All personnel engaged in the excavator industry are familiar with crushing hammers, not only because the wages of crushing operations are higher, but also because the risk and difficulty coefficient of crushing operations are higher than those of ordinary operations.

For the driver, the three points of selecting, striking and maintaining the hammer are the basic skills. However, in actual operation, the breaking hammer often breaks and takes a long time to repair. In fact, one move can solve the problem, that is, to do the following!

Use and maintenance of crushing hammer

First point: check

The inspection of the breaking hammer is basic, and Z cannot be taken lightly. In the final analysis, the failure of many breaking hammers is due to the lack of sufficient attention in case of slight abnormality.

For example, whether the high and low pressure oil pipes of the crushing hammer have been loosened and whether some pipes have started to leak oil, these details must be checked in place to prevent the oil pipes from falling off due to the high-frequency vibration of the crushing operation.

Second point: prevent empty hitting

During the operation of the crusher hammer, many machine operators will think that the problem of empty hammering of the crusher hammer is not serious. This wrong understanding also leads to the wrong operation of everyone. The drill rod does not always keep perpendicular to the broken object, does not press the object tightly, and does not stop the operation immediately after breaking. The situation of empty hammering occurs from time to time.

It seems that the problem of empty striking is not serious, and it does not cause much damage to the hammer itself. In fact, this wrong operation will cause the main bolt to loosen, the front body to be damaged, and even the machine to be damaged! We must take a warning.

Third point: drill rod shaking

No matter how long an old driver has been in the industry, he can not carry out crushing without shaking a bit of drill rod, but such behavior must be reduced to Z low! Otherwise, the damage of bolts and drill rods will be accumulated over time!

In addition, bad habits such as falling too fast and hitting broken objects with heavy blows must be corrected in time!

Fourth point: operation in water and sediment

In places such as water or sediment, the probability of using a breaking hammer is small, but it is not ruled out that the construction may be carried out under this condition. At this time, we must pay attention to that except for the drill rod, the rest of the hammer body cannot be immersed in water or sediment.

The reason is very simple. The breaking hammer itself is composed of precision parts. The precision parts Z are afraid of water and soil, which will seriously affect the performance of the piston, and seriously cause the breaking hammer to break prematurely.

Point 5: continuous operation

Sometimes, when the project time is particularly urgent, the driver will continue to work continuously. At this time, special attention should be paid. When working continuously on hard objects, the continuous breaking time at the same position should not exceed one minute, mainly to prevent high oil temperature and drill rod damage.

Point 6: crushing hammer pushes heavy objects

It is believed that everyone has done more or less the operation of pushing heavy objects with the protective plate of the crusher. In fact, this kind of behavior is very dangerous. On the one hand, it will damage the crusher itself; on the other hand, if the crusher is small, it will cause dangerous accidents such as broken arm and overturning.

Summary:

In fact, although the crushing operation will have a certain impact on the life of the excavator and the crusher hammer, it is not difficult to see from the above introduction that the life of the crusher hammer depends on whether the daily use and maintenance work are done properly!

It can be said that if the broken hammer of the same brand is properly maintained and used, the probability of failure is far lower than that of not being properly used. Therefore, attention to detail not only saves work but also saves money for the wallet!
