Break Seized Chain Pins Fast — No Torches. No Hammering.
Frac sand drag conveyor pins seized from abrasion halt production instantly.
Why Pins Seize in Frac Sand
Heavy sand load, constant abrasion, and packed fines bind chain pins solid. Heat, dust, and thermal cycling accelerate seizure, forcing shutdowns and unsafe torch attempts. Hydraulic removal is the only fast, controlled way to clear a seized pin and restart flow.
Why This Failure Happens
WH132, WDH110, and WDH480 chain pins pack tight with abrasive silica, creating galling and metal-to-metal friction. Heat and thermal cycling deform bores while dust infiltration locks pins under load. Once seized, the pin will not press out without controlled hydraulic force.
Why Operators Choose Kingpin Breaker
Faster changeouts with no-torch hydraulic removal
Safer crews through controlled pin pressing
Accurate alignment prevents chain side-bar damage
Portable tool deploys fast in any drag bay
