Break Seized Chain Pins Fast — No Torches. No Hammering.
Jammed Conveyor Chain Stops Your Asphalt Line Immediately
Why Pins Jam in Asphalt Conveyors
Heat, dust, fines, and thermal cycling force mix into the joint until the pin locks solid. Production loss escalates fast when contamination packs around the bushing. A jammed pin halts the conveyor and stalls the entire plant.
Why This Failure Happens
WH132, WDH159, and ER864 conveyor chains trap hot mix, dust, and abrasive fines inside the bushing. Thermal cycling cooks the contamination into a hard composite that bonds the pin to the sidebar. Load shocks deform the pin shoulder, locking it immovable and stopping conveyor flow instantly.
