I do not see this picture as much as I smell it. Refer trucks all stink like hell.
The size of the shipments are similar to some I make on a regular basis.When I am done they clock in @ about 1200 lbs each.
I know not what those pallets in the pic weigh, I do know they used a metric shit ton of the strapping tape (fiberglass.) Looks like 3/4 inch variety. Triple wrap. The pallets I make use just the outer stretch wrap and they are fine.
The fiber tape, and the white tray on the bottom tell me they did not want this to move at all. I'd prob get fired I use that much shit. There may be an absorbing layer in the bottom tray also, not sure. Would explain why the bottom row of boxes seem a bit taller, to me anyway.
