Dynamic Load

Also: kinetic load

Dynamic load is the peak force applied to a rigging point during motion — a lift, a release, a sudden stop — and can substantially exceed the static load. Rigging engineers calculate dynamic loads with safety factors (typically 7:1 over peak dynamic) to ensure structural integrity. The dynamic load math is why a motor with a static rating of 1,000 lbs isn't lifting 1,000 lbs of gear — it's lifting some fraction with the dynamic factor preserved.
