Undercarriage
The excavator undercarriage is the bottom section of an excavator that houses various moving parts.

1. Excavator Tracks
The tracks of the excavator, typically made with steel-reinforced rubber, move the machine. Some excavators are wheeled but function similarly to those with tracks.

2. Track Frame
The track frame is where the excavator tracks attach to the undercarriage, functioning similarly to axels.

3. Track Pad
Track pads can help prevent excess noise, vibration and damage, as well as provide better traction during operation.

4. Track Chains
Track chains are what allow an excavator to move efficiently. They function similarly to bicycle chains in that they’re made up of connected flexible links.

5. Track Shoes
If you imagine the tracks of an excavator, the track shoes are the individual parts of the track that dig into the ground and pull the excavator along.

6. Track Bolts
Track bolts link each track shoe together to form the entire track.

7. Rock Guards
Rock guards are exactly what they sound like — they attach to the tracks of your excavator to protect the machine from debris and stray objects.

8. Sprockets
Sprockets are the mechanisms that run between the excavator track chain links. They behave like a giant bicycle sprocket, moving the chain along to propel the machine.

9. Rollers
Rollers are the metal wheels on an excavator undercarriage used to align the chains and move them between the sprocket and idler. There are two sets of rollers — bottom and top — to facilitate chain functionality.

10. Idlers
Bigger than rollers, idlers are large metal wheels within the undercarriage that help guide the excavator tracks. Idlers are the final mechanism that keep tracks running smoothly, along with the rollers and sprockets.
