Excavator track chain is a key undercarriage part that bears the machine weight and provides driving force. According to material, it can be divided into steel track chains and rubber track chains.

Steel track chains are made of high-strength alloy steel with forging and heat treatment. They feature high wear resistance, strong load capacity and long service life, widely used in mining, quarry, construction and harsh working conditions.

Rubber track chains are light, quiet and shock-absorbing. They protect roads and reduce vibration, suitable for small excavators, urban construction, landscaping and indoor working environments.
