I'm currently working for a company that hauls petroleum coke out of refineries and takes it to power plants and ports along the river where it's loaded on barges. My company has 42 "coke trucks". They're all day cab Internationals, Kenworths, and Petes pulling 40 foot end dump trailers. They all have electric tarps and are fairly new. My company also has a "dirt crew" which consists of 3 Peterbilt tandems (dump trucks), several track hoes, dozers, graders, back hoes, etc. The dirt crew does work inside the refineries such as rocking the roads, rip rapping the sides of the lagoons, and things like that. I currently work on the dirt crew and drive one of the tandems, but I have a class A license and have been asking to get transferred to the "coke truck crew". They're waiting on someone to quit I think, and as soon as one of the 42 trucks open up, I will be switching over. I was just curious if anyone had any input or thoughts they wanted to share with me before I make the switch. Has anyone hauled coke before?

I used to haul it years ago. The only thing with coke is its usually wet so in the winter it will freeze! The best thing to do is ask some of the other guys what they do. I don't know how far you will be traveling with it but if its just short runs you shouldn't have to worry about it.
When you are dumping your load be careful! Never put yourself in a position that you can't get out of! Always make sure your level until you learn how your outfit is gonna handle everything. Also keep in ming the domino effect! If your trailer goes over and someone is beside you they are gonna go over also. -
Thanks for the reply. The farthest run I will have with it will be 2 hours. At the yard we have a big wash bay next to the shop where we pull the rigs inside and spray the insides of the trailers with malasis type spray that keeps it from sticking to the sides and bottom of the trailer. Do you lock the tractor when dumping and unlock the trailer? Or is it the other way around? Give me some pointers because I have very little end dump experience. Thanks.

Depends on the trailer, is it a frameless?

With dump trailers always make sure you are on level ground. They can flip. When I would dump I would not set my brake and would let the product push the tractor forward as it was dumping.

Just make sure no one is in front of you! If that load comes out of there fast and hard it will give you a good push....lol
I had a load of coal come out the back like a brick more than once. It usually doesn't let loose till your about to the top, when it did I just held on and hoped it didn't stick to the sides of the trailer!! -
We have 4 end dumps and I have seen them tip over 3 times (same one I should say). Like it has been said before make sure you are level. After the first few times you will have a good reference point of what to look at to see if the trailer is level. Dump the air in both the tractor and trailer before dumping. If it is a scissor frame have the brakes applied on the trailer and let the truck get sucked to it.

I was a trainer with the a local dump company for two years we dumped on pits and on the ground so I think I can contribute a few thoughts.
1. In the winter watch how the sun hits that trailer. If the sun is beating on one side and the other is in shade that is a recipe for a tipped trailer.
2. Lock the trailer and let the trailer pull the tractor backwards. If you dump on the ground and let the trailer come forward it's easier to tip and harder to get the load out. An empty trailer is less likely to go over than a loaded one. You still have to pull forward with the trailer in the air but the load isn't in the nose anymore.
3. Watch that the ground is level not only where you dump but all along the path you will have to pull forward.
4. Don't forget to set the trailer brakes and release the tractor when you lower your trailer otherwise you will push the trailer back onto the load you just dumped- a good way to tip your trailer.
5. Keep your trailer clean- loads stick less in a clean trailer no matter what the load is.
I worked for Curry Ice & Coal in central Illinois and during the winter it was not unusual to hear of at least one trailer a day tipping. I always watched the hydralic pin and the bucket through the back window.multiplebogey Thanks this. -
I really appreciate all the replies. I'm soaking up all of this advice guys. Sometimes I will be dropping off a load of coke at the port and then stopping by the rock quarry for a load of crusher run to brimg back. Mostly 1" 1/2 and 3". Sometimes a load of sand or 3/4" class A rock. These loads are usually picked up and dropped off at various construction sites on the way back. So....they won't be dumped on concrete like they will be at the port. When dumping gravel, crusher run, or sand on a job site do I raise the trailer up half way with the tractor unlocked until it slides out, then pull forward a little bit so my mud flaps don't get burried under the pile and ripped off? After pulling forward (or letting the trailer come forward while raising up) do I raise it on up to it's highest point? Then, while it's all the way up...do I creep forward until the tailgate is away from the pile before letting it come down?
