Excavator off-chain, commonly known as off-chain, means that the track is separated from the track formed by the driving wheels, supporting wheels, guiding wheels, and supporting wheels. Because excavators often work in harsh environments, and the crawlers are parts that directly contact the ground, when the working ground is bad and the operation is improper, it often leads to disconnection. Below we will list a few common reasons and analyze how to avoid the chain. ---Quanzhou guide wheel

   

Reasons for the excavator to drop the chain

   There are many reasons for track derailment. First of all, external reasons. Too rugged and uneven roads will cause a serious imbalance in the force of the track shoe and cause the track to break away. Secondly, the driver's improper operation and the rough forward and turning operations may also cause the track to derail. In addition to the above two external reasons, the failure of the excavator chassis itself is also a cause that cannot be ignored. Common failures of the chassis are:

   1. Since the radial planes of the several sets of wheels that make up the track of the track are not on the same plane, that is, the track is not aligned, and cannot fit well with the track, resulting in poor rotation of the track and eventually causing the track to leave the track. ---Quanzhou guide wheel

   2. The track is too loose. This is well understood. The loose track will have a relatively large amount of openness during turning operations or uneven ground. The track can not play a good guiding role, and the track derailment is inevitable. .

   3. Due to excessive wear of the chain guard, the chain guard cannot limit the crawler track well, and the track shoe swings too much, causing the chain to fall off. ---Quanzhou guide wheel

   How to avoid losing the chain

   Now that we understand the reasons for track deviance, then we can prescribe the right medicine to avoid the occurrence of off-chain in time, so how to avoid it?

   1. When operating or turning on a construction site with poor ground, if you find signs of preliminary derailment of the crawler, you should stop in time and lift the crawler to idle a few times to return the crawler to the correct position. ---Quanzhou guide wheel

   2. The rotating shafts of the driving wheels, supporting wheels, guide wheels, and carrier wheels should be greased frequently and fully lubricated to avoid excessive wear.

   3. The guide wheel can be moved forwards and backwards to adjust the tightness of the track. Therefore, the guide wheel should be specially protected in normal times. Check whether the tensioning cylinder is working properly and whether the oil seal is leaking. If damaged, it should be repaired or replaced in time.

   4. Check whether the chain guard is excessively worn or loose, and repair or replace if any. ---Quanzhou guide wheel

   5. In addition, always check whether foreign objects such as stones, soil, etc. are involved in the crawler, and if any, clean up in time.
