As a crucial attachment in rescue equipment, the hydraulic breaker is a high-performance tool that converts hydraulic energy into impact work, mainly used to break hard materials such as concrete, rock and masonry quickly in rescue scenarios like building collapse, earthquake and traffic accidents, helping rescuers clear obstacles and save trapped people efficiently. Its core components are made of high-strength alloy steel: the piston is forged from 42CrNiMo alloy steel with excellent high-temperature resistance and corrosion resistance, capable of withstanding 500 °C temperatures from prolonged friction; the chisel (a key working part) adopts super wear-resistant TSG46A/TSG48A alloy steel or high-hardness 42Cr steel, which is wear-resistant and impact-tough, and its service life is 50% to 100% longer than that of ordinary 42CrMoA materials; the housing is made of Q335Mn or Q345B steel plate, processed by sandblasting derusting and electrostatic spraying, with IP65 protection level to resist dust and rain erosion. This hydraulic breaker features compact structure, light weight and strong compatibility, which can be flexibly mounted on excavators, skid steers and other carrier machines, suitable for narrow rescue spaces. It has adjustable impact frequency (1200-2200 times per minute) and impact force, which can switch between high-frequency low-force and low-frequency high-force modes according to different obstacle materials, ensuring efficient breaking while reducing secondary damage to the surrounding environment. Equipped with a shock-absorbing accumulator and pressure overload protection valve, it can reduce vibration damage to the carrier machine and avoid component damage caused by excessive pressure, ensuring stable operation in harsh rescue environments. In addition, it has the advantages of easy maintenance, low noise (≤110dB) and energy saving.
