Who knows dump beds?
 

A guy was just here to buy some wheels from me and he had a truck with a dump bed. The truck was a manual with a PTO driven pump for the dump. This is the way I've always seen it. But... what if you wanted an automatic? How is it done in that case?

Re: Who knows dump beds?
 

With an Automatic you just use a pump that is self contained. (just like the ones on lift gates,fork lifts, and Suspension set ups) It usually runs a 12v motor on the end of the pump to drive it.

The way I have seen it would be a hydraulic pump that pressurized 1 single line to go up and then hit the switch the other way and let the weight of the bed bring it back down. (1 pump, 1 dump, 1 3 way switch, 2 hydraulic lines) You can either buy these pumps with a number of different gears in the pump head or you can use one from a lift truck. depending on which you use make sure the cyl and hoses match the pressure it puts out.
I have seen 1000 psi on lift gate pumps, 2-3000 on suspension pumps, Custom pumps and some oddball ones I have seen as much as 6000.

Hope that helps..??

if you have an automatic 4X4 with a 205 transfer.You can still use a PTO

Agreed, I forgot about the obvious... duh.

If you have an automatic transmission 4x4 and a 203 tc you can run a pto also. As another alternative you can run a motor driven pump.

I would use http://www.loadhog.com/YourTruck.htm i like there kit since it uses air and you can't tell its a dump bed truck tell you lift it up.

Well, the truck is a 2wd, but my mind changes more than a woman in a clothing store, so this all might end up on a 4x4 at a moment's notice. Thanks for the info guys.
