Re-rebuilding my trailer....

[DeathBlade556]

Well, I'm rebuilding my trailer for the third time, with a dump bed this time. No more shoveling junk for me! :003:

Pics and more detail in a minute, but first some quick questions

the frame is just hot rolled angle and I have three sheets of pressure treated plywood I know this new pressure treated stuff eats fasteners that aren't galvanized.
Would it eat the angle?
Should I just get some exterior grade and coat it with some heavy epoxy paint?

Second I was going to make my uprights with 2"x2"x.125" square tube and I should of had two 20 foot sticks laying around from building a gate, but it must have walked off. And I need to finish this this weekend so I dug through my metal and found some 2x2x.125" angle and some 1" .120 wall 4130 tube sections and I got thinking could I weld the 1" in between the legs 2" angle, would that and any strenght?

The axle is the back ground fell over a few minutes after this picture and I tried a good half dozen tries to push it back up the hill, before going "frak this sisyphus shit!" and pulled it up the hill with a tow strap.

And a load of ten 20foot sticks of 2x2x.125" angle 15feet of 2.5x2.5x.25" tube and some 3" channel and 5 feet of 1 1/4" sch80 black pipe and its time for trailer 3.0!

Now on to the build

I'm making it a bit larger, going from 55"x38" bed to 64"x44"
The bottom frame is 3" channel with 2.5" tube

The dump bed is a bunch of 2"x2"x.125" angle doubled up back to back in a 'T' with 1.5"x1.5"x.125" welded in as cross members

You can see the open gap in the frame where the ram will sit. Using a 4" bore 3.5" rod Ram with a 18" stroke

Cool build. I built a scissor lift for a truck last summer. Just watch your angles on the cylinder.

A bit of an update.

I haven't gotten much done for the last month so I got the ram in and tried it with and and ta da it works. Then I started doing the math and with the 4" ram it will push about 22,000lbs a bit to much so I'm looking for a 2-2 1/2" ram instead. (some good info here, http://www.surpluscenter.com/Hydraulic.htm )


Here is how it sits now

The ram mounted, I think I need to mount it a more of a angle

I hooked if up to my air compressor and it has just enough power to tilt the bed

And while I was at harbor freight the other day I saw somebody had returned one of their truck cranes they normally cost $159 it was priced at $90 because it was a return. I talked them into allowing me to use a 20% coupon on it so it was $70 :023:

But now I don't know were I want to mount it.
Its either
A. on the tongue of the trailer
or
B. on the side of the trailer

I'm leaning towards B but I'm 50/50

A

or

B

That's one hellufva actuator. I would put the crane on that end so you can put engines axles and stuff in the trailer easier. I would also put a trailer jack on each rear corner to stablize it. When your using the crane.

[DeathBlade556]

That's one hellufva actuator.

I know I need to find a smaller one with the same stroke, and thats harder than I thought when looking through surplus.

Now I just need to decide If I want to use a lunette or the ball hitch I have now.

[jim91303]

keep the ball hitch. the lunette type bounces and jerks the tow rig at stops and goes.
