Break Seized Chain Pins Fast — No Torches. No Hammering.
Emergency chain pin seizure is shutting down your coal plant conveyor line now.
Why Pins Seize in Coal Plants
Coal plants run in heavy heat, dust, and corrosion that pack out chain joints fast. Thermal cycling and abrasive fines lock pins until they freeze solid. Downtime escalates instantly when an emergency chain pin seizure stops the line.
Why This Failure Happens
WH132, WDH110, WDH120, and ER864 chain joints load with dust, fines, and corrosion that force metal-on-metal galling. Heat and thermal cycling swell bushings and trap contamination until the pin binds. Load shocks from misalignment or sudden starts then jam the pin so hard it cannot press out in the field.

Why Operators Choose Kingpin Breaker
Faster hydraulic force eliminates seized pins fast
No-torch removal dramatically increases repair safety
Precision alignment prevents chain sideplate distortion
Field-portable system cuts conveyor downtime dramatically
Works reliably on WH132, WDH110, WDH120, ER864
