Break Seized Chain Pins Fast — No Torches. No Hammering.
Emergency pin seizures in paper mill conveyor chains stop production instantly.
Why Pins Seize in Paper Mills
Heat, steam, dust, and corrosion pack into chain joints until pins seize solid. Drag loads and thermal cycling lock {{failure_mode}} in place and stall flow. Downtime escalates fast, and crews need a no-torch fix now.
Why This Failure Happens
WH132, WDH159, ER864, and similar chains trap slurry, fines, and corrosive condensate that oxidizes pins and bores. Thermal cycling expands and contracts the joints until galling welds the pin to the barrel. Load shocks from thick mats of fiber force pack-out, freezing the pin and locking the entire conveyor.
Why Operators Choose Kingpin Breaker
Faster hydraulic force clears seized pins immediately
Zero-torch removal improves crew safety
Precision alignment protects chain bores from damage
Field-portable tool restores production quickly
