DIVER   ASSEMBLY

​  Operators have a number of options with regard to the

size and power of the driver and components of the

assembly that can be used to operate the binder.

   A power driver with between 120 to 250   ft. lbs. of

torque can tension the binder to a tension equivalent

to or greater than that which most ratchet binders are

manually tension in day to day operations. 

    A 1/4 inch drivers can do the job, are usually lighter

and less costly, however, require a longer operating period

to achieve an adequate tension, the connection to the

HEX extension bar is not as robust as the square on the

3/8 wrenches and the battery charge is used more quickly.  

      A 3/8 in. impact wrenches appear to be the ideal

     driver for tensioning speed, battery life, weight and

     the operators physical requirements.

This size and weight of a 1/4 and a 3/8 wrench is usually

close to the same weight the, the square 3/8 wrench

 connection to the extension is stronger than that of the

1/4 inch drivers and tensioning is faster.   

   A 1/2 inch or higher capacity impact wrench could be used but is NOT recommended since there significantly heavier, could easily exceed the WLL  of the chain, the

drive assembly parts or the.binder.​​​​

​​​​​     The optimal drive assembly consists of a - an 3/8 impact extension ( length to that chosen by the operator)

  - a 3/8 ball impact universal joint and

  - a 3/8 drive 15/16 in (24 mm)  medium depth impact socket.

     This is the lightest combination and although a standard depth socket can be used

and is easier to engage with the bolt, the medium depth socket provides a more positive engagement with the bolt and helps to minimizes any possible rounding of the bolt head.

        There are several alternate combinations of parts that can make up a  drive 

        assembly.  

         A  standard  15/16 or  24mm - 1/2  in. drive socket can be used with a  1/2 inch ball

        impact universal joint, a  1/2 to 3/8 adapter and a 3/8 extension, however,  this is a

        heavier assembly, and  the  standard socket is less robust and may not stand up

       to the  repeated impacts..

     The extension bar length chosen by the operator  would be based on the  safest

       and most comfortable positioning of the operator relative to the binder.

       The extensions used can be  as short  3 inches or as long as combinations  of a couple

        joined together to reach binders installed in confined  spaces.

              

      NOTE 

​​         A ratchet wrench handle can be used to operate

          the binder when an impact wrench is not available,

          workable or the battery is drained.

          A speed wrench is a good backup tool for quick

          manual closing or opening the binder..

          It is recommended that a spare  backup universal

         joint and socket be  available  in case of a part failure

         or is lost.
