Introduction
Grade 30 proof coil chain is manufactured from low carbon steel and serves as a general utility chain for applications such as farm work, log handling, towing and switch chains.

Caution

• Do not use for overhead lifting.
• Never exceed the working load limit (WLL) published for the selected chain size.

Parameter

• Grade classification: NACM and ASTM grading; higher grade indicates higher WLL for the same chain size.
• Working Load Limit (WLL): Maximum recommended load in direct tension for an undamaged straight length of chain.
• Proof Test: Manufacturer-applied minimum tensile test during production; intended as a manufacturing integrity test, not for service or design calculations.
• Minimum Breaking Force: Test result from manufacturer acceptance testing; not a guarantee for service use or design.
• Overhead lifting definition: Lifting that would place a suspended load where a drop could cause injury or damage; this product is not rated for that use.

Standards
