Break Seized Chain Pins Fast — No Torches. No Hammering.
Stuck chain pins in aggregate conveyors bring production to a dead stop and require immediate removal.
Why Pins Freeze in Aggregate Plants
Heat, dust, corrosion, and abrasion pack the chain joints until the pin seizes solid. Once frozen, the link won’t move and the conveyor stalls, driving costly downtime. Hydraulic force is the only reliable way to break the bind fast without torch risk.
Why This Failure Happens
WH132, WDH480, ER864, and similar engineered-class chains trap fines, slurry, and moisture under heavy load, forcing contamination into the bushing and galling the pin. Thermal cycling and shock loads deform the joint until the pin locks in place. Once seized, no hammer or puller can move it, and the conveyor stays down.
Why Operators Choose Kingpin Breaker
Faster hydraulic force clears seized pins instantly
Zero-torch removal improves safety and reduces risk
Precise alignment prevents link or sidebar damage
Field-portable setup cuts repair time dramatically
