Why to buy Hydraulic Breaker Sampierana: More power, less vibration and maintenance. The HBS 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 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. The particular design, with a closed box casing as well as the addition of sound-absorbing material, allowed the breaker to have very low noise levels. Double retainer pin. The tool-locking system with a double retainer pin allows adequate and uniform wear of the same and ensures longer maintenance intervals for the whole locking system. Monobloc body without tie rods. The entire HBS 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 HBS series tolerates high back pressure, and it has a wide calibration range of the required oil flow, in order to make 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 as to keep a constant energy of impact, and to reduce damage in any critical condition. Visibility and versatility. The models of the HBS 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 and wide spaces. Hydraulic system for blank firings. The hydraulic system creates a regenerative oil circuit that preserves the breaker from blank firings when the tool is not in contact with the rock.
