Hi,

Need some guidance on a wacky idea of mine.

i plan to convert my 52 gmc 250 series to a dump bed. Given i don't have metal tools readily available nor the skills, may have a local Fab/Welding shop do the work. Is it complicated? Any ideas on cost - rough ball park ...100's of green backs of 1,000's?

Prior owner of my 52 gmc threw in a new PTO unit. Guess that is a whole nother ball game to get that installed.

Appreciate any guidance you all offer.

There are some great photos of the dump bed platform on "BigTonka's" site. Look At "hydraulics"

I bought a "kit" from Northern Tool once to make my flatbed dump. It was an electric hydraulic pump, a scissor mechanism, the ram and hose. I ended up having to fabricate my own hinges because the ones in the kit didn't work with my frame/flatbed. I also don't like the way the scissor mechanism works - the ram is fighting against itself when you need the most power (right at the start of the lift)

That said, I would buy the electric hydraulic unit by itself. Then I would fab up a twin ram set-up like on "Big Tonka's" site mentioned in the above post. Make your own hinges and get the hydraulic lines made to order at the local tractor dealer and you're good to go.

I love having a dump bed! When I go to the landfill and park next to a guy in a 2011 Super Duty who is shoveling grass clippings out of the back, I love to see the look on his face when this old truck starts dumping!! Priceless!

To bad we didn't live closer as I am removing the dump bed from mine. They had welded a frame on top of the original frame . They then built a second frame to that that pivoted off the end on a large pivot shaft. The box was operated by 2- 3" bore hydraulic cylinders. There is a few pictures in my albums link below. Anyone that wants the equipment is more than welcome to it.

Hi Rob -

From 52__Ton's description, we have a similar setup.

Where the red shirt is attached are the pivot points for the dump. This whole assembly was welded to the frame.

Better view here:

The original cross members were welded to some thick C Channel shown here, the bottom left you can see where the big pins are inserted to pivot on the base:

Whats nice is that it makes the whole bed easily removable by pulling 4 pins. (And 4 huge guys!)

The only drawback is the whole bed assembly is raised 2" and the leading edge of the fenders catch the running board. I'll have to do something about this when I reassemble.

Yes Bigtonka, mine was very similar to that. The frame on mine is a little heavier but everything else looks very close. Mine is a Oshawa produced 52 GMC 9430 that was used in Saskatchewan to haul grain.
This link shows the frame and bed during demolition with hydraulics removed.

Hey Rob's Dually...I read your question with interest as truck bodies and equipment have been my livelyhood for over 45 years. Given what you said about the skills level and tools your best bet by far is to buy a quality pick up hoist. Quality is the key word here because everyone who gets price-sucked by N-H stuff ends up regretting it just like Harbor Freight crappo tools.

Send me a private e-mail and I'll help you out.
