The undercarriage of an excavator includes several vital parts, such as track chains, rollers, idlers, and sprockets, which support the machine’s weight and enable its movement across different terrains. Regular maintenance and replacement of worn-out spare parts, including filters, hydraulic hoses, pins, bushings, seals, and electrical components, are crucial for the excavator’s longevity and efficiency. High-quality parts from reputable brands like Caterpillar, Komatsu, Hitachi, Bobcat, Volvo, and Doosan are recommended.
