The undercarriage of a mini excavator (typically machines under 8 tons) is its foundational moving system, often called the "travel system" or simply "the tracks." It is a complex assembly of components that serves three critical functions:
1.Supports the Machine's Weight: It bears the entire weight of the excavator and its load.
2.Provides Propulsion: It transfers power from the hydraulic motors to the ground, enabling the machine to move, steer, and position itself.
3.Acts as a Stable Base: It provides the stability needed for digging, lifting, and other tasks.
