    Been driving a bobtail tanker for a year and just scored a local Class A job. Whoo! It's for a very semi large company (50 truck fleet) in Central California. I'll be starting on super dumps and transfer dump trucks before moving into double pneumatic tankers. I've never operated a dump truck other than driving them around at my last company. I know I'll pick it up but I'm looking for advice on transfer dumps. What's it like to back them? Do you spend a lot of time doing reverse maneuvers? My impression is that you drop the transfer in a safe area with space and return for the second load. Obviously the tight tricky backing would be reserved in the bobtail. Am I on the right page? Not concerned about backing the bobtail bc I've put that thing in some scary places this year on fireroads and steep canyons. I'm interested in knowing how a transfer pivots and moves vs a semi trailer.

    Your putting the cart before the horse. No big deal on the stuff your worried about. Easier to back than a semi, not much backing except for transferring the pup back onto its trailer. Fireroad's no big deal, go slow pay attention, check each section of road as good as you can for on coming traffic before committing to it. Again take your time and be very observent. First learn to drive, then worry about the details. Personally I prefer the air cans over the transfer.

    Taking the transfer out tomorrow for the first time. Taught myself how to transfer the boxes in the yard yesterday. All good so far but I attempted to back up the trailer without success. With a semi, I always watched the rear tandems. However, there are two pivot points on this thing! The darn thing kept getting away from me. I tried backing it like a semi but it was nit working out. Should I be watching the rear wheels or the turntable in front of the trailer? I'm assuming this is similar to backing doubles.

    With doubles u actually have 3 trailers to try and back... Think of it more as backing a hay wagon with a truck... Whichever way u want the trailer to go cut the wheel that way. But make sure u do it slowly and not sharp at all or you'll be pulling up before u know it

    So it's opposite of backing a semi?

    Kind of... Whichever way u want the rear end of the trailer to go cut the wheel that way... For example... U need to back the trailer to the right... Cut the steering wheel to the right... But remember avoid cutting it too sharp and don't do anything fast

    You're referring to something like this?
    [​IMG]

    Where you disconnect the trailer, dump out of the power unit first, then back up to the trailer with your high lift raised, roll the hopper from the trailer into the dump body of the power unit, lock it in, then dump it like you would a straight truck?
    I've only had to operate them a couple times. The biggest thing of course being careful to ensure that the hopper is locked in place and secure. Other than that, I'd try to evaluate where I was delivering to, and set myself up so that there was no need to back out if it was possible to do so. But the best way to learn how to back them is to practice. Get some time in when you can in the yard... they're attached to the power unit with a pintle and clevice, so you have a pivot point there, plus you have another over the front axle, which turns as well.

    Yup that's what I'm in. Been doing ok so far and have been finding areas where backing is unnecessary
