Break Seized Chain Pins Fast — No Torches. No Hammering.
Chain jammed in your aggregate conveyor and production is dead until the pin moves.
Why Pins Jam in Aggregate Conveyors
Dust, fines, and abrasion pack the chain tight until the pin refuses to move. Heat and thermal cycling lock everything harder. Downtime climbs fast when a jammed pin stops the entire line.
Why This Failure Happens
WH132, WDH159, and ER864 pins bind when fines force their way into bushings and grind surfaces into a mechanical lock. Thermal cycling tightens tolerances while corrosion and abrasion weld the pin to the bushing. Load shocks then deform components enough that the pin cannot move without hydraulic force.

Why Operators Choose Kingpin Breaker
Faster hydraulic force clears jammed pins immediately
Zero-torch removal improves safety under pressure
Precision alignment prevents side-load damage
Portable design fits tight conveyor pits
