Machines | Walk-Around Of An Autocar Tranfer-Dump Truck
videos | at work | information | view | construction
This 1986 Autocar AT64F Transfer-Dump Truck belongs to M&J Transportation Services. The reason for posting this video, besides having another "walk-around" type video, is to show people the mechanical systems of a truck like this. In another video that I posted last year (Transfer-Dump Race: The Complete Run), I got a lot of comments from people that had no idea that trucks like this exsisted and were curious to know how they worked. I've seen trucks like this my entire life in all of the states that I've lived in, and I assumed they were common everywhere. Guess not. One of the things that got the most attention was the system by which the driver can back the truck up from the rear of the truck to hook up the towbar of the trailer to the pintle hitch. This is done when the driver leaves the transmission in reverse and shuts the truck off. The driver then goes to the back, lifts and aligns the towbar to the hitch, then pushes a button under the lip of the dumpbox 1:15. This activates the starter motor on the engine of the truck. Since the transmission was left in reverse, the starter motor then turns the engine (without actually starting it) and the truck backs up to the trailers towbar. In my opinion, a brilliant solution to the problem of bringing the two together. Note: I know that there are fully automated systems in Europe and Australia that allow the driver to hook up to their trailers without having to get out of the truck. For whatever reason, that system is not used here in the states. No need to tell me or ask me why we do not use them here. Another system which is shown here is the drive mechanism which moves the dumpbox from the trailer into the dumpbox of the truck so it can be driven to where the material is needed. The system on this truck is a pneumatic one where compressed air in the 4 tanks under the trailer's dumpbox is used to supply air to the pneumatic drive motor that moves the box. There are also electric and hydraulic drive systems that do the same function. To see these systems at work on a truck similar to this, watch my video Transfer-Dump Race: The Complete Run. Hopefully this video answered the questions of how trucks like this work. Thanks for watching and reading. Shot at the Truckin' For Kids Truck Show at Irwindale, California on October 6th, 2012.

that trailer is a JOKE.. it's a old fruehauf trailer frame and they tried to make it look like a updated superior.. sorry but it looks tacky.

I would much rather have a pup dump trailer than go thru all of that connecting and unconnecting and it would be safer for the driver also, and less time consuming...I reckon I dont understand the concept behind a transfer box, would someone explain the concept to me please? compared to a pup dump?

That Autocar got cut up for CARB

Of all the custom transfer trucks, this is the one espeescotty post on yuotube....unreal.

Until you pointed them out, I hadn't noticed that they were hydraulic quick connects. I don't know.
-
Any reason for using hydraulic quick connects instead of standard glad hands for the air hoses?

Its a nice transfer... But all the good times spent driving the two red Macks are priceless...... By far some of the best times of my driving career... Thanks John, Hill-Billy Mike and Sheri...

I've seen that ride before! I met him head on when I ran a load of rock to Ca. Clean truck.
