Anchor chain Grade 70

towingcarbon steelforged

Overview
Grade 70 Binder Chain Assembly is manufactured from heat‑treated high‑carbon steel for cargo restraint and transport securing applications. The assembly features a gold chromate finish for visual grade identification and corrosion protection and is produced to meet NACM Grade 70 transport chain requirements. The product is intended for transport restraint only and is not suitable for overhead lifting. 1 piece per assembly

Key Features

• Heat‑treated high‑carbon steel construction for increased tensile performance versus Grade 30 and Grade 43 chains.
• Gold chromate surface finish for corrosion resistance and visual grade identification.
• Designed to NACM Grade 70 transport chain specifications.
• Supplied as a complete transport restraint system with factory‑assembled end fittings.

Intended Uses

• Flatbed transportation
• Heavy equipment transport
• Construction machinery restraint
• Agricultural equipment hauling
• Industrial cargo securing

Complete Assembly Configuration
The assembly is supplied as a complete transport restraint system including transport chain and factory‑assembled end fittings.

• Grade 70 transport chain
• Clevis grab hooks or slip hooks
• Transport connection components
• Factory‑assembled end fittings

Transport Load Securement Performance
Grade 70 Binder Chain assemblies are engineered to maintain tension and control loads under dynamic highway transport conditions, including:

• Vehicle acceleration
• Braking forces
• Road vibration
• Cornering loads
• Uneven road surfaces

Heat Treatment and Tensile Performance
Controlled heat treatment of high‑carbon steel increases tensile properties compared with proof coil and high‑test chains, delivering higher Working Load Limits, greater minimum breaking forces and improved wear resistance versus Grade 43 chain.

Hook and End Fitting System
Assemblies are typically equipped with forged transport hooks sized to match Grade 70 chain specifications for direct connection to anchor points and restraint systems. Hooks allow rapid attachment, secure chain engagement and easy field adjustment.

Surface Finish and Corrosion Protection
Gold chromate finish provides corrosion protection, outdoor durability and clear visual grade identification—the standard marking for Grade 70 transport chain in North America.

Manufacturing, Testing and Maintenance
Manufactured to NACM Grade 70 transport chain requirements using heat‑treated high‑carbon steel. Each assembly undergoes proof load testing, breaking force testing, hook and weld inspection and dimensional verification. Suitable for cargo control, flatbed transport, machinery securing and heavy haul operations. Not for overhead lifting. Inspect before each use for elongation, hook deformation, corrosion, weld cracks, coating wear and other damage.
