Vintage cable end dump trailers?

[Espeefan]

As an alternative to hydraulic hoist end dump trailers, I've been scouring the internet for information on the old cable end dump trailers. They were trailers from the '50s and earlier that were dumped using a winch on the back of the truck pulling it. The winch would pull the trailer axles forward, and they prettt much seem to ressemble a frameless end dump trailer, except for the obvious lacking of a lift cylinder. Problem is I can't find much info on these types of trailers. Is anyone familiar with these old trailers? I'm trying to find more photos and information, but it seems non-existent!

Hello Nathan I drove one of these trailers. What do you kneed to know? Ed

Hi Ed, everything! Really, I'm most interested in the cable routing, and how it is routed around the 5th wheel plate. I've seen some trucks dumping trailers, with the trailer turned 90 degrees to the truck. There must be some sort of pulley to allow the cable to make a 90 degree bend. Do you have any photos of cable dump trailers?

Nathan I tried to find some photos ,even tried a search but nothing the place that I drove for got bought out. The cable went under the fifth wheel to the trailer and if that cable broke it was quite an experience especially if the box was up. There was a guy on ebay selling Smith Miller trucks with a cable dumping the trailer with one of rc4wd winches. After the cable lift they went to a deal were the pto was on the tractor and the pump was on the trailer with a whip connecting the pto to the pump. You would jack-knife the tractor then connect the whip between the tractor the trailer. With these you had to be careful when you drove them that you did not jackknife or the whip would come unhooked. Hope this helped you if I find anything in my travels I will let you know and if I can help you with any more info don't be afraid to ask. Ed

Ed, thanks for the information. I have seen the Smith Miller cable dump trailers. I honestly didn't know such trailers even existed up to that point, but it got me thinking about trying to build or modify one of those trailers for RC use.

I can only imagine how wild it would be to have a cable fail, while lifting a loaded box! Ouch. On the 1:1 trailers, I assume they had multiple blocks and tackles, with pulleys to get a proper mechanical advantage? Did the cable connect to the trailer frame, or to the front axle of the trailer?

Yes, please keep me in mind, if you do find some photos of these old trailers. If I can get enough photos, perhaps I can actually try building one. It would be a neat alternative to running a hydraulic system. Plus the vintage factor is pretty cool.

Ed, do you recall the brand name of the cable dump trl you pulled? That would make the search for pics/info much easier... cable dump trailer is not showing anything, must be some other namesake for the application.

Espeefan-check with 9Wmonighan. He converted his Tournarocker into R/C

Perhaps an avenue of research could be to ask the guys at HCEA (Historic Construction Equipment Assoc) http://www.hcea.net/ There is probably a member that has one and might help. Hope this helps.

Thanks guys. I have been searching for a couple days and I have only found a few photos. I actually found some old brochures for these trailers, listed on E-Bay and some other E-Bay knock off. Havne't bought them, though they would be handy to help build a nice replica of such a trailer.

The only brand I have found so far is Hobbs Schonrock. There may have been others.

These photos aren't much to look at. Can't actually see the winch cable and pulleys all that well, but they did exist. I'd like to build one, if I could.







It's an easter egg hunt!

Nathan I'm not sure but I thought I seen somewhere Fruehauf had built one. Also look for Trailmobile, they were the same dump trailers.

[Espeefan]

Thanks Craig. Maybe I'll try some searches under that.

Nice find Joe!

[Espeefan]

Joe, awesome find! That will help me out a lot! Thanks for putting the effort into finding those prints. Especially the 5th wheel plate, with the pulley and cable routing. Now I might have a fighting chance of replicating one of these trailers.

[Lil Giants]

You're welcome Nathan, it peaked my curiosity too... I got a lucky click on some PDF's that appeared on one of many google links I looked at.

[Espeefan]

Well thank you Joe, and to everyone else who responded! Now I just need to find some photos of winches and how they mount them to the trucks!

A wdc winch should be stout enough for something like this?
