Towing chain Grade 100

steelalloylashing

Product Overview
Grade 100 Binder Chain is manufactured from Grade 100 alloy steel and supplied fully assembled with clevis grab hooks on both ends. The design factor is 4:1. These assemblies are intended for lashing/towing applications and are not recommended for overhead lifting in this configuration despite Grade 100 material being approved for lifting in other configurations.

Introduction
Grade 100 chain offers approximately 20% higher working load limit (WLL) versus a comparable Grade 80 chain of the same nominal size. The binder/tow configuration (also referred to as Tow/Binder, Alloy Log Chain, Grade 10, System 10, Spectrum 10) is equipped with clevis grab hooks that do not include a cradle, allowing the hook to pass through flatbed trailer rub rails for secure lashing.

Parameter

• Grade of Chain: NACM & ASTM classifications specify chain grades; higher grade indicates greater WLL for a given chain diameter.
• Working Load Limit (WLL): Maximum recommended working load in direct tension on an undamaged straight length of chain.
• Proof Test: Manufacturing integrity test applying a minimum tensile force under increasing direct tension during production; not a service design criterion.
• Minimum Breaking Force: Manufacturer acceptance test force at which chain specimens break under increasing direct tension; not to be used for service design.
• Overhead Lifting: Defined as any lifting that suspends a load where dropping could cause injury or damage; this binder configuration is NOT recommended for such use.
