The excavator travel gear is the key mechanism that enables the machine to move efficiently. It includes the track frame, track chains, drive system, and roller assemblies. Powered by hydraulic motors, the undercarriage allows the excavator to move forward, backward, and turn with precision. Built for durability, it withstands heavy impacts and abrasive conditions common in construction sites. Proper maintenance—such as adjusting track tension, lubricating rollers, and clearing debris—is essential to prolong service life and prevent breakdowns, ensuring optimal performance.
