Product Description

This component is an extension spring, a precision helical spring fitted with hook‑shaped ends on both sides. Fabricated from high‑strength galvanized steel, it features tightly wound coils to provide stable initial tension.
Installed within poultry breeding equipment, it generates restoring force when stretched, enabling automatic reset and reliable tension control for movable parts of feeding & drinking systems or cage assemblies. It delivers consistent elastic performance, outstanding corrosion resistance and extended service life under long‑term cyclic operation, ensuring stable running of the whole livestock equipment.
