Grade 70 Transport Binder Chains and Chain Tensioner

Transport Chains and chain binders are tough truck tie downs, both chains and binders are made of carbon steel, compare to tie down straps, the chains and binders have higher working load limit , if we compare 5/16” grade 70 chain(typical WLL 4700lbs)to 2” tie downs(typical WLL 3333lbs) ,  3/8” chain(WLL 6600lbs) to 4” tie downs(5400lbs) , the grade 70 chains are stronger than ratchet tie down straps and the grade 70 load binders are stronger than grade 70 chains, 3/8”-1/2” chain binder has WLL of 9200lbs, which is much stronger than 6600lbs of 3/8” chains . If we examine the design factor of chains and tie down straps, we will see that chains and binders have 4:1 design factor while tie down straps have design factor 3:1, that’s another reason we consider chains and binders are heavy duty tie downs .

The National Association of Chain Manufacturer recommends that the steel which can be used to make grade 70 binder chains must have less than 0.35% Carbon, 0.040% Phosphorous and 0.050% Sulfur. When chain manufacturers make their chains to the specification of NACM, and these chains meet or exceed DOT(or CHP, or some other local requirements ) requirements, these chains can be used on the commercial truck to haul heavy loads, such as backhoe, forklift .

We use these heavy duty chains and binders to haul heavy equipment, for instance, backhoe, bulldozer, forklift, these big rigs are tough or straps, we have to use steel chains to tie them down , when we talk about backhoe, forklift, we need at least 3/8” grade 70 chains and binders to secure them, for something which has less weight we consider 5/16” chains are good fit, of course we still have 1/2” and up chains and binders, these chains will most likely be used to tie down something out of ordinary, such as battle tanks, or some other applications require super heavy duty chains.

Binder chains can be used for any purpose except overhead lifting. You can use these chains for tearing down trees, tow heavy objects, we some times use these chains to tow our mobile loading dock. We’ve seen forestry service companies use a lot of these chains and binders in their work as well.
