↔ Drag the loads along the beam to reposition them — the centre of gravity updates live.
Indicative planning aid only — NOT a rigging certification or structural sign-off. Always have loads checked by a qualified rigger.
Planning only, not an engineering check. This totals the weight you are hanging and where its centre of gravity sits. It does NOT tell you whether a truss is safe, that depends on the make, length, support points and dead-hang vs ground-support. Always check the manufacturer's load chart and use a qualified rigger.
