Break Seized Chain Pins Fast — No Torches. No Hammering.
Coal conveyor seized chain pins stop production fast.
Why Pins Seize in Coal Handling
WH132, WDH159, and ER864 pins seize when coal dust packs into bushings, moisture drives corrosion, and thermal cycling galls mating surfaces. High tensile loads deform sidebars and lock pins tight. Once seized, the joint stops flexing and the entire conveyor section binds.
Why This Failure Happens
WH132, WDH159, and ER864 pins seize when coal dust packs into bushings, moisture drives corrosion, and thermal cycling galls mating surfaces. High tensile loads deform sidebars and lock pins tight. Once seized, the joint stops flexing and the entire conveyor section binds.
