    The 2x8s are used to back your trailer tires on. If you can't sit on level ground, you can back the lower tire onto one to help level it up.

    I am thinking about getting into the end dump game pulling a 39ft frameless end dump trailer and what I, do not understand is do you set the brakes on the tractor and not the trailer cause I have seen some guys will stand out side there truck when they lift there dump box and also I thought some of these dump trailers had a manual release on the gate instead of a air release.

    On a frameless trailer you normally hold the tractor and allow the trailer to move forward to allow the load to flow out of the trailer as its raised. I have seen guys stand next to the truck while they dump too. Personally I think it's a foolish thing to do because it can be an excellent way to get killed if things go wrong and the tractor turns over on the driver side. The tailgates can be set up lots of different ways. Some are plumbed into the cab, others may have a switch at the rear of the trailer. I have seen some old trailers still on the road that have a handle to unlatch the gate manually.

    I ran a tractor trailer roll off it had a 80yd box and the trailer itself was about 40feet but the box had some overhang. My controls were on the trailer and you had no option of dumping inside the cab, you had to roll your boxes on and off beside the trailer and it had a brake release on it so you could hold that in and release your trailer brakes to move around as you pull a box on, dump, or roll one off.

    With Frame-Less end-dumps there's a couple of ways to dump.
    1. You can hold the trailer brakes, using the valve or the johnny bar. When the bucket is lifting, the tractor will slowly walk backwards. This is the most preferred method.

    2. You can set the tractor brake, and let the trailer walk forward. However when doing this, you will string or spread the material. I know aggregate businesses, really don't like having it strung out. They prefer a single pile, anyway the ones that I dump at do. Next and most important, it is more dangerous. The material is still in the front of the bed, and while the trailer tires are rolling forward, one could roll over a hump, causing the bed to become uneven, rock and sway. If the bed is up very far, this could easily cause the bed to lay over.

    Now, today I had to pick up another driver to get him back to the shop. His truck broke down, and was on my way back. He's a seasoned veteran driver, probably over 20 yrs experience, and has numerous years running an end-dump. We started talking about dumping, and I learned that he has laid a frame-less over. He admitted it was his fault for not getting out and looking. However the place he was dumping was very tight, he had to jack-knife into it, and they had all kinds of junk laying around. What he did not see was a rollover curb, that was hidden by some tall weeds. His trailer tires were not affected. When his tractor was walking back, one tire walked up this curb, subsequently it was enough to cause the trailer to lean. He also had about 5k lbs of material stuck in the nose. So it went over.

    Ok, this is what he told me the best way to dump..
    Set the trailer brake, using the Johnnie Bar. Raise the bed all the way, watch the material. If it gets built up around your tires, stop raising the bed, place the lever in the hold position, release the Johnnie Bar, foot on the brake. Now gently easy forward. A lot of times it will just roll forward from the pressure of the material. I know rock will do this. This is a very short distance, maybe 1 or 2 feet. Now set the trailer brake (johhny or red valve), and continue raising the bucket.

    Once the bucket (bed) is all the way up, ease forward, until you are just in front of the pile, then bring the bed down, keep the trailer brake set, do not set the tractor brake.

    The method I've described before, where you walk the tractor back, until the bed is about 3/4 up, then set the tractor brake, release the trailer brake, continue to raise the bed, which will cause the trailer tires to roll forward, is for more experienced, and should only be done on hard surfaces.

    Other things you need to do are, dump the suspension (air) on the tractor and trailer, and make sure you have un-done the load locks, both of them. By both I mean the air, and turnbuckle.

    There are those that setup switches inside the cab for releasing the gate, dumping the trailer suspension. Those are nice, I have ran a frame-type, like that. I will say that not having them is better. It forces you to get your lazy behind out of the cab so you can double-check things, especially to LOOK TO SEE IF YOU ARE SETTING LEVEL.

    a frameless trailer will make you a nervous wreck untill you get used to it, and there is such a thing as being too careful. we used to have a driver that would raise his trailer part way up while looking out the back window he would think it was unlevel and would let it down and move, he would do this at least 10 times everytime he dumped a load. he eventually turned one over and was really scared to death after that, and looking out the back window is really dangerous if you think about it. one of our older drivers blew the hydraulic hose while dumping and the hose went through the window and tore up his knuckle of the hand that was on the shifter, and filled the cab with 50 gallons of fluid. could of been seriously hurt or worse if he would of been turned around looking out the window, best way to see if your level is watch your front axle in the mirror make sure both tires come off the ground at the same time "with the trailer brake set" raise the bed all the way up then release the trailer brake and pull forward untill the tailgate clears the pile then set your trailer brake and let the bed down. this is definately the safest way but you will get several different opinions on this

    I do occasionally stand on my step while dumping. Notice I said stand on my step. I have hold of the dump lever, and constantly watch the top of the bed AND the trailer tires that are on the ground. This way I can see if the bucket is starting to lean. If that happens I can place it in hold and/or lower it. I have had one time where I could see that one of the tires was not sitting as flat as the other. Very good indicator that the bucket is starting to lean.

    Yes it will and does, make you a nervous wreck. In just 3 mos time I've dumped well over 100 times, and there are still a few times that I get nervous. If you think something is not right, do not hesitate to stop and check, or lower it. I have stopped raising the bed, got out, walked back, looked just to make sure. Another thing that will mess with your mind while raising the bed, are clouds. It's an optical illusion, but when there are a few clouds moving, and you're looking at the top/front of your bed while it's going up, it will appear as if your bed is starting to lean.

    One place where we have been delivering rock, they have sand, and when you have the bucket raised up, the trailer tires will suddenly sink, due to weight (26 tons in my case) being shifted to just those 2 tires. I absolutely hate delivering there. One indicator of a crappy delivery site is how much it pays. In my case I get paid percentage of truck/by the ton. So the higher the pay most of the time will tell you that it is going to be a more difficult dump site.

    Well I'm off this morning to deliver 26 + tons of salt. This is a good place, ground is solid and very level, it's outside, no building to try to back into. :biggrin_255:
    NightWind Thanks this.

    Hey Beau, no im not working at the moment, worked about 4 days early this month since mid-december, and thats about it. (im hurting) I left the produce hauling to start end dump hauling. As you know, this is the bad time for end dump and all construction around here..everything is very slow...only busy people is granite doing 101 at Espinoza rd and Blackie rd over in prunedale, and theyre still doing only a few days a week... Anyhow i got hooked up with a local end dump hauler, hes got about 12-15 trailers...thing is im the very last one on the list, im just waiting for everything to start moving next month, hopefully i can get rolling... if you know anything by all means, let me know, pm me or something..

    I got my license just last year, and i couldnt start as a rookie, nobody wanted to hire me..although i had non-verifiable experience driving with my dad, my age and driving record was what killed me. SO, i went against all odds and bought a truck, got all my permits and licenses to start running under my own authority.. (now i know i dont need mc number to be hey i didnt plan to just stay local at first haha.)
