How to avoid derailment of excavator crawler chain

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

2. The continuous walking time of the machine should not exceed 2 hours, and the walking time on the construction site should be minimized. If necessary, it is recommended to walk after a short stop halfway.

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

4. Confirm the tightness of the crawler, and adjust the crawler tightly in soft places such as soil, and adjust the crawler loosely when walking on rocks. Too loose or too tight the track is not good, too loose will cause the track to easily derail, too tight will cause the chain sleeve to wear too fast.

5. Frequently check whether there are foreign objects such as stones involved in the crawler, and clean up if any.

6. Working on a muddy construction site, often idling to drain the soil deposited in the track.

7. Try to avoid turning the excavator on the spot.

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