Hydraulic breakers, also known as "hydraulic hammer", "hammers", "peckers", "hoe rams" or "hoe rammers."

Hydraulic breakers have become an important tool for hydraulic excavators. Some people have installed hydraulic breakers on backhoe loaders (also known as two-headed) or wheel loaders for crushing operations.

The power source of the hydraulic breaker is the pressure oil provided by the excavator or the pumping station of the loader. It can more effectively clean the mud in the floating stones and rock gaps in the function of excavating the foundation of the building.
