Break Seized Chain Pins Fast — No Torches. No Hammering.
Stuck chain pins have your bulk handling conveyor locked down and costing you production.
Why Pins Seize in Bulk Handling
Heat, dust, corrosion, and abrasion pack the joints until the pin won’t move. Load shocks and thermal cycling weld the pin into place. Downtime escalates fast when a seized pin stops the entire conveyor.
Why This Failure Happens
WH132, WDH159, ER864, and similar engineered-class chains trap fines, moisture, and corrosion inside the bushing-to-pin interface. Abrasion, thermal cycling, and high-load impacts gall the pin surface and mechanically lock it in place. When the joint packs out, the pin freezes solid and the conveyor stops immediately.
