Towing chain Grade 30

hot-dip galvanised steelcarbon steelwelded

Product Overview
Grade 30 proof coil chain in half-drum configuration. Electronically welded proof coil manufactured from low carbon steel. Finish: hot-dipped galvanized for corrosion protection. Meets or exceeds NACM and ASTM classifications. Not for overhead lifting; never exceed the published working load limit.

Introduction
Grade 30 proof coil chain is a general-purpose utility chain suitable for applications such as farm work, log handling, towing and switch chain duties. Its construction and finish provide basic corrosion resistance for outdoor and industrial use.

Caution

• Do not use for overhead lifting.
• Do not exceed the working load limit.

Parameter

• Grade of Chain: NACM (National Association of Chain Manufacturers) & ASTM (American Society for Testing and Materials) classifications; Grade 30 identifies the chain strength level.
• Working Load Limit (WLL): Maximum recommended load in direct tension for undamaged, straight chain.
• Proof Test: Minimum tensile force applied during manufacturing to verify integrity; not a design or service specification.
• Minimum Breaking Force: Force at which the chain failed under test; used for manufacturing verification, not as a service guarantee.
• Overhead Lifting: Lifting that positions a suspended load where dropping it could cause injury or damage — this chain is not certified for such use.
