Product details
Excavators are complex machines with many components, and the undercarriage is crucial for their mobility and stability. Here are the main undercarriage parts you might find on an excavator: Track Chains: The continuous chain that wraps around the sprockets and provides traction. It’s made up of numerous links and is critical for moving the excavator. Track Rollers: These rollers support the weight of the excavator and help the track chain move smoothly over the undercarriage. They include both carrier rollers and bottom rollers. Sprockets: The toothed wheels that drive the track chains. They engage with the track links to propel the excavator. Idlers: These are the wheels located at the front of the track system that help guide the track chain and maintain proper tension. Track Adjuster: This component is used to adjust the tension of the track chain to ensure proper operation and to prevent premature wear. Track Shoes: The metal plates attached to the track chains that provide traction and support the excavator's weight. Suspension System: Includes the components that absorb shocks and help smooth out the ride. It can be made up of springs, hydraulic cylinders, or other systems depending on the excavator model. Track Frame: The structural framework that supports the track rollers, sprockets, and other components of the undercarriage. Carrier Rollers: Positioned above the track, these help guide the track and reduce wear on the upper surface. Bottom Rollers: Positioned underneath the track, these support the track’s weight and help it move smoothly. Regular maintenance and inspection of these parts are essential for ensuring the longevity and proper function of an excavator's undercarriage.
