When working on large jobs where the object is to raise the grade by several feet, the common practice with a dump truck and trailer was to raise both boxes about 6 inches above the top of the second stage, just enough to make some of the material slough back against the tailgate, communicate with the spotter, drive by him at about 10 mph and 3 feet away, watch is hand signal and pop the trailer tailgate, count to two, pop the truck tailgate then work the levers for the boxes raising them to the top and dropping them when empty. The result was a nice continuous 8-10" spread of both boxes. We did it this way for years, it was fast and safe. The next truck would come along about 45 seconds behind and spread beside the previous truck.
We started doing this at one local refinery and were told that is was forbidden as unsafe. (We had done this at two previous refineries) Their solution was for us to stop raise our trailer box, and try to get a loaded truck moving again on fairly soft ground without getting stuck. If we succeeded we then had to back our trailers onto the spread we just laid down as straight as possible, meanwhile the next truck was coming by three feet away laying down his trailer. It scared the crap out me at times because it was next to impossible to keep completely in my lane while backing because the trailer wanted to take the path of least resistance. The spotter was required to be well away from the trucks and had to describe where he wanted the gravel on field of gravel. After the job was finished I met one of the general contractor's supervisors at a different job and he mentioned some of the rules they came up with for his operators. In talking about the refinery job, we concluded that it was so safe that is was dangerous.
It's not always the government regulators, sometimes it's somebody who is unfamiliar with how it is done safely.
As a post script, even though this was at a refinery, it was on an undeveloped part of the property with no tanks, oil lines, steam lines or electrical within 300 yards of the job.
