So I was put OOS today...

And I need some help as to why. I was written for a unsecured load violation. I'm hauling AC units and the total load is 15k lbs. the first stack is two units tall and I strapped it down according to the diagram that the shipper provided. Here's what happend.

I secured the upper unit with a chain that attached to the ac unit and ran it down through the rub rail and back up to the upper unit ( see photo below) I then took a binder and had it secured under the rub rail. I then did the same on the other side of the trailer.

The total weight of the units on that stack was 11850lbs. So with my 2 chains and two binders I was overly secured I thought.

Each binder has a wll of 5400lbs
Each 5/16th grade 70 chain has a wll of 4700lbs.

So add 10800lbs of binders plus 9400lbs of chains equals 20200lbs.

20200lbs of securment minus 11850lbs of freight equals 8350lbs over over securment which should of meant that I was ok to roll...

However he said that because of only having 1 chain and 1 binder on each side of the freight the WLL was cut in half which means that with two chains and 2 binders I was actually 1229lbs short on securment.

The resolution to this problem was two undo the binder and add another one each side ( photo below)

What he listed under "Violations discovered" are as follows.

"Insufficient aggregate working load limit, 50% of 11850, 5/16 grade 70 chain w/5400 binder, short 1229lbs, 1st set of tiers rear of drop deck"

I'm so confused. Anyone know why the WLL was cut in half? I sure don't. All this happend after I told him that I didn't have any receipts to show him... Was this guy just trying to get me for anything he could?

 

The photo above is of the load after I added one more binder per side.
