Chain Binder or Load Binder
Chain Binder or Load Binder
These two terms are used interchangeably. Un dispositivo tensor de cadena utilizado para atar, abrazadera, Anclar o amarrar grandes cargas para su transporte es lo que es una carpeta.. chain binders are a device to tighten chain when securing a load for transport. There are two general styles of chain binders – ratchet binder y lever binder. The method of tightening the binder is what differentiates the two.
Ratchet Binder and Lever Binder
Carpeta de trinquete
También llamada cadena de trinquete o aglutinante de carga de trinquete., Este dispositivo utiliza una acción de trinquete para tensar la cadena y asegurar la carga.. Una carpeta con trinquete consta de un mango de trinquete y dos ganchos tensores en cada extremo..
- 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.
Carpeta de palanca
También llamado carpeta a presión, cadena de palanca o carpeta de carga de palanca. El dispositivo tensor de cadena utiliza una acción de palanca para apretar y asegurar cargas.. Con un gancho de tensión en cada extremo., esta carpeta requiere más fuerza para apretar que las carpetas con trinquete.
- 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, Grado 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″ Grado 70 Transport Chain or it can be used with 3/8″ Grado 43 Alta cadena de prueba (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″ Grado 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″ Grado 70 cadena, 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:
Grado 43 high test chain is used for stationary, non-transport tie downs.
Grado 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.
