Advantages vs Inferior / Working Principle
✅ 4140 alloy steel for extreme shock loads — C45 fails in this application.
✅ HRC 45-55 hardened teeth — resists rock/mineral abrasion.
✅ Split hub / QD for field replacement — minimises expensive downtime.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
Locations: Track drive, bucket chain, slewing mechanism, auxiliary conveyor. Function: Convert motor torque into precise material feed and processing motion.
Compatibility / Selection
OEM: Caterpillar*, Komatsu*, Volvo CE*, Hitachi*, Liebherr* systems. *Compatibility reference only.
Select: ❶ Match chain pitch ❷ Shaft bore → hub type ❸ Tooth count for speed ratio ❹ Material grade for environment ❺ Surface treatment for corrosion protection.
Install / Troubleshoot
Install: LOTO → release chain → remove old sprocket → mount new (TL = rapid change) → align → tension 2-3% → lubricate → test.
Issues: Chain riding teeth = worn sprocket (replace both). Vibration = misalignment/bore runout. Excessive noise = dry chain. Chain skipping = elongated chain + worn teeth (replace both).
