Break Seized Chain Pins Fast — No Torches. No Hammering.
Seized chain pins during a mining emergency repair stop your conveyor and production instantly.
Why Pins Seize in Mining
Mining chains pack with abrasive fines, heat, and corrosion until pins freeze solid. Downtime spikes instantly when a pin won’t move under load. Hydraulic force is the only reliable way to break a seized joint fast and safely.
Why This Failure Happens
WH132, WDH480, and ER864 pins seize when fines, moisture, and corrosion infiltrate bushings and gall the pin surface. Thermal cycling and shock loads wedge debris tight, locking the joint immobile. Once frozen, the chain section binds, drags, and forces an immediate shutdown.
