Wind Force on Load — Formwork Table
Drag force and swing risk on a suspended formwork table from wind speed and exposed area.
Flying tables are the textbook wind-sail pick: huge area, light weight, lifted daily on schedule pressure. Most table-crash reports cite wind in the 8–12 m/s band — legal for the crane, lethal for the table. The 10 m/s default limit here reflects common formwork-supplier guidance.
Formula
Note: Rigging and crane decisions are life-safety critical. This calculator is a planning aid — the load chart, sling tags, site lift plan and a qualified lift director govern every real lift.

About Wind Force on Load — Formwork Table
Wind Force on Load — Formwork Table computes the governing relationship F = ½·ρ·v²·Cd·A (ρ = 1.225 kg/m³) live as you type. Flying tables are the textbook wind-sail pick: huge area, light weight, lifted daily on schedule pressure. Most table-crash reports cite wind in the 8–12 m/s band — legal for the crane, lethal for the table. The 10 m/s default limit here reflects common formwork-supplier guidance. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Wind Force on Load — Formwork Table
- 1Enter your values — Wind speed (gust), Exposed area, Drag coefficient Cd, Task wind limit (sensible defaults are pre-filled).
- 2Read the live results: Wind force, As equivalent mass.
- 3Check the "with your numbers" line to see F = ½·ρ·v²·Cd·A (ρ = 1.225 kg/m³) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Wind Force on Load — Formwork Table?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F = ½·ρ·v²·Cd·A (ρ = 1.225 kg/m³) with authoritative sources cited on the page (EN 13001 / EN 14439 — Crane design & tower crane standards; ASCE 7 — Wind load provisions (power-law profiles))
- ✓Flying tables are the textbook wind-sail pick: huge area, light weight, lifted daily on schedule pressure.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the wind force on load — formwork table use?+
It evaluates F = ½·ρ·v²·Cd·A (ρ = 1.225 kg/m³), exactly as published. Sources: EN 13001 / EN 14439 — Crane design & tower crane standards; ASCE 7 — Wind load provisions (power-law profiles). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Flying tables are the textbook wind-sail pick: huge area, light weight, lifted daily on schedule pressure. Rigging and crane decisions are life-safety critical. This calculator is a planning aid — the load chart, sling tags, site lift plan and a qualified lift director govern every real lift.
When is this calculator the right tool for the job?+
Drag force and swing risk on a suspended formwork table from wind speed and exposed area. A free crane load, wind & rigging safety tool. Most table-crash reports cite wind in the 8–12 m/s band — legal for the crane, lethal for the table. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
