Break Seized Chain Pins Fast — No Torches. No Hammering.
Seized chain pins in port terminal conveyors can halt ship unloading and choke material flow instantly.
Why Pins Seize in Port Terminals
Heat, dust, corrosion, and abrasion pack into the chain joint until the pin seizes solid. Downtime escalates fast as bulk vessels wait and conveyors stall. Hydraulic removal is the only safe, fast way to break the freeze and get the line moving.
Why This Failure Happens
Seized pins occur when WH132, WDH159, and ER864 joints load, heat, and grind under dust, salt air, corrosion, and thermal cycling. Contaminants infiltrate the bushing, gall the pin surface, and lock the joint immobile under tension. Once frozen, the chain binds, drags, and stalls critical port terminal conveying systems.
