Break Seized Chain Pins Fast — No Torches. No Hammering.
Jammed chain pins in cement conveyors stop material flow and trigger immediate production losses.
Why Pins Jam in Cement Conveyors
Cement conveyors run hot, dusty, and abrasive, driving corrosion, pack-out, and bushing drag. Thermal cycling and contamination lock pins in place until they won’t move. Every hour down risks lost tonnage and unsafe torch attempts.
Why This Failure Happens
WH132, WDH159, and ER864 chain pins trap dust, fines, and slurry until corrosion and pack-out seize the pin in the bushing. Heat and thermal cycling expand components unevenly and create metal-on-metal galling. Load shocks drive the pin deeper into the sidebars, making removal impossible without hydraulic force.
