8 models for excavators with operating weight from 0,5 to 11 ton
More power, less vibration and maintenance The SB breakers work with inertial nitrogen energy recovery, thus obtaining more power (more than 30%) and less vibration thanks to the nitrogen chamber that reduces maintenance costs, since it has no diaphragm.
Long lasting of the nitrogen charge In the past, energy recovery breakers required frequent nitrogen refills; with the new sealing system and the new compound developed by Freudenberg they are able to guarantee a gas tightness equal to 300% more than in the past.
Protected tubes The tubes are completely protected through the casing and they’re suitable for every type of excavation, especially in narrow spaces.
Silenced body The particular design, with a closed box casing as well as the insertion of sound-absorbing material, allowed to reach very low noise levels for a breaker.
Double retainer pin The tool locking system with double retainer pin allows an adequate and uniform wear of the same and ensures longer maintenance intervals for the whole locking system.
Monoblock body without tie rods The entire SB series benefits from the particular monoblock construction; this feature gives the structure a very high resistance to leverage, during work. The breaker is built in one only piece and it is without tie rods, thus obtaining greater production and less maintenance as a result.
Only two moving parts.
For all types of installations (pressurization) The SB series tolerates high back pressure and it has a wide calibration range of the required oil flow, in order to get the installation easier.
The piston moves in a single interchangeable cylinder liner that keeps the main body intact and that is easy to replace in case of necessity
The piston is built with a special geometry such as to keep a constant energy of impact, as well as for reducing breakages in conditions of criticality
Visibility and versatility The models of the SB series, with their tapered shape, provide the operator with an excellent view during the work and allow to operate close to the walls, both in narrow section and with open front.
