Spreader Bar Design Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Designs spreader bars (lifting beams) used between the crane hook and the lifted load to convert inclined slings into vertical lifting points. Critical for delicate loads (vessels, modules, finished equipment) where the inward force from inclined slings would damage the lifted item.
What’s Inside the Excel File
- Inputs — bar length, section properties (W-section, pipe, or HSS), end connection type, design lift load, dynamic factor, lifting geometry above and below
- Compression load in spreader bar from inclined sling geometry
- Slenderness ratio and Euler buckling check
- Combined compression + bending if hook is offset from bar center
- End connection design — lug, pad eye, or shackle attachment
- Self-weight effects on long spreader bars
Who This Is For
- Mechanical and structural lifting engineers
- Heavy lift planners and crane engineers
- EPC project teams on module lifts
- Equipment fabricators providing lift gear
Codes & Standards Referenced
- ASME BTH-1 — Below-the-Hook Lifting Devices
- AISC 360 — column compression methodology
