Excavator track parts are components that make up the undercarriage system of an excavator. These parts work together to support the weight of the excavator, provide traction, and enable smooth movement. Here are some essential excavator track parts:
1. Track Chains: Also known as track link assemblies, these are continuous loops of interconnected metal links that form the main structure of the tracks. They support the weight of the excavator and provide a surface for the track shoes to rest on.
2. Track Shoes: These are the components that make direct contact with the ground. They are usually made of durable steel and come in various designs, such as standard, single grouser, double grouser, or triple grouser, depending on the specific application and ground conditions.
3. Track Rollers: Mounted along the bottom side of the track chain, track rollers help guide the tracks and distribute the weight of the excavator. They rotate as the tracks move, reducing friction and allowing smooth operation.
4. Carrier Rollers: Located at the top of the undercarriage, carrier rollers provide additional support and help maintain proper track tension. They ensure the correct alignment of the tracks and help reduce wear on the track links.
5. Idlers: Idlers are stationary components located at the front and rear of the undercarriage. They play a crucial role in maintaining proper tension and guiding the track chain. Idlers also help distribute the weight of the excavator across the undercarriage.
6. Sprockets: Sprockets are the toothed wheels located at the ends of the undercarriage. They engage with the track chain and provide the driving force to move the excavator. The rotation of the sprockets propels the track chain, enabling the excavator to move forward or backward.
7. Track Tensioners: These components are used to adjust and maintain the correct tension in the track chain. Proper tension is essential for optimal performance, longevity, and reduced wear of the undercarriage components.
8. Track Guards: Track guards, also known as track frame guards, are protective plates that cover the sides of the undercarriage. They help prevent damage from debris, rocks, or other objects that may come into contact with the tracks.
9. Track Bolts and Nuts: These are fasteners that secure the track shoes to the track chain. They ensure that the track shoes remain securely attached during operation.
10. Track Bushings: Track bushings are cylindrical components that provide a bearing surface for the track pins. They help reduce friction and wear between the track links and pins.
