Break Seized Chain Pins Fast — No Torches. No Hammering.
Seized chain pins from extreme heat have your asphalt drag conveyor dead-stopped and losing tons per hour.
Why Pins Seize in Asphalt Drags
High heat, dust, and abrasion bake fines into the barrels until pins lock solid. Thermal cycling expands the bushings and traps the pin. Every hour of downtime burns production and pushes safety risks higher.
Why This Failure Happens
WH132, WDH480, and SB102 chains run in hot, abrasive troughs where fines, asphalt dust, and corrosion pack into the barrels. Heat expansion and thermal cycling tighten the press fit until galling and metal-on-metal friction seize the pin. Once stuck, the pin won’t rotate, won’t press out, and locks the entire drag section.
