Break Seized Chain Pins Fast — No Torches. No Hammering.
One concise sentence that restates the problem in the buyer’s environment.
Why Pins Seize in Power Plants
Heat, dust, corrosion, and thermal cycling pack the chain tight and lock the pin.
A seized pin under load stalls the conveyor, kills throughput, and creates immediate risk. Heat, dust, corrosion, and thermal cycling force contaminants into the joint, causing the jammed pin and sudden breakdown that halts the plant.
Why This Failure Happens
WH132, WDH159, H-series, and similar engineered-class chains trap ash, fines, and scale inside the bushing, creating abrasive pack-out that locks the pin. Thermal cycling expands and contracts components, driving corrosion and galling into the joint. Load shocks drive the pin deeper into the press-fit, making it impossible to move without hydraulic force.
Why Operators Choose Kingpin Breaker
Faster downtime reduction with hydraulic force
Safer no-torch extraction on jammed pins
Accurate pin alignment prevents side-loading damage
Portable tool reaches congested conveyor areas
Works reliably across WH132, WDH159, H-series
