Break Seized Chain Pins Fast — No Torches. No Hammering.
Sudden chain seizure shuts down your sand plant and stalls production instantly.
Why Pins Seize in Sand Plants
Abrasive dust packs tight around bushings and freezes the pin. Heat, corrosion, and heavy load shocks lock everything solid. Downtime escalates fast when a seized pin won’t move.
Why This Failure Happens
WH132, WDH159, and ER864 chains grind under constant abrasion, forcing dust and fines into the pin-bushing interface. Heat, corrosion, and thermal cycling weld the pin in place, preventing any lateral movement. Load spikes from surges compact the pack-out until the chain link can’t be separated without hydraulic force.
