Electric chain hoists are typically made from a variety of materials designed to resist corrosion. Common materials include:
1. **Stainless Steel**: Offers excellent corrosion resistance and is often used for components exposed to harsh environments.
2. **Galvanized Steel**: Steel that has been coated with zinc to prevent rusting. It's commonly used for the chain and other structural components.
3. **Aluminum**: Lightweight and resistant to corrosion, electric hoist machine aluminum is often used in the housing and frame of the hoist.
4. **Coated or Painted Steel**: Steel components may be coated with special paints or finishes that provide a protective barrier against moisture and chemicals.
5. **Plastic and Composite Materials**: Used for non-load-bearing parts, these materials are inherently resistant to corrosion and lightweight.
These materials help ensure durability and longevity, especially in environments where moisture or chemicals are present.
