    depends what your doing, Ive been working at a school recently and any time you get out even to pop the tail gate you are required to have both, we were doing ~12 loads in 8 hours with a framed 28' trailer

    I've found that it's the construction sites that are the most strict on this. Lyons Salt Mine in Lyons, KS has this requirement, but they have relaxed this. I've not seen any drivers wearing hard hats or vests while outside their trucks. My first time loading there, I put my hardhat on, then seen no one else was wearing one, so haven't since.

    As i was reading this thread,there's one tip nobody has mentioned.

    Overhere (Europe) the trailerbuilders put small spiritlevels (the one's like they use in the building trade,just the glass withe the airbubble)on the dumps.

    If you put one on your dashboard and one on the trailer,it will take the guessing out off if you are level or not.
    Very cheap to do and will help a lot.

    Re-reading this thread as I'm going out on one of our dump trailers tomorrow. Since my dump experience is limited to running a tri-axles, I'm going out with another driver for a bit of "training" on working with end dumps.

    At our company though, the owner has stated that he prefers to initially dump a frameless with the trailer brakes set, pulling the tractor back toward the trailer. His theory is that by doing this you lessen the risk of laying the unit over as the trailer is stationary and not moving over any potentially uneven ground as the body is going up. Watching a few videos on YouTube, it seems that most (at least the ones that were filmed) dump this way, pulling forward carefully towards the end of the maneuver.

    That is the recommended way but the tractor must be in a straight line with the trailer or you could bend / break a draft arm and over it goes

    Gotta rig it so you can pop the gate from the cab.

    The context that I gave that answer was the guy had never dumped one of these trailers, and I felt that was the least complicated way to do it for a first time operator. No matter what method you choose the trailer has to be pulled forward to empty the load out, so if the ground is that uneven another location should be chosen to dump. For myself I use a combination of the two methods as demonstrated in this video. He holds the trailer until 1:30 then sets the tractor brakes and pulls the trailer to the tractor.

    Question!
    I occasionally do haul 1 of 2 end dumps..one a regular highside for roofing tear-off, the other an endump fitted with 2 vacuum tanks that "vacuum" up rock off a roof..out of all the times I've dumped I have never released air out of the bags..

    My question is what am I missing out on! Haha Or what is a good reason to do so?

    BTW
    My preferred method is hold the trailer handbrake and let the truck scoot back to the trailer.And don't forget your mud flaps! Some of us aren't lucky enough to have them on the swing door!

    you dump the suspension to take the bounce out of it. with the suspension aired up the dump body is resting on air bags instead of the trailer axles, and this allows it to sway more while in the air. also as the trailer is loaded the leveling valve adds air to the bags as weight is being applied to them. when it comes time to dump, while dumping the weight is shifted off the bags faster than the leveling valve can compensate. the rapid loss of weight on the bags will cause them to extend and can cause the trailer to tip over.
