Scaffold Leg Load Calculator
Load per standard (leg) from platform loading class, bays and lifts.
Standard couplers slip around 6 kN per coupler, frames buckle by lift height — compare this leg load against the SYSTEM rating, and never forget base plates on soleboards.
Formula
Scaffold Leg Load Calculator is a free scaffold load for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Scaffold Leg Load Calculator
Load per standard (leg) from platform loading class, bays and lifts. The calculation implements P_leg = (A_bay × q × n_decks)/4 + self-weight (EN 12811 / IS 4014 scaffolding). Standard couplers slip around 6 kN per coupler, frames buckle by lift height — compare this leg load against the SYSTEM rating, and never forget base plates on soleboards.
How to use Scaffold Leg Load Calculator
- 1Enter Bay area (length × width) in m² (2.4×1.3 m bay ≈ 3.1 m²).
- 2Enter Duty load in kN/m² (Light 0.75 · general 2 · heavy/masonry 3).
- 3Enter Working decks loaded.
