Learn How It Works

Why drag conveyor chain pins seize

Dust, fines, and moisture drive rapid pack-out that locks pins solid under load.

Heat, abrasion, and corrosion accelerate seizure until the chain freezes mid-run.

Downtime escalates fast when a seized pin stops the entire drag conveyor.

Downtime escalates fast when a seized pin stops the entire drag conveyor.

Why This Failure Happens

Drag conveyor chains such as WH132, WDH159, and WR78 trap fines, dust, and moisture between the bushings and pins, accelerating corrosion and galling. Load shocks and thermal cycling deform pin interfaces until they no longer rotate or release. Once seized, the pin locks the flight and stalls the conveyor, forcing an immediate shutdown.

Why Operators Choose Kingpin Breaker

No-torch safety for dust-class and hazardous drag environments

Hydraulic force presses out fully seized pins

Precision alignment protects chain bores during removal

Field-portable unit handles WH132/WDH159/WR78 easily

Cuts downtime by removing frozen pins fast

Real Breakdown Scenarios We Fix

WH132 pin frozen solid from fines pack-out during peak shift.

WDH159 pin seized after thermal cycling and moisture intrusion.

WR78 flight jammed when corroded pin refused to rotate under load.

Drag conveyor stalled after shock load mushroomed a pin in the bore.

Chain locked mid-run when a packed, abrasive slurry seized multiple pins.
