INTRODUCTION & SCOPE OF WORKThe following calculations are performed to verifiy the design of a lifting lug (Padeye) for use in temporary works such as shop lifts and movements of equipment during construction and handling of equipment prior to it's service life. Note: Padeyes for service / operational use may require additional design checks depending on the nature of the service and the particular design codes applicable for the project. The following calculations are carried out in accordance with EC3 allowable stress limits and assumes onshore controlled lifting in plane with the padeye using Crosby 2130 or Green Pin shackles.This calculation does not include checks for the local area capacity under the padeye.
DESIGN CODES & REFERENCESEurocode 3 Structural SteelworkEN: 13889:2003 Forged Steel Shackles for General Lifting Purpose
SUMMARY OF RESULTS8 (eight) Padeyes have been checked and shown to be acceptable for the SWL capacities stated, these are:
