Break Seized Chain Pins Fast — No Torches. No Hammering.
Stuck chain pins on grain drag conveyors stop material flow and force an immediate shutdown.
Why Pins Seize in Grain Drags
Grain drag conveyors run nonstop until a chain pin locks solid.
Dust, fines, corrosion, and load shock freeze pins in place fast.
Torch removal risks damage, injury, and longer downtime.
Why This Failure Happens
Grain drag conveyors using WH124, WH132, WDH159, and similar chains trap fines and moisture at the pin joint. Abrasive dust packs the clearance, corrosion forms, and thermal cycling locks the pin under load. When a pin seizes, the chain cannot articulate and the conveyor stalls.
