Pad Eye Design Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Designs pad eyes — the circular-plate lifting attachments welded to decks, beams, skids, and equipment. Checks every failure mode a lifting pad eye must pass: pin bearing, plate shear, net section, hoop tension, and weld capacity.
What’s Inside the Excel File
- Inputs — plate thickness, plate diameter, hole diameter, pin diameter, cheek plates if any, weld type and size, design lift load with dynamic factor
- Pin bearing on plate and cheek plates
- Net section tension at pin hole
- Plate shear at hole
- Hoop tension in plate ring around hole
- Weld capacity at pad eye to base
- Governing failure mode with utilization
Who This Is For
- Lifting and rigging engineers
- Skid and module fabricators
- Offshore and Oil & Gas lift planners
- EPC project teams specifying lifts
Codes & Standards Referenced
- ASME BTH-1 — Below-the-Hook Lifting Devices (design factor approach)
- Industry standard pad eye design methodology

Frequently Asked Questions
Pad eye vs lifting lug?
Pad eye is typically circular plate with single hole. Lifting lug is typically rectangular. Different failure modes — pick by attachment geometry.
