• Specification

• Function 

1.Tension Maintenance: In the track system, the spring ensures consistent tension between track links and segments. As the excavator operates on uneven terrain, the spring absorbs impacts and adjusts for changes in track length due to wear or thermal expansion, preventing excessive slack or over-tightening that could lead to derailment or accelerated wear.

2.Shock Absorption: When the excavator encounters sudden obstacles or rough ground, the spring compresses to cushion the impact, reducing stress on the track frame, sprockets, and other components. This helps maintain smooth operation and extends the lifespan of the track assembly.

3.Vibration Damping: During high-speed travel or heavy-duty digging, the spring’s elasticity dampens high-frequency vibrations, minimizing noise and fatigue on the operator and the machine. This improves operator comfort and reduces the likelihood of component damage from prolonged vibration.
