Special Cylinders for Marine Equipment
In all kinds of marine application projects, such as transportation, mining, and exploration, a hydraulic cylinder is an indispensable key component. It must be able to resist corrosion and bear huge force. Our technology and R & D center serve the complex and diversified development and innovation of hydraulic cylinders. The targeted application solution can meet the needs of all kinds of operations and maintain long-term and stable operation and safety.
“3S” Hydraulic Cylinders
  • The hydraulic cylinder is the actuator of the hydraulic transmission system, which needs high strength, long stroke, and a thin wall. The way is to stretch and thin the steel pipe with cold drawing technology. Hengcai hydraulic breakthrough cold drawing technology, for the hydraulic cylinders requires super diameter, super stroke, and super-thin wall(3S), we are providing a good solution.
  • "3S" hydraulic cylinders are manufactured by precision cold drawing technology. By using the principle of equal diameter cold drawing, the stress problem of cold drawing steel pipe is well solved. The material completely replaces the "tempering + cutting "process, and the utilization ratio is over 90%. While solving the “3S” problem, the material cost is greatly reduced and guarantees the benefit of both parties.
  • Lightweight Solution of Hydraulic Cylinders
    Lightweight technology is the industrial trend in the future. The application of lightweight technology for parts and components is very important to the performance of energy saving of main equipment. It can be said that whoever grasps the lightweight technology will win the future. Hengcai Hydraulic has been engaged in lightweight research for many years, and forming a mature lightweight core technology, which is applied to hydraulic cylinders of cranes, firefighting trucks, pump trucks, etc. Under the premise of ensuring good mechanical and technological properties, the weight of the whole cylinder is about 20% less than that of conventional products.
  • Built-in Hydro-pneumatic Spring
    Hydro-pneumatic spring is a common buffer vibration absorber, which is composed of energy storage assembly and hydraulic cylinder assembly. The existing energy-storage assembly of hydro-pneumatic springs is an external type. However, the volume of the hydraulic cylinder assembly is usually fixed, so its overall volume is large and can’t be widely used.

    In view of the current situation mentioned above, our technical team has solved the problem and invented a built-in hydro-pneumatic spring that can build the energy storage assembly into the cylinder assembly to greatly reduce the overall volume and thus expand the scope of application. It is also easy to install and remove.
