When the line goes down, you need answers — not theory.

Start with the symptom
Why your conveyor belt keeps tracking off — and the order to fix it in
Chasing tracking with the snub roller is treating the symptom. Here's the diagnostic sequence that finds the real cause — bad splices and out-of-square frames included.
Read the guide →Belt slipping on the drive pulley
Squealing on startup under load? Tension is the last thing you should touch. Work the drive side first.
Photo eye keeps faulting? It's rarely the sensor
Before you swap another eye, check what the fault pattern is telling you — running vs. stopped changes everything.
Inspecting sortation shoes before they fail
Shoes announce failure before they let go — if you know where to look. A floor-tested inspection walk-through.
Planning a shutdown without blowing the production window
The maintenance window always shrinks. How to sequence work so the line still starts on time.
Bearing failure: reading the symptoms before it seizes
Grinding at a reducer, a floor that vibrates underfoot — catch it as you walk past, then swap the combo.
Motor overload trips that keep coming back
Two resets, then stop. And "overload" means the circuit opened — not that the motor was overloaded.
VFD faults: read the code, not the panic
OC, OV, OH, GF — four families, four paths. Most "bad drives" are innocent; the code proves it.
The Difference
By the book vs. on the floor
Every guide here includes both: what the textbook says, and what actually happens when the line is down and the operations team is standing behind you.
Written from the management seat at a large automated sortation facility — the judgment calls, the fault patterns, the fix order that manuals don't teach.
