Learn How It Works

Abrasion, Moisture, and Shock in Engineered-Class Chain

Mining conveyors run continuously under abrasive, contaminated conditions.

Moisture intrusion and corrosion bond pins inside bushings over time.

When a pin seizes, production stops and downtime escalates fast.

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.

Why This Happens

Drag conveyors, bucket elevators, and apron feeders operate in abrasive, dust-heavy environments. Fine material packs into joints while moisture and corrosion bond pins to bushings. Shock loading and misalignment accelerate galling, leading to seized pins and sudden conveyor stoppage.

Why Operators Choose Kingpin Breaker

Removes seized pins without torch cutting

Hydraulic press-out force overcomes corrosion bonding

Precision alignment prevents sidebar damage

Field-portable for tunnels and enclosed conveyors

Works on drag, elevator, and engineered chain
