It is divided into two types: handheld and airborne. The working principle of a hydraulic breaker is to provide power through a hydraulic system to make the piston move at high speed, thereby generating an impact force for breaking hard substances. This device has a wide range of applications in fields such as construction, mining, and road construction. The design of the hydraulic breaker takes into account safety and efficiency, but there are also some precautions during use.
