PPG has been using air bags for years. They put them between totes.
I suppose it should work for LTL. But it takes time. Something we dont have a lot of.

they make a loud bang when you deflate them.

boy you hit that on the nose!! so now i suppose we will have the guys that cant work as fast as the rest run around inflating bags on trailers??? and when he gets hit with a forklift by one of your (trust me im on your team) guys. he will just say i couldnt move fast enough.

We use the bags here at UPS Freight they work great.

FXF also. They do work good, but are time consuming. More crap (air hoses) to have in the isle or door to run over. Plus the PT college dock prefer to deflate them AFTER unloading all the skids. Or just stick a fork in it. They look real neat to someone - especially in the video. But in the real world it's kind of like telling everyone to keep their fork at a brisk walk pace and pedestrians have the right of way on the dock......

Well, we will know in 30 days...
