FAQs

Grade 70 transport chain is specifically designed for tie-down applications in the trucking industry. It has a working load limit about 25% lower than Grade 80 chain of the same size, but meets DOT requirements for cargo securement. Grade 80 alloy chain is heat-treated for higher strength and is typically used for overhead lifting applications when paired with appropriate fittings.

Key differences:

• Grade 70: Yellow zinc-plated, marked with "7" on each link, ideal for transport securement
• Grade 80: Blue color-coded, marked with "8" on each link, used for lifting when properly configured

Selecting the proper ratchet strap involves considering several factors:

1. Load Weight: Calculate the total weight you need to secure. The combined working load limit (WLL) of all straps should be at least equal to the load weight.
2. Webbing Width: Wider straps (2" or more) distribute force better and are required for heavy loads. Narrower straps (1") are suitable for lighter applications.
3. Break Strength: Ensure the break strength (typically 3-4 times WLL) provides adequate safety margin.
4. End Fittings: Choose appropriate hooks or fittings for your anchor points (flat hooks for D-rings, wire hooks for stake pockets, etc.)
5. Environment: Consider UV resistance, corrosion protection, and temperature requirements.

For overhead lifting, industry standards typically require a minimum 5:1 safety factor (break strength to working load limit). This means:

Working Load Limit (WLL) = Break Strength ÷ 5

Important considerations:

• Always use equipment specifically rated and designed for overhead lifting
• Inspect all components before each use
• Consider dynamic loads and shock loads in your calculations
• Consult a qualified engineer for complex or critical lifts

Our Grade 80 and Grade 100 chains meet ASME B30.9 standards for overhead lifting when used with compatible fittings.

We recommend the following inspection schedule for tie-down straps:

• Before each use: Quick visual inspection for obvious damage
• Monthly: Detailed inspection of all components
• Annually: Comprehensive inspection by qualified personnel
• After any overload event: Immediate inspection before reuse

Inspect for:

• Cuts, fraying, or abrasion on webbing
• Corrosion or deformation of hardware
• Proper operation of ratchet mechanisms
• Legible working load limit markings

When in doubt about a strap's condition, retire it from service. Our product guides include detailed inspection criteria.
