EOT Crane Preliminary Sizing Calculator

EOT Crane Sizing Calculator

⚠️ ENGINEERING DISCLAIMER: This tool is intended for educational and preliminary estimation purposes only. It does not perform full fatigue life calculations, localized structural buckling checks, or dynamic cross-travel calculations. Actual construction metrics must be verified by a certified professional engineer according to active standards (FEM, IS, CMAA).
