Hydraulic breaker, also known as hydraulic hammer, are powerful tools used in various construction and demolition projects. These robust machines are designed to break through tough materials like concrete, rock, and asphalt with ease.
Hydraulic breakers are commonly utilized in construction, demolition, and mining activities.
They can be affixed to various hydraulic excavators, including mini-excavators, as well as other carriers such as skid steer loaders, backhoe loaders, tractors, boom systems, and other machinery.
Rocka offers a complete range of Hydraulic Hammers designed for excavators. Our hydraulic rock hammers are compatible with all brands and models of excavators.
Rocka Hydraulic Breaker hammer provides optimal power and cost-effectiveness, delivering exceptional performance.
- Demonstrates its true worth in a wide range of applications, from road construction to mining operations.
- The dual-speed impact frequency allows for adjustable hammer speed, maximizing productivity.
- Operates at low pressure, requiring minimal oil.
- Boasts a more robust and long-lasting structure.
- Combines hydraulic pressure and nitrogen gas for increased power.
