Break Seized Chain Pins Fast — No Torches. No Hammering.
Port Conveyor Chain Jammed — Production Stops Until the Pin Moves
Why Pins Jam in Port Conveyors
Salt air, corrosion, and packed debris lock pins solid during heavy load cycles.
Port crews lose hours when chain won’t move, seized under heat, dust, and abrasion.
Hydraulic force is the only safe, fast way to break a jammed pin loose now.
Why This Failure Happens
WH132, WDH110, and ER864 pins seize when salt, dust, and moisture infiltrate the bores and pack tight. Corrosion expands against the bushings while thermal cycling and load shocks gall the pin surfaces. The result is a fully jammed port conveyor chain that will not press out by conventional methods.
