Break Seized Chain Pins Fast — No Torches. No Hammering.
Mining crews lose hours when chain pins jam solid from abrasive fines.
Why Pins Lock in Mining
Abrasive fines, heat, and corrosion pack tight around the pin bores fast. Once pinned, the chain freezes and production stalls immediately. You need a hydraulic way to break the seizure before the downtime gets worse.
Why This Failure Happens
Abrasive fines infiltrate WH132, WDH159, and ER864 joints and compact under load, forcing metal-to-metal galling. Thermal cycling and corrosion lock the pin inside the bushing until it cannot rotate or press out. The chain binds, stalls the conveyor, and stops production instantly.
