Cranes and rigging fail in one direction: the load comes down. Hooks open up under sustained overload, wire rope breaks wires internally where nobody can see, and slings get cut on sharp edges during a single lift. There is no partial failure and no warning stage that operators reliably notice, which is why the inspection is specified against measurable limits — throat opening, broken wires per lay — rather than against judgement.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Damaged gear stays in the rack because it still lifts. Slings with cuts, hooks missing safety latches, chains with stretched links — all of it works until the day it does not, and it fails under load with people underneath. This is the least ambiguous fatality risk in a fabrication shop.
Monthly for the documented inspection, with a pre-use check by the operator before every lift. Frequency scales with duty class and severity of service, and any gear involved in a shock load or overload comes out of service immediately for examination rather than waiting for the next cycle.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
