Nowadays, The use of excavator hammer breakers is more and more widespread. We often see hammers at many job sites, It plays a vital role in urban and rural construction so making a good crushing hammer is our mission.

The power source of hydraulic breaker is an excavator and loader, which can effectively clean up floating stones and soil in the cracks of rocks in the role of excavating the foundation of the building.
Select Hydraulic Breaker/Hammer For Excavator
When choosing a hydraulic breaker, please consider the following aspects:
The weight and bucket capacity of the excavator

The weight of the excavator must be for reference, it can prevent the excavator from falling down because of the heavyweight of the hydraulic breaker when the boom is fully extended.
If the hydraulic breaker model is too large, the excavator might fall down, if the hydraulic breaker is too small, the excavator couldn’t exert the function of the excavator, which also accelerate the damage of the hydraulic breaker. So the excavator and hydraulic breaker could be fully utilized when their weights match.

Light Type Hydraulic Breakers Specification
The working flow and working pressure of the hydraulic breaker
The working flow of hydraulic breakers is different for different hydraulic breakers. The working flow of hydraulic breakers ranges 23L per minute from 400L per minute. When selecting a hydraulic breaker, the working flow of the hydraulic breaker must be consistent with the output flow of the excavator spare valve.
The working flow determines the working frequency of the hydraulic breaker, that is the impacts per minute, the working flow is proportional to the number of impacts. When the output flow of the excavator spare valve is larger than the demand flow of the hydraulic breaker, the hydraulic system will generate too much heat, which will cause the system temperature too high and reduce the service life of the components.
