Break Seized Chain Pins Fast — No Torches. No Hammering.
A failed chain in your aggregate conveyor stops production until the damaged pin is removed now.
Why Emergency Failures Hit Aggregate Conveyors
Dust, fines, and abrasion load the chain until a pin locks without warning. Corrosion and thermal cycling tighten everything as downtime costs climb fast. Emergency chain repair becomes unavoidable when the system won’t move.
Why This Failure Happens
WH132, WDH159, and ER864 pins bind when fines grind into bushings and create abrasive pack-out. Thermal cycling compresses tolerances while corrosion and galling weld the pin to the bushing. Heavy load shocks then deform components, forcing emergency removal when the chain seizes completely.
