Biurrarena, S.Coop. - Hydraulic hammers

The hydraulics hammers DMB S2200V of Hyundai-Demo have a design in continuous evolution thanks to the studies of investigation and development and to the big investment, elements that guarantee an extraordinary quality, as well as a high up to date technology.%Wing forces of break advanced, the stability and the high speed of percussion, and a remarkable durability have been tested in the most demanding conditions, such as demoliciones of structures of concrete, excavations of tunnels, works in rivers, subterranean structures, etc.?po Of hydraulics hammer have of elder forces of break thanks to the technology tested that combines the hydraulics power and the gas nitrogen. His maintenance is profitable thanks to the simplification of the structure and to the reduction of the number of pieces of spare designed for a greater durability. The shock-absorbers special incorporated in the hammer type carcasa enclosed guarantee a silent operation, and the reduced repercussion diminishes the fatigue of the operarios. The greater number of hits by minute guarantees a greater productivity.?Or model DMB S2200V is of big power thanks to the pistón entered in the hydraulics hammer. It carries incorporated an accumulator that absorbs the pulsaciones and avoids the cavitación. Besides, it has of an arandela of nylon NC, with revestimiento of rubber of butadieno-acrilonitrilo (NBR) and helicoidal nut to facilitate the setting/desmontaje and obtain a greater durability.%Wing application of this hydraulics hammer is thought for minería, break of singings filmed, construction of roads and forestry ways, break of compact rock, and construction of preys and excavation in mulches of rock.?to To his technical specifications stands out his weight in operation of 1.800 kg. His total length is of 2.770 mm. The diameter of the pike is of 135x1.200 mm. The pressesure of work exerted is of between 150 and 170 kg/cm2. The discharge of oil is of between 130 and 170 lpm. The quantity of hits by minute is of between 330 to 530 bpm. The excavadora compatible has to have a weight of between 18 to 25 tonnes.
