Chain Binder or Load Binder

 

Chain Binder or Load Binder

These two terms are used interchangeably. A chain tensioning device used to bind, clamp, anchor or tie down large cargo loads for transport is what a binder is. chain binders are a device to tighten chain when securing a load for transport. There are two general styles of chain binders –  ratchet binder and lever binder. The method of tightening the binder is what differentiates the two.

 

Ratchet Binder and  Lever Binder

 

Ratchet Binder

Also called a ratchet chain or ratchet load binder, this device uses a ratcheting action to tension chain and secure cargo. A ratchet binder consists of a ratchet handle and two tension hooks on each end.

  • Uses a ratcheting action to create tension in the chain.
  • Because ratchet binders are designed with a gear, handle, pawl, and end fittings, it will not store as much energy in the handle like a lever binder will.
  • A ratchet-type binder is easier to adjust in finer increments without the recoil or snap back effect of a lever binder.

 
Lever Binder

Also called a snap binder, lever chain or lever load binder. Chain-tensioning device uses a leverage action to tighten and secure loads. With a tension hook on each end, this binder requires more strength to tighten than ratchet binders.

  • Uses a leverage action to create tension in the chain and stores kinetic energy in its handle.
  • This type of chain binder generally requires more strength to tighten it.
  • Lever binders are generally easier to install because it has fewer moving parts.

 

Both lever binders and ratchet binders work similarly, and should be chosen based on operator preference.

 

 

How To Choose a Lever Binder/Ratchet Binder?

 

When ordering lever binders or ratchet binders you will find that each size is determined with two measurements. There are two main grades of chain for tie-down applications, Grade 43 high test chain is used for stationary, non-transport tie downs and Grade 70 transport chain is for objects being transported on a flatbed or other moving vehicle. Each binder can be used with either size of equipment chain for the appropriate application, but since the different grades have different load limits each binder will be marked with the appropriate chain dimensions for both types of chain for proper performance. The first measurement (smaller) identifies the Grade 70 chain dimension, the second measurement (larger) identifies the Grade 43 chain size required.

Example: 5/16″ – 3/8″ Lever Binders; the 5/16″ specifies the chain binder can be used with 5/16″ Grade 70 Transport Chain or it can be used with 3/8″ Grade 43 High Test Chain (logging chain.) Small load binders can technically be used for both 5/16″ or 3/8″ chain in either grade, but if you pair this lever binder with 3/8″ Grade 70 transport chain the binder will be weaker than the chain, making the binder the weakest part of the assembly. If you are working with 3/8″ Grade 70 chain, the best option would be to pair it with a 3/8″ – 1/2″ Chain Binder so that the chain and binder are of equal strength. When choosing what grades of chain will go with what binders, be sure to consider both specifications.

 
What are the different sizes for chain binders and how do I choose?

Two measurements determine the size of a lever binder or ratchet binder, but let’s first outline chain grade.

There are two main grades of chain for tie-down applications:

Grade 43 high test chain is used for stationary, non-transport tie downs.

Grade 70 transport chain is for objects being transported on a flatbed or other moving vehicle.

Each binder can be used with either size of equipment chain for the appropriate application, but since the different grades have different load limits each binder will be marked with the appropriate chain dimensions for both types of chain for proper performance. The first measurement (smaller) identifies the Grade 70 chain dimension, the second measurement (larger) identifies the Grade 43 chain size required.

Keep the weakest link theory in mind to maximize your working load limit: choose a work load limit equal to or greater than the chain.
