LeMar Chain-Driven Line Down: Seized Chain Pin
Seized chain pin halting your LeMar equipment operation.
Why chain pins seize
Production stopped dead by seized chain pins.
Torch attempts risk fire and further damage under pressure.
Corrosion, contamination, and wear lock pins solid.
Why This Happens
Contamination and corrosion build up in pin joints during operation. Wear from load cycling deforms contact surfaces, raising friction. Pack-out and thermal effects seize the assembly, preventing pin removal and stalling repairs.
