Hapman Chain-Driven Equipment Down: Seized Pin Won’t Press Out
Seized chain pin has stopped your Hapman conveyor and blocked restart.
Why Chain Pins Seize
Line is down and pressure is on. Torch risks damage and safety issues. Pins won’t move due to corrosion, wear, or contamination buildup.
Why This Happens
Corrosion and contamination pack around the pin, locking it in place. Repeated load cycling wears tolerances and allows material ingress. Once seized, the pin resists pressing and stalls equipment restart.
