Product OverviewElectronically welded Grade 30 proof coil chain manufactured from low carbon steel. Electro-galvanized finish with optional hot-dip galvanizing for enhanced corrosion protection. Conforms to or exceeds NACM and ASTM standards. Not intended for overhead lifting; always observe the published Working Load Limit (WLL).
IntroductionGrade 30 proof coil chain is a general-purpose utility chain suitable for farm use, log dragging, towing and switching applications. Its long-link geometry offers flexibility and ease of handling while providing consistent performance for non-lift duties.
Caution- Do not use for overhead lifting.
- Do not exceed the published Working Load Limit (WLL).
Parameters- Grade of Chain: Classified per NACM (National Association of Chain Manufacturers) and ASTM; higher grades correspond to higher WLL for the same chain size.
- Working Load Limit (WLL): The maximum working load to be applied in direct tension to an undamaged, straight length of chain.
- Proof Test: The minimum tensile force applied during manufacture under increasing direct tension to verify integrity; this is a production test and not a design criterion.
- Minimum Breaking Force: The minimum tensile force at which chain samples broke during manufacture testing; breaking force values are manufacturing acceptance tests and not guarantees for service design.
- Overhead Lifting: Any lifting operation that could place a suspended load over personnel or property; this chain is not certified for such use.
