Excavator [out of the chain] 6 major reasons, how to avoid?

There are many reasons for the dechaining of the excavator. In addition to the impurities such as crawling into the soil or stones, the excavator may be unchained, and the failure of the traveling ring gear, the carrier roller, the chain protector, etc. may cause the excavator to be unchained. In addition, improper operation can cause the excavator to be unchained.

1. De-chaining caused by the failure of the tightening cylinder.

At this point, you should check if the tightening cylinder has forgotten to beat the butter and see if there is any oil leakage in the tightening cylinder.

2. De-chaining caused by severe wear of the track.

If used for a long time, the track must be worn, and the wear of the chain, chain and other components on the track will also cause the track to be unchained.

3. De-chaining caused by wear of the chain protector.

Almost all excavator crawlers have chain protectors, and the chain protector plays a very important role in preventing the chain breakage, so it is also important to check the chain protector for wear.

4. De-chaining caused by wear of the driving motor .

For the drive motor ring gear, if the wear is serious, we need to replace it, which is also an important reason for the excavator to be unchained.

5. De-chaining caused by damage to the sprocket wheel.

Under normal circumstances, the oil leakage of the sprocket wheel seal will cause the sprocket wheel to wear seriously, which will cause the track to be unchained.

6. De-chaining caused by damage to the front idler.

When viewing the guide wheel, check that the screws on the guide wheel are not missing and that there is no break. The slot of the card guide wheel has no variant.

How to avoid derailing the track chain of the excavator

1. When walking on the construction site, please place the final drive motor as far as possible behind the walking to reduce the extrusion of the carrier roller.

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

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

4. Confirm the tightness of the track, adjust the track tightly in soft places such as dirt, and adjust the track to loose when walking on the stone. If the track is too loose or too tight, too loose will cause the track to be easily derailed. Too tight will cause the chain to wear too fast.

5, often check the crawler for any foreign objects such as stones, and if necessary, clean up.

6. Working on a muddy site, you need to idling the soil in the track.

7. Try to avoid the excavator turning in place.

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

Excavator track chain derailed, how to install

Archimedes once said, "Give me a fulcrum, I can pick up the whole earth." When the excavator's track is derailed, how to get it back to normal, you need a fulcrum. Our fulcrum is the excavator's bucket. According to the different conditions of the track derailment, the track can be put back with the tacit cooperation of the bucket and the walking.

The excavator is derailed, but it is a very serious matter. If you are not careful, it is easy to cause an accident. I hope that the majority of friends will pay more attention to their daily work.
