Trailer Sliding Platform

[taquito971@yahoo.com]

In practice it will probably work. But in theory, if the 1" tubes are tightly toleranced to the bearing surfaces they will bind on each other because the rotation of the rollers will be fighting you.

That's harder to describe than I thought it would be... Hope you understand it though!

I understand perfectly. The roller diameter is 3/4", so with two 1" tubing it will total 2.75". That will leave me with a max of 0.25" of play to work with. So I think it would work without any resistance to the rollers.

We need a side view.

As the slide extends out more and more weight will be carried by the rear upper rollers and the front lower rollers. The former need to move with the slide, but the latter need to stay fixed in place.

I think the previous picture is a better design for rollers. Your using the rollers on the platform not the angle? So you will have to align the rollers when you slide the platform in? Still trying to wrap my brain around this. I will have to look at the draw slides I have.

Now I'm confused. I was thinking of only having 4 rollers on each side, on the same horizontal plane. The platform would roll on top of the bottom 1" tube that would be fixed. The top 1" tube would prevent it from tipping as it rolls out, which would also be fixed to the trailer. Does that make sense?

Here would be another option instead of using the angle iron for the platform. This would probably be better because the platform would need to clear my tailgate when it comes down, which sits about 1.25" above the bottom of the tub.

You are right. Did not think about that. It would be better for the rollers to be fixed to the trailer instead of sliding out witht the platform.

Sure, but when you pull the drawer out past say...the third roller there isn't anything to prevent it from tipping anymore. And if you are looking at a 1/4" play in the system it's going to bounce around pretty good too, when you pull the drawer out it will tip some, at least enough to take up the slack. In essence, the front rollers will roll on the bottom tube, and the rear rollers will roll on the top tube when you go past the center of gravity.

I think this would be a better option. The rollers will be fixed to the trailer by attaching them to a 1"x3" rectangular tube bolted to the trailer. It would be designed to slide out 75% of the length of the trailer.

Here's how I would do the slide. It's basically how the Engel fridge slide is designed. If you need help working out how to size stuff based on your load requirements, let me know.

Both look good. The first has fewer rollers, but more material. I like the second. A few more rollers but more simple to build. Now, what are you going to use to lock the platform, both open and closed

 

[ntsqd]

I've an idea that should simplify things, but it's going to have to wait a week as I'm outbound to central NV right now!

davegonz, That set-up would work as well. I see how the additional roller on the top section would benefit the sliding platform when fully extended.

OlympiaFJ60, I thinking about incorporating a lock/latch at the end of the slider. I need to do more research on what would work the best for this set-up.

ntsqd, I am waiting for your return to see what kind of simple idea you have.

 

[davegonz]

Here's another one I found..Don't know if it really works, but it's another idea.

Bed slide on craigslist

This might be your cheapest solution.
