RiggingSense
An interactive rigging-statics trainer — drag loads across trusses and bridle apexes, watch reactions and leg tensions solve step by step, and quiz yourself.
On this page
RiggingSense teaches the statics every stage rigger is expected to already know. Drag a load along a two-hoist truss and watch the reactions split — and go unstable when it passes the last hoist. Drag a bridle apex and watch leg tension climb as the legs flatten. Every result can show its full working, and the trainer scores your estimate before it shows the answer.
Who it is for
- Stagehands and apprentice riggers building intuition before the responsibility.
- Lighting and audio techs who hang things and want to understand what the rigger is telling them.
- Students, trainers and toolbox talks — a visual teaching aid with the maths shown.
What makes it different
- Drag it and see. Reactions, bending moment, bridle tensions — all update live as you move the load or the apex.
- Failure modes, named. Uplift when a load passes the last hoist, skew when one hoist takes far more than the other, each explained in plain words.
- Estimate first, then check. A trainer with levels, tightening tolerances, streaks and badges.
- A 20-term glossary linked inline throughout, also published at /riggingsense/glossary.

- FAQ and Troubleshooting.
RiggingSense is free with a Squaresmile account. The sandbox and the bridle views need a tablet or a computer; the training quiz also works on a phone.
RiggingSense is a trainer. Its numbers are for learning — not a load rating, a rig check or a sign-off. It does not replace a competent rigger, the manufacturer's load data or a structural calculation, and it applies no rules for you. In Germany those include DGUV Vorschrift 17/18, DGUV Information 215-313, IGVW SQ P2 and DIN EN 17206; elsewhere, the rules where you work apply.
