Description
Skid Lifting Lug Rope-Angle Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Designs lifting lugs on equipment skids accounting for sling rope angle effects. When a 4-point skid is lifted with slings meeting at a single hook point, lug loads are larger than the simple weight/4 calculation because of the inclined sling geometry. This sheet captures that effect properly.
What’s Inside the Excel File
- Inputs — skid weight, CG location, lug positions (4 points typical), sling length, hook height above skid, dynamic factor
- Sling angle calculation at each lug
- Lug load resolution into vertical + horizontal components
- Asymmetric skid handling — uneven load distribution when CG is off-center
- Lug stress checks — net section, pin bearing, shear
- Weld capacity at lug base
Who This Is For
- Skid and module design engineers
- Lifting and rigging engineers
- EPC project teams on modular packages
- Equipment manufacturers shipping skid units
Codes & Standards Referenced
- ASME BTH-1 — Below-the-Hook Lifting Devices
- DNV / Noble Denton lifting philosophy
- Standard rigging geometry mechanics
