Break Seized Chain Pins Fast — No Torches. No Hammering.
Emergency Chain Failure Halts Your Asphalt Plant Immediately
Why Pins Fail in Asphalt Plants
Heat, dust, abrasion, and thermal cycling drive mix and fines into the joint until the pin locks solid. Downtime escalates fast when contaminants cook in place. A seized pin shuts down production and forces an emergency repair.
Why This Failure Happens
WH132, WDH159, and ER864 chains trap hot mix, fines, and abrasive dust inside tight clearances. Thermal cycling bakes this contamination into a rigid mass that bonds the pin to the bushing and sidebar. Load shocks deform the pin shoulder, locking it immovable and stalling the asphalt plant’s drag or conveyor system.
