Working Principle
The undercarriage is driven by the hydraulic system, which powers the travel motor to rotate the sprocket, propelling the track. The idler wheel and carrier rollers ensure proper track movement, while track rollers prevent sagging. The track frame maintains overall stability, allowing the excavator to move flexibly across rough terrain.
