Union Bucket Elevator Down: Seized Chain Pin Won’t Press Out
Seized chain pin has stopped your Union bucket elevator and blocked restart.
Why Chain Pins Seize
Your elevator is down and production pressure is building fast.
Torch cutting risks damage and creates serious safety hazards.
Corrosion, wear, and contamination have locked the pin solid—it won’t move.
Why This Happens
Corrosion builds between pin and sidebar, locking components under load cycling. Wear and contamination pack the joint, increasing friction until the pin freezes. Thermal effects and material expansion tighten the fit, turning routine maintenance into a full shutdown.
