DSB & DFX-Series

With reference to DSB and DFX series, Demarec has chosen to design and build “nitrogen” hamers in order to obtain a high power distributed over a higher number of blows per minute, thus resisting high counterpressures up to 25 bar. The hamer is also very compactly structured to reduce stress on the excavator arm and ensure greater durability of both the hamer itself and its components.
 
• The DSB and DFX hydraulic hammers can work on any type of excavator and on any singleacting hydraulic system; they are also suitable for hydraulic systems with high back pressure
• Demarec hammers are equipped with special polyurethane shock absorbers that absorb vibrations, thus protecting the arm of the excavator and also reduce noise emissions, according to the requirements of directive 2000/14 / EC
 
 
The Demarec hammers of the DSB series are suitable for carriers, mini excavators, miniblades, backhoe loaders, demolition robots. etc...
The Demarec hammers of the DFX series are suitable for medium and large crawler and wheeled excavators, etc...
