an axial load..

design weight which can be used in subsequent design Quite often it is desired to modify the existing lifting calculations. The resulting factor of safety is beams by adding reinforcing or changing the lifting lugs. If approximately 5. welding is required, it is recommended that low hydrogen 4. Calculate the forces for the governing factored design electrodes be used in case the beams are made. The various lugs were evaluated for compliance with the ASME BTH-1 “Design of Below-the- Hook Lifting Devices”, 2014 edition. In order to determine the load limit for each category and.

"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
