An Extension Spring is a mechanical component that is used to create resistance to a pulling force between two opposing components. This type of spring absorbs and stores mechanical energy. The initial tension determines how tightly together the spring needs to be coiled during the manufacturing process.
Heavy-duty extension springs work by absorbing and storing energy as well as creating a resistance to pulling forces. When the wire is rotated backwards during the coiling process, it creates the initial tension, which can then be manipulated to attain load requirements for any application. The initial tension is what determines how tight the spring is coiled. Pulling the spring apart undoes the rotation and also develops initial tension. The engineering design normally calls for hooks, or eyes, at the ends of the spring which attach to the opposing components. Extension springs with hook ends are often used to provide return energy to components that extend in an activated position.
For over 60 years, WCS Industries has been manufacturing extension springs that are used in a wide variety of industries and applications.
