Calculation support, not a guaranteed safety decision.

A load lifted or held above ground stores gravitational energy that is released if the load falls.

High-energy check

Most suspended loads exceed the 1500 J high-energy trigger. Treat as high energy unless calculation shows otherwise.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

For your SPA or pre-start

State the load mass and lift height, the direct controls that keep people out from under the load, and who verifies them before the lift.
