The sprockets are first molded or forged and subsequently processed, giving them a special heat treatment. If steel does not contain sufficient quantities of carbon, then it becomes brittle during the hardening process. If only the surface is hardened, then the sprocket or segment will wear very fast over time.

The excavator's front idler is engineered with high-quality steel, designed to harden well and provide toughness. It undergoes a specialized molding process to prevent gas formation and receives a specific heat treatment on the surface for enhanced depth hardening, ensuring a longer life.

360 degree rotation makes the machine more flexible,the maximum digging reaches 4.1 meter.

The hydraulic turnout tamping machine is suitable for tamping operations of complex and difficult turnout sections in line maintenance.
