Break Seized Chain Pins Fast — No Torches. No Hammering.
Biomass drag conveyor down with seized chain pins causing immediate shutdown.
Why Pins Seize in Biomass Conveyors
Biomass systems run hot, dusty, and abrasive, driving corrosion and galling into every joint. Thermal cycling and pack-out lock WH- and WDH-series pins solid. Downtime escalates fast when seized pins stop the drag line.
Why This Failure Happens
WH132, WH157, and WDH110 pins seize when abrasive biomass fines infiltrate bushings, moisture accelerates corrosion, and heat cycles expand and contract link bores. Galling and pack-out wedge pins immobile under load, forcing full conveyor shutdown.
Why Operators Choose Kingpin Breaker
Faster hydraulic force ends seized-pin delays
Zero-torch method eliminates fire and burn risks
Precise pin alignment prevents side-load failures
Field-portable setup minimizes outage duration
