Break Seized Chain Pins Fast — No Torches. No Hammering.
Seized chain pins in grain elevator drives stop production fast and force immediate shutdown.
Why Pins Seize in Grain Elevators
Heat, dust, and corrosion pack into the links until the pin locks solid. Load shocks and thermal cycling drive the seizure deeper. Downtime spikes fast when a frozen pin won’t press out in the boot or head section.
Why This Failure Happens
Grain elevator chains like WH132, WH157, and ER864 trap dust, fines, and moisture inside the bushing until corrosion locks the pin in place. Thermal cycling and heavy start-up loads gall the pin and deform the link shoulders. Once seized, the pin will not budge under hammering and stalls the entire leg or drag conveyor.
