Astec Chain Equipment Down – Seized Pin Won’t Come Out
Your Astec chain-driven line is stopped because the pin is frozen solid.
Why Pins Seize and Stick
Seized pins kill production and put crews at risk every minute the line stays down. Corrosion, heavy wear, and contamination lock pins in place so hammers and torches fail. You need a safe, reliable way to break them free fast before the shift is lost.
Why This Happens
Chain pins seize from corrosion buildup, abrasive contamination packing the joint, and repeated load cycling that wears the fit. Once the pin binds, mechanical methods usually fail and heat methods create serious safety hazards. The result is extended downtime and increased injury risk during removal attempts.
