Parameter

• Grade of Chain: NACM / ASTM classification; Grade 70 for transport and towing applications.
• Working Load Limit (WLL): Maximum recommended working load in direct tension for undamaged chain.
• Proof Test: Minimum tensile force applied during manufacturing to verify integrity; not to be used as a design criterion.
• Minimum Breaking Force: Manufacturer test value showing the force at failure under controlled test; not a service guarantee.
• Overhead Lifting: This chain is intended for pull/towing and load binding; do not use for certified overhead lifting unless explicitly rated and certified for such use.
