✅ 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.
Luoghi: Track drive, bucket chain, slewing mechanism, auxiliary conveyor. Funzione: Convertire la coppia del motore in un'alimentazione precisa del materiale e in un movimento di lavorazione efficace.
OEM: Caterpillar*, Komatsu*, Volvo CE*, Hitachi*, Liebherr* systems. *Compatibility reference only.
Selezionare: 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.
Installare: LOTO → allentare la catena → rimuovere il vecchio pignone → montare il nuovo (TL = cambio rapido) → allineare → tendere 2-3% → lubrificare → testare.
Problemi: Denti della catena usurati = pignone usurato (sostituire entrambi). Vibrazioni = disallineamento/eccentricità del foro. Rumore eccessivo = catena secca. La catena salta = catena allungata + denti usurati (sostituire entrambi).
Pilbara, WA: “Precision sprockets matched OEM specs. Running well.” ★★★★★
Sydney, Nuovo Galles del Sud: “Split hub saved hours during shutdown. Material certs provided.” ★★★★★
Brisbane, Queensland: “Consistent quality across multiple orders. Hardened teeth lasting well.” ★★★★☆
Adelaide, SA: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Melbourne, VIC: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
