Break Seized Chain Pins Fast — No Torches. No Hammering.
Coal Conveyor Pins Jammed by Slurry Abrasion During Critical Downtime.
Why Pins Seize in Coal Conveyors
Slurry, fines, and abrasive grit pack tight around the pin and bushing. Heat, dust, and abrasion weld everything together under load. Your chain locks up, production stops, and the failed pin won’t move.
Why This Failure Happens
WH132, WDH159, and ER864 pins trap abrasive slurry between plates and bushings. Pack-out grinds metal surfaces, drives corrosion, and loads the pin until it galls in place. Thermal cycling hardens the jam, locking the chain and stopping the conveyor instantly.
