Track Adjuster

Excavator tensioner assembly 1 Excavator tensioner assembly 2 The track adjuster assembly provides proper tension to the track. A slack track will lead to vibration jump when it moves and excessive slack will also cause track slippage. However, the track cant be adjusted too tightly, otherwise the friction between the track pin and pin bush or the idler would be increased, which will accelerate their wear. The spring of the track adjuster acts as a buffer when the idler encounters an obstacle.

Carrier Roller

Excavator carrier roller assembly The carrier roller supports the upper track between the idler and the sprocket to prevent the track from sagging, which can reduce the vibration jump of the track.
