How to avoid the derailment of the excavator track chain?

1. When walking on the construction site, please try to place the walking motor behind the walking to reduce the pressure on the supporting sprocket.

2. The continuous walking time of the machine should not exceed 2 hours. The walking time at the construction site should be reduced as much as possible. If necessary, it is recommended to stop shortly before walking.

3. Avoid raised hard objects when walking, so as not to cause stress set on the rail chain.

4. Confirm the tightness of the track, adjust the track tightly in the soft place such as soil, and adjust the track loose when walking on the stone. Tracks that are too loose or too tight are not good. Too loose will cause the track to easily derail, and too tight will cause the chain sleeve to wear too quickly.

5. Always check whether there are foreign bodies such as stones in the track, if necessary, clean them up.


6. When working on a muddy construction site, it is necessary to often idle to drain the mud deposited in the tracks.

7. Try to avoid the excavator turning in circle.

8. Regularly check the rail guard and the welded rail guard under the guide wheel.
