Break Seized Chain Pins Fast — No Torches. No Hammering.
One seized pin shuts down a port conveyor and turns a routine shift into an emergency repair.
Why Pins Seize in Port Terminals
Salt air, abrasive dust, and corrosion lock pins solid. Marine exposure, heat, and vibration compound the bind and stall the entire conveyor.
The breakdown is immediate: production stops, crews wait, and materials back up across the terminal. Corrosion, abrasion, and thermal cycling freeze the pin and block the chain. You need it out now.
Why This Failure Happens
WH132, WDH159, ER864, and similar engineered-class chains ingest salt, sand, and particulate, grinding into bushings and galling the pin. Corrosion swells the joint, and thermal cycling hammers the fit tighter until the pin won’t move. Load shocks from ship loaders and reclaim conveyors wedge the link solid and halt material flow.
