The excavator undercarriage is a critical component responsible for supporting and propelling the entire machine, ensuring stable operation across various terrains. Its primary functions include providing power, supporting the machine’s frame, transmitting driving force, and ensuring mobility and stability in complex environments.

The undercarriage consists of the following key parts:

• Travel Motor (Hydraulic Motor): Supplies driving force by converting hydraulic energy into mechanical energy to rotate the tracks.

• Track (Crawler Belt): Directly contacts the ground, providing traction and stability. Typically made of high-strength steel to adapt to different terrains.

• Sprocket (Drive Wheel): Connects the travel motor to the track, transmitting power to move the track.

• Idler Wheel (Guide Wheel): Guides the track’s movement and maintains proper alignment, usually located at the front.

• Carrier Rollers (Bottom Rollers): Support the machine’s weight and distribute pressure evenly to reduce ground impact.

• Track Rollers (Top Rollers): Support the upper part of the track, preventing sagging and ensuring smooth operation.

• Track Frame (Undercarriage Frame): Supports and secures all components, ensuring structural stability.
