Union Bucket Elevator Down: Seized Pin Won't Press Out
Seized chain pins stop Union bucket elevators cold during critical repairs.
Why Pins Seize in Service
Corrosion and contamination pack around pins; they won't move under normal press force.
Wear from load cycling tightens fits; restart stays blocked until pins come out.
Downtime mounts fast when torches risk further damage on stuck pins.
Why This Happens
Corrosion builds between pin and sidebar from moisture and debris exposure. Contamination packs in, while repeated load cycling wears surfaces and reduces clearance. Result: pins seize solid, blocking disassembly and stalling equipment restart.
