Hydraulic Pump: Pressurizes hydraulic fluid to power the excavator’s movements.
Hydraulic Tank: Stores hydraulic fluid.
Swing Bearing: Allows the upperstructure to rotate on the undercarriage.
Boom: The main arm of the excavator, providing reach and elevation.
Arm (or Stick): Connects to the boom and holds the attachment.
Bucket Cylinder: Controls the movement of the arm.
Boom Cylinder: Controls the movement of the boom.

  1. Undercarriage:

Tracks (or Wheels): Provide mobility and stability.
Track Frame: Supports the weight of the excavator.
Idlers: Guide and tension the tracks.
Sprockets: Drive the tracks.
