Changzhou Huanyu Shock Absorber Co., Ltd.( Original name: Changzhou Huanyu Shock Absorber Factory) is a professional manufactory in line with wire rope shock absorber, rubber shock absorber, and other shock absorbers. We cooperate with famous universities and study with national power experts together, and have applied for national patent for wire rope shock absorbers. 　　　In recent years, we have been successful to support the match equipments for many institutes in china, such as Aerospace box, Beijing institute of missiles, Chinese Academy of Sciences, Police & Fire Research Institute, Shanghai Machinery Group and so on. In 2002, the Second Artillery Force of the PLA—the specific manufacturing institute in Military and Medical areas in china, has received accredits from Beijing University of Aeronautics &Astronautics. With the R&D of new shock absorber in special specifications and requirements, our company can supply design as well as technical consult. 　　 The introduction of wire rope shock absorber 　　 Wire rope shock absorbers are developed as a new type of vibration and erosion components basing on the theory of modern isolation and erosion. The products are widely used in aircraft, tanks, armored vehicles, field communication equipment, surface ships, submarines, satellites, missiles, transport and launch system, spacecraft, nuclear equipment, facilities, nuclear power plants, underground civil air defense projects, anti-earthquake construction facilities, offshore drilling platforms, industrial machinery and other kinds of power. 　　Wire rope shock absorbers have three features, namely variable stiffness, variable damping and environmental adaptability. These characters make it with a better effect in anti-red and vibration isolation. And the damping elements of the shock absorbers are made of stainless steel material, with resistance of high temperature, low temperature, warm, mold, salt spray, radiation, which is the basing of its long service life.
