Everyone will encounter a very annoying thing in life, that is, the things you use break down and need to be repaired. Since you can't repair it, you must hire someone to repair it. Not only does it cost a lot, but also waits for after-sales personnel to repair it, which is wasteful Time wasted a lot of things. Especially machinery things, because it involves some knowledge blind spots of everyone, like some cheap machines, it can be said that they can be replaced directly, but some expensive machines are not just replaced, such as the telescopic excavator arm. Large-scale construction machinery and equipment are really maddening when they fail. For workers, it delays the construction period and affects their work types. Moreover, it does not mean that the equipment is replaced. After all, the cost of telescopic excavator arm is also very expensive. Repairs are also time-consuming and costly. But in fact, many users neglect that the machine can reduce the incidence of accidents through maintenance, and even keep your telescopic excavator arm in an efficient working state.

To know how to reduce the occurrence of failures through maintenance, we must first know which telescopic excavator arm failures we will face.

Generally, what we will encounter is abnormal noise of the telescopic excavator arm, and the boom is the key to whether the entire telescopic excavator arm can be used normally. Because it participates in the work of excavators: excavation, loading and unloading, and repair work, so there can be no faults. Generally, when the excavator is under normal construction, if the operator can hear the obvious abnormal noise of the boom pin, it is most likely that it is malfunctioning.

Then how do we carry out inspection work?

1. Check if you use pure butter

2. Whether to beat butter on time

3. Whether the butter nozzle is blocked

4. Whether the shaft sleeve and sealing ring are worn

After completing this series of troubleshooting, it is necessary to carry out troubleshooting. If the inspection is that the grease nipple of the boom pin is intact, the grease on the pin is relatively dry, and the boom pin is not lubricated, causing abnormal noise of the pin during dry grinding. The maintenance master can lift the boom, replace the shaft sleeve, seal ring, pin shaft; assemble the boom, tubing, circuit, boom cylinder and other parts, and re-lubricate the grease, so that the problem is solved.

In fact, the failures mentioned above are caused by improper maintenance. As long as we do a good job of maintenance, we will avoid such failures. So don’t just focus on your own technology and work. The maintenance of the excavator’s telescopic excavator arm is also very important. After all, “work must be sharpened first if you want to benefit your work.” The machine is not flexible, so how can our technology be good? How to work with peace of mind?
