Description
This spreadsheet designs pinned connection lifting lugs per ASME BTH-1, the standard for below-the-hook lifting devices. It evaluates pin bearing, shear tear-out, and plate net section tensile capacity under the design lift load. Key inputs include lug plate geometry, pin diameter, material yield strength, and rated capacity. Key outputs include bearing stress, shear stress, net section tensile stress, and unity checks. Targeted at mechanical engineers, EPC contractors, and rigging equipment fabricators. Editable Excel format. Engineering support available — contact 3D-LABS.
