Thank you!
With a short boom it should lift around 20 lbs max, but with the max boom that will be reduced to a couple of pounds I think.

This is one of the most eye catching parts, and it definitely is going to do that!! As always kerst, your work is above and beyond. Keep the pics coming.

Another step in the right direction:

As usual, a giant step toward great detail with excellent craftsmanship. That's a lot of parts to keep in alignment while soldering!

Thanks!
I used this setup for the soldering and I prefabricated the hinge points, brazing pieces of steel together.

The past couple of months I worked on the boom. By now most of it is ready. I am still working on the head and there are many details to be done, like the rigging, etc.
This morning I took the basic boom and fitted it to the crane for the very first time and it fits like a glove. That is a relief!

Wow, thats looking amazing.

Looking very nice.

Too notch skills you have. Love all the brass work.

Re: Demag TC 500 truck crane in scale 1/24
 

I rigged her up yesterday and tested her with 12 and 48 m of boom.

Fantastic !!! So beautiful model. Showstopper right there Kerst. i see big lift in the future.......:D

Re: Demag TC 500 truck crane in scale 1/24
 

Very nice. I see you didn't add any extra counter weight. Where you able to boom up from zero degrees?

Re: Demag TC 500 truck crane in scale 1/24
 

Thanks! That is right. there are no counterweights yet. It booms up without, but the outriggers are needed.
I have 2 more boom sections to add, turning it into 10' of main boom. Then I guess I will need some counterweights.

Kerst

Re: Demag TC 500 truck crane in scale 1/24
 

Very nice job kerst. You sure have a lot of patients to do these models. Ed

Re: Demag TC 500 truck crane in scale 1/24
 

Oh wow... what? I missed this thread completely!

What a beautiful truck and that boom is TALL! Super nice work... I've never seen such a project like this in brass. ;)

Re: Demag TC 500 truck crane in scale 1/24
 

That's beautiful!

Re: Demag TC 500 truck crane in scale 1/24
 

I finished the remaining pendants and rigged her up with 72 meters of boom. This turns into about 10' for the scale model. It needed 7 lbs of extra weights on the back to raise the boom. Otherwise it worked fine. I am pleased with the result. When finished the counterweights will be around 5 lbs, so I will need to make the extra outriggers on the back for raising the boom.

This is how the extra outriggers will look like:

Great job Kerst you haven't lost you touch keep up the good work. Ed

Hook block done!

I will make 2 more hook blocks, one with 3 sheaves and on with a single sheave.

Kerst

Re: Demag TC 500 truck crane in scale 1/24
 

That hook block looks amazing!
How hard was reeving that since it controls the lines that effectively?

What are the 2 ears at top of the block for?

Re: Demag TC 500 truck crane in scale 1/24
 

Now it makes sense to me. When I saw a cylindrical part, with notches cut into it, I was like,..............WTF is that for. Great work!

Re: Demag TC 500 truck crane in scale 1/24
 

Auxiliary outriggers
I spent the past couple of weeks fabricating the auxiliary outriggers. They are clearly needed for raising the more than 10’ of boom.

Kerst, amazing work, as usual! I have never seen auxiliary outriggers like these before. Very interesting.

Ken

Re: Demag TC 500 truck crane in scale 1/24
 

Totally missed this thread till now, so just read it completely through. Love every part of your work, Kerst!! Cool seeing first the cab raising slightly and then the boom going up with no visible play between the carrier and the upper of the crane. :jaw::jaw:

Thank you!

Re: Demag TC 500 truck crane in scale 1/24
 

Love that short video! The extra outrigger sure works! Can't wait for your next pictures.

Re: Demag TC 500 truck crane in scale 1/24
 

The next step is building a trailer for the counterweights and the boom. I choose a typical trailer used in the 70’s and 80’s for this purpose. It is a 4 axle Scheuerle trailer. I started a month ago and made some good progress.

Re: Demag TC 500 truck crane in scale 1/24
 

That is going to be a real interesting trailer. Is the rear self-steering or is it controlled by the front somehow?

Re: Demag TC 500 truck crane in scale 1/24
 

The front and the rear are connected and steer together, but opposite. The trailer is bi-directional.

Kerst

Re: Demag TC 500 truck crane in scale 1/24
 

All mechanical linkages? Look forward to see how you make that work.

Re: Demag TC 500 truck crane in scale 1/24
 

How old is that trailer design? Got to looking around the internet to see if I could find some info on it and there is almost nothing. Found one picture on the Scheuerle company web site on a history timeline that says it was introduced in 1949!

Found a guy on a german modeling forum who built one in 1/16 scale and it appears his has crossed chains running underneath the trailer to connect the front and rear bogies. Is that how yours will work?

Looking forward to seeing more photos of this build.

Re: Demag TC 500 truck crane in scale 1/24
 

that is correct. The design is from 1949, but most were produced in the 50's 60's and 70's

This is how the original works, but I will use steel cables.

Thanks!

Kerst

Re: Demag TC 500 truck crane in scale 1/24

Re: Demag TC 500 truck crane in scale 1/24
 

A short progress report. I worked on the steering mechanisms of the bogies. It works fine now. next is the connection between the front and rear.

Wellcome to the heavy haul side.......i'm sure you'll like it :) I like your work and always looking forward to see more.....and more.

Re: Demag TC 500 truck crane in scale 1/24
 

This just keeps getting more and more wicked!

Will the mobile crane be able to transport the boom trailer, or is there going to be a tow-rig for that?

*looks at your crane, back at my crane, at your crane again* Maybe it's a good thing i don't have better tools yet... i don't think i could handle this much awesome.
