Lever Load Binder

Common Sizes and Ratings

Lever binders are typically sized based on the diameter of the chain they are designed to tension. Most binders can accommodate two different sizes of chain.

How to Choose the Right Binder

1. Match Chain Size: Ensure the binder is rated for the exact diameter and grade (e.g., Grade 70) of your chain.
2. Verify WLL: The binder’s Working Load Limit (WLL) must match or exceed the chain’s rating and be sufficient for the cargo weight.
3. Regulatory Compliance: Ensure the binder meets DOT and FMCSA standards, which require the combined WLL of all tie-downs to equal at least 50% of the cargo’s total weight.
4. Application Speed: Choose lever binders when speed and simplicity are prioritized over the incremental precision offered by ratchet binders.

Usage Steps

1. Inspect: Check for cracks, bends, or worn hooks before every use.
2. Position: Place the chain over the cargo and attach to rated anchor points at a 30-45 degree angle for optimal restraint.
3. Attach Hooks: Connect the binder hooks to the chain links, taking up as much slack as possible by hand.
4. Tension: Pull the handle downward until it is fully locked against the chain.
5. Secure: Use the loose end of the chain or a safety wire to wrap the handle, preventing it from popping open during transit.

Critical Precautions

• No Cheater Bars: Never use a pipe or “cheater bar” to increase leverage. This can overload the binder or cause the handle to snap back violently.
• Handle Path: Always stand to the side of the handle’s path during tightening and release to avoid “kickback” injuries.
• One-Person Operation: Only one person should operate the lever at a time to maintain control and prevent excessive force.
• Stable Footing: Operate from the ground whenever possible; never stand on the load while tensioning.
• PPE: Always wear heavy-duty gloves and safety glasses to protect against sharp edges and sudden tension release.
