Why Does the Crawler of Down-the-hole Drill Rig Jump off the Chain?
In the use of down-the-hole drill rig, the crawler often jumps off the chain. Affected by environmental factors, this situation can not be avoided in the working process. Now let us talk about the reasons for this phenomenon.        

1. The common faults of the tensioning hydraulic cylinder will cause the chain disconnection. At this time, check whether you have forgotten to apply grease to the tensioning hydraulic cylinder and whether there is oil leakage in the tensioning hydraulic cylinder.

2. The crawler of DTH rig machine is damaged seriously, which will cause its jumping off the chain. Once used for a long time, the crawler will be damaged, and the damage of the chain bar, chain barrel and other components on the crawler will also cause the crawler to fall off the chain.
