Break Seized Chain Pins Fast — No Torches. No Hammering.
Bucket elevator chains fail when stuck or seized pins stall the leg without warning.
Why bucket elevator pins seize
Fines, moisture, and heat drive rapid pack-out that freezes pins and forces unexpected downtime.
Corrosion and thermal cycling lock elevator pins solid until the boot or head section stops instantly.
Once pins seize up, production halts and maintenance loses hours clearing the jam.
Why This Failure Happens
Bucket elevator chains like WDH110, ER1244, etc. trap fines, dust, and moisture between bushings and pins, accelerating contamination and corrosion.
Thermal cycling and load shocks deform pin interfaces, creating galling and binding that stops rotation entirely.
Misalignment and packed-out debris escalate friction until the pin seizes and the elevator stalls immediately.
Why Operators Choose Kingpin Breaker
No-torch pin removal for hazardous elevator environments
Hydraulic force breaks fully seized pins loose fast
Precision alignment protects elevator chain bores
Field-portable design for rapid boot-pit deployment
Works on common WDH110, WDH120, ER864, and ER1244 elevator chains

How it Works
From Setup to Break in Minutes.
Real Breakdown Scenarios We Fix
WDH110, WDH120, and ER864 elevator chains pin frozen solid from corrosion after weeks of moisture intrusion
Packed fines in boot section causing complete pin seizure and unexpected leg stall
Galling on elevator chain pin locking the bucket strand during high-load discharge
Misaligned sprocket tightening pin interface until the drive section locks abruptly
Thermal cycling in hot/dusty environments causing progressive pin binding and full stoppage
