The principle of selecting a hydraulic breaking hammer is to select the most suitable hydraulic breaking hammer according to the model of the excavator and the working environment. The hydraulic breaking hammer has become an important working tool of the hydraulic excavator. Some people also install the hydraulic breaking hammer on the excavator loader (also known as the two busy) or the wheel loader to perform breaking work. The hydraulic breaking hammer is also called a hydraulic breaker or a hydraulic stone breaker.

[0003] For example, the upper cylinder assembly of the breaking hammer disclosed in (Patent No. CN219157805U) comprises a breaking hammer lower cylinder II, a breaking hammer middle cylinder II and a breaking hammer upper cylinder II arranged in sequence.
