Professional English Translation (Excavator Undercarriage Industry Standard)
I. Core Guiding Function
It guides the track to rotate along the correct path, prevents track deviation and derailment, stabilizes the track travel route and avoids track falling-off failures.
II. Supporting & Pressure Equalizing Function
On most machine models, it also serves as a track roller. It enlarges the track ground contact area, reduces ground specific pressure, and improves the machine’s trafficability and overall stability.
III. Tension Adjusting Function
It cooperates with the tensioner to adjust track tightness, reduces track sagging and bouncing, cuts down wear and extends the service life of tracks.
IV. Shock Absorbing & Buffering Function
It absorbs impact force transmitted from the ground, lessens machine vibration, and enhances smoothness during traveling and operation.
V. Auxiliary Control Function
It ensures smooth track movement, indirectly improves the machine’s steering flexibility, and enables more precise movement and operation in narrow spaces.
