Truck Chains and ratchet binders are tough truck tie downs, both chains and binders are made of carbon steel, the WLL of the chains and binders are higher than most comparable tie down straps , let’s look at 5/16” transport chain(WLL 4700lbs) vs. WLL 3333lbs 2” ratchet tie down straps ,  3/8” chain(WLL 6600lbs) to 4” tie downs(5400lbs) , you will see that compare to tie down straps, binder chains are much stronger, and chain binders are even stronger than same size chains, for instance, 5/16”-3/8” binder has WLL 5400lbs which is stronger than 4700lbs WLL of 5/16” grade 70 chain . 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 .

According to NACM recommendations, the carbon steel used in making grade 70 chains should meet following criteria: no more than 0.35% Carbon, 0.040% Phosphorous and 0.050% Sulfur . As long as the choice made by chain manufacturers meets the recommended criteria and the final products meet or exceeds DOT requirements(or CHP, California Highway Patrol, or some other mandated requirements), we can use these products for transportation purpose and don’t have to worry about inspections.

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.

As we stated above, transport chains, or say binder chains are used on a lot things except for overhead lifting. There are people who use these chains to tear trees, to tow mobile loading docks, a lot of forestry services use large quantity of these grade 70 chains.
