FAQ

Can I use RiggingSense to plan a real rig?

No. It is an educational tool for understanding rigging statics. Real rigs are calculated and signed off by a qualified rigger or structural engineer against manufacturer data and the applicable standards. The disclaimer is on every screen for that reason.

Which standards does it reference?

It names DGUV V17/18, SQP2 and DIN EN 17206 as the real authorities and points you to them. It does not reproduce them, and where a term names a regulation you look up the version in force where you are.

Is it free?

Yes, entirely, with a free Squaresmile account. It needs a tablet or laptop.

Why does it show kilograms instead of kilonewtons?

Because the trade talks in kilograms. Strictly, kg is mass and "force in kg" means kilogram-force; engineering documents use kN (1 kN ≈ 102 kg) or daN. Switch the Unit selector to kN or lb any time; the ⓘ button and the glossary explain the difference.

At 30°, what does each bridle leg carry?

The whole load. T = W ÷ (2 sin α): 0.50 W at 90°, 0.71 W at 45°, 1.00 W at 30° and already 1.93 W at 15°. That is why common practice never goes below 30° from horizontal. See Bridles.

What is uplift?

A support reaction that goes negative — the structure wants to lift off that support. A chain hoist cannot push, so uplift means a slack chain and an unstable truss. The sandbox shows it the moment a load travels past the last hoist.

Does it handle three-point rigs or grids?

No. The model is two supports or two hoists, and two-leg bridles. Three or more hoists on one truss are statically indeterminate — load-cell territory — and outside what the tool teaches.

Are the hardware presets real product data?

No. They are illustrative values that teach the MBS → safety factor → WLL relationship. Use the manufacturer's data sheet for anything real.

Can I share a scenario?

Yes. Copy link encodes the whole scenario in the URL. A colleague opens your exact rig, even if they need to sign in first. See Training and safety factors.

Does my progress sync?

Yes. Saved scenarios, quiz level, streaks and settings sync with your account across devices. See Account sync.

Which languages does it speak?

All eleven platform languages, including the glossary, concept cards and quiz explanations. Formula symbols (R_A, W, α) stay as notation.
