Today I was busy with the frame. Unfortunately, I also discovered the first error in the drawing. See pictures below.

Great craftsmanship there Dutchy – it’s coming along very nicely.

Well it didn’t take you long to start finding errors in this one too.

But I’m sure it’ll be fantastic when you’re done anyway

That is looking good. They also have the springs in upside down. I think that is lack of knowledge on the people drawing up the plans. That is a Hendrickson Spring walking beam style suspension. It is made for off road and heavy duty applications. The ends of the springs should have mounts on the frame and the walking beam mounted to the center of the spring.

select straight truck, dump, tandem, 46,000 and it will give you a picture of the suspension you have.

Thanks all for comments.

Bruce I,m glad @#%$#& with your information! Although I am no expert in this field I sould have seen that it was wrong. I didn’t. Now I know it is wrong my brains will trying to find a solution. That will be hard because the springs are part of the construction stability. When I change it the stability is gone.

I’m sure that is why the plans are the way they are. T&J couldn’t figure out how to do it so they took the easy way out.

Well Dutchy this opens a whole new can of worms, and I thank Bruce for this info, I did go to the Hendrickson site and for sure he is spot on.
Not sure what you are going to do about it , If it was my project I would continue on with the plans and if you have anyone visiting to inspect the suspension on your project you can tell them the plans were incorrect .
wonder what Toys and Joys will have to say about it?
I thank Bruce for pointing this out.

I had a feeling this didn’t look logical but really hadn’t looked that close, but once you see the real thing it all come together me thinks?

How about turning spring over having two mounting points to frame.
Have a pivot point at bottom of spring.
Now wheels will roll over rocks independently cool.
This is the way it works on the real dump trucks.

Now you’ll have the only one that really works right, till I build mine that is . lol
Don’t you love it when a plan comes together.

I like it that you guys are thinking about solving the spring problem. Among other things is that one of the things is what LJ make so convenient and supportive. Thanks guys!!

Today I made the decision for this truck not to change it. If the truck is finished it is almost to see. It is unfortunate but I can live it. There are more important things in this life.

You could change it over to the more modern rubber suspension but still needs the be mounted the same.

Tried to delete but it wouldn’t let me.
I should have figured you were way ahead of us on the build.
It’s a model and the springs won’t be seen much behind the wheels any way.
Still will be cool when you turn it over and see all the workings under neath.

Keep up the great work it’s going to be one really nice truck!!!

I agree I would stay with the way T&J has it. To change would probably require changing height of front suspension also. The only person knowing will be you.
I am looking seriously at the T&J garbage truck plans. Just need to finally pull the trigger and order them.

Bruce,
When you order the garbage truck plans and you have made the truck you probably are addicted and caught in the nets of T&J. They like fishing
