Astec Chain-Driven Equipment Down: Seized Chain Pins
Seized chain pins are blocking restarts on Astec chain-driven equipment.
Why Pins Seize Up
Seized pins stall operations, driving up downtime costs under pressure. Safety hazards spike from risky torch methods during urgent fixes. Corrosion, wear, and contamination jam pins tight, halting movement.
Why This Happens
Corrosion builds up over time, bonding pins to chain links. Wear from load cycling expands metal, creating friction that locks components. Contamination packs in debris, leading to failures that stop equipment cold.
