Towing chain Grade 30

carbon steelcorrosion-resistantwelded

Product overview
Grade 30 proof coil long link chain supplied on a half drum. Electronically welded proof coil construction suitable for general utility applications such as agricultural, logging, towing and switch chains. Finish supplied as self color; hot-dip galvanized finish is available for enhanced corrosion protection.

Key features

• Electronically welded proof coil chain
• Finish: self color (standard) or hot-dip galvanized for corrosion resistance
• Meets or exceeds NACM and ASTM standards
• Intended for general utility use (farm, log, tow, switch)
• Not for overhead lifting; adhere to published WLL

Introduction
Grade 30 proof coil chain is manufactured from low carbon steel and designed as a general-purpose utility chain. Its long link geometry and proof coil specification provide consistent dimensional control and predictable performance for non-lifting applications.

Caution

• Do not use for overhead lifting.
• Do not exceed the published Working Load Limit (WLL).

Parameters

• Grade of Chain: NACM & ASTM classification (Grade 30). Higher grade indicates higher WLL for the same nominal size.
• Working Load Limit (WLL): Maximum recommended working load in direct tension for an undamaged straight length of chain.
• Proof Test: Manufacturing test force applied in direct tension to verify integrity; not to be used as a design service value.
• Minimum Breaking Force: Manufacturer acceptance test value determined under increasing direct tension; not a service design criterion.
• Overhead Lifting: Any lifting operation that would place a freely suspended load where a fall could cause injury or damage.
