Function：
On the American 7260 crawler crane, the track roller (also called bottom roller) is a critical undercarriage component. Its primary function is to support the overall weight of the crane and transfer this load evenly to the crawler tracks and the ground. This ensures stable operation during both traveling and lifting.
Track rollers are installed along the crawler frame to distribute the load uniformly across the entire track system. This reduces concentrated stress on individual track links and helps extend the service life of both the tracks and the undercarriage components.
Another important function of the track roller is to guide and stabilize the track chain. By keeping the track properly aligned with the crawler frame, the rollers help prevent track deviation or derailment and ensure smooth, reliable movement.
Track rollers also reduce friction and wear by allowing the track links to roll smoothly instead of sliding. This minimizes wear between the track chain and the crawler frame, improving efficiency and durability.
In addition, track rollers help absorb impact and vibration when the crane travels over uneven or rough ground. This protects the crawler frame and upper structure while improving overall operating stability.
