Ratchet Load Binder

Common Sizes & Ratings

Load binders are sized based on the diameter of the chain they are designed to tension. Most binders are dual-rated for two chain sizes, such as a smaller Grade 70 (G70) chain and a slightly larger Grade 43 (G43) chain.

Usage Guide

• Initial Setup: Extend the screw threads by turning the handle in the “out” or neutral position. Ensure you leave enough thread for tightening.
• Attachment: Lay your transport chain over the load and secure both ends to rated anchor points. Attach the binder’s hooks to the chain links, pulling out as much slack by hand as possible.
• Tensioning: Flip the pawl to the “in” position and pump the handle back and forth. The ratcheting action will pull the hooks toward the centre, tightening the chain.
• Locking: Once taut, ensure the pawl is fully engaged and the handle is in a position that won’t catch on anything. It is common practice to wrap excess chain around the handle to prevent it from vibrating loose.

How to Choose

• Match Working Load Limits (WLL): The WLL of the binder must be equal to or greater than the WLL of the chain. For example, if using 3/8″ G70 chain (rated 6,600 lbs), you must use a binder rated for at least 6,600 lbs.
• Determine Quantity: Federal regulations often require at least four tie-downs for vehicles over 10,000 lbs (one at each corner).
• Environmental Factors: If operating in coastal or winter road conditions, choose binders with powder-coated or galvanized finishes to resist corrosion.

Safety & Precautions

• No “Cheater Bars”: Never use a pipe or handle extension to gain more leverage. This can overstress the binder and cause sudden, catastrophic failure.
• Safe Positioning: Always stand to the side of the handle, never in the “line of fire” if the binder or chain should slip or break.
• Regular Maintenance: Clean and lubricate the screw threads and pawl mechanism periodically with a silicone-based or graphite lubricant to prevent seizing.
• Inspection Checklist: Before every use, inspect for:
• • Cracks, bends, or nicks in the handle or hooks.
  • Worn gear teeth or stiff ratcheting movement.
  • Legible WLL markings; if they are worn away, the binder should be retired.
