Break Seized Chain Pins Fast — No Torches. No Hammering.
Scrap yard chain pins seized during an emergency jam, stopping your conveyor instantly.
Why Pins Seize in Scrap Yards
Heat, dust, corrosion, and metal fines pack tight around the pins and lock them solid. Downtime escalates fast when frozen pins block apron feeders or drag chains. A seized joint under load becomes immovable and demands immediate hydraulic removal.
Why This Failure Happens
Scrap yard chains like WH132, WDH159, and ER864 pack with steel fines, dust, and rust until the pin and bushing gall solid. Thermal cycling and shock loading deform the link plates, increasing friction and locking the pin. Once seized, the joint will not articulate, forcing a full shutdown until the pin is hydraulically pushed out.
Why Operators Choose Kingpin Breaker
Faster hydraulic force breaks seized pins instantly
Safer no-torch removal in harsh scrap environments
Precise alignment prevents chain or plate distortion
Portable unit reaches tight conveyor access points
Works reliably on WH, WDH, ER, and WS chains
