Normally the excavator is equipped with a hydraulic breaker hammer when it is used for lightweight crushing and demolition operations, such as crushing and repairing concrete pavements and cement pavements. However, how to choose a suitable hydraulic breaker hammer is also a matter. The following is a brief explanation of how to choose a breaker.

• Weight of excavator 
  

excavators should match suitable excavator as a small excavator with a large breaker may cause the excavator to tip over and a large excavator with a small breaker is very inefficient and easily damaged at the same time. So an excavator matching with suitable hydraulic breaker hammer can maximize working efficiency of the excavator.

• Working weight of hydraulic breaker hammer

The flow rate of the breaker determines the working frequency of the breaker, which in turn affects its striking power and working efficiency. When the output flow of the excavator is greater than the required flow of the breaker, the hydraulic system generates too much heat, and the components are easily damaged if the temperature is too high, which will reduce the service life of the excavator. When the output flow of the excavator is less than the required flow of the breaker, there is simply not enough heat. Power driven breaker operation. Therefore, it is necessary to choose an excavator and breaker with a suitable flow rate.
