I hope you don't mind me doing this post in English. My German is not good enough.
Now that the LTM1800 is more or less finished it is time for a new project. I have been thinking about which crane to build for quite a while and I actually started with some parts a few months ago before deciding to actually build this crane.
It is a German built Demag crane on a Faun carrier and was produced in the late 70’s. There are still some around, I know there is one at Inland Crane hire in Idaho.
On this page you can see the TC500 ready for action: http://www.heavyequipmentforums.com/showthread.php?14902-Bridge-replacment
Van Seumeren also had a few: https://www.flickr.com/photos/73498813@N02/6641955839/

The Demag TC500 is the successor of the TC400 and is basically the same crane, just a few reinforcements and more counterweight and is rated at 125 metric tons capacity.
Here two pictures, one from the back of a leaflet and the other taken by myself. I will build the version with the very low-line carrier cab.



Here are two pictures of the rims:


The tires come again from the All American Toy Company.

At the moment I am working on the drive axles, which is a challenge, because space is very limited. I decided to completely build the axles myself.
Here are some pictures:




I made the drive shaft between the two axles. This was tricky, because they are very close together.

I made some progress with the wheels. The tandem axles are done and I have been working on the other wheels. These are the three axles with single tires and one of the three axles is driven. For these I used brass, because it is so easy to solder and machine. I will focus on the driven axle next. It is very similar to the rear axles.
The picture shows all the front wheel parts in various stages of assembly. The bearings are 14 x 8 x 4. I got a whole lot of them for very little money:


The tandem axles with walking beam suspension:


Here is the frame, made of AL:

I made some nice progress, although things are not as finished as they seem. The front axles are basically done and today I made good progress on the third axle. I still have to finish the suspension and the steering.

The beginnings of the cab are here:

I also started on the outrigger boxes. They are pretty straightforward. I decided on Steel and I brazed them together. Now they are definitely strong enough. The second picture shows some parts added using solder. They need to be cleaned up a bit and they are ready. Next are the outrigger beams.

Faun carrier

The outrigger boxes are ready and bolted to the carrier. Next will be the outrigger beams. I am also thinking how to build the gearbox and transfer case and which motor to use. There is not a lot of space, so they need to be designed carefully.






Note: The third axle is missing.

Very nice work.

But - isn't the cab very low, compared to the two pictures in the first post?

Transfer box

In the last couple of weeks I have been experimenting with a planetary reduction, which I got from a small geared motor. A lot of trial and error! The outside diameter is 22 mm and all the gears are steel.
The trick was to incorporate it in the transfer box. I tried a lot of different setups, but I think I found a setup that works. The transfer box will have two speeds (direct and very low) and front wheel drive can be engaged or disengaged. The real one has an inter-axle diff, between the rear axles and the front axle, but I couldn’t find the right planetaries to accomplish that. It would need a 1:2 ratio.
It turned out nice and compact. But it hasn’t been tested yet.

During the past couple of weeks I worked on the universal joints. I always make them myself, mainly because they need to be very specific in size, but also because good quality universal joints are very expensive. The final assembly of the joints is always tricky, because I solder the pins (1/16" diameter) in from the center and the solder easily flows in the wrong spaces. It needs to be heated just enough for the solder to flow, but not too long. I had a cup of water handy to cool it down quick once I thought it was done.

In the pictures the motor is directly connected to the transfer box, but I might add a 2-speed gearbox. I want to first try out the speeds and see if this is the right motor, etc.

I did some work on the cab. I added the doors with homemade hinges. They still look clunky, but this was the best I could do.



I also installed the motor and a separate small gear motor to lift the counterweights. This needed a bit of thinking, since room was very limited. The 2 pictures show it both in lowered as in in raised position.

Hello Kerst,

I find the doors and the hinges great. More than perfectly the idea is for this raise of the ballast and before all things the technical conversion. Simply brilliantly.

In the past couple of months I did all kinds of little things, including optimizing the steering, working on the space in front of the third axle, the levers of the gearbox and some other details.





Here is a short video of the steering in action: https://youtu.be/ObYaSMiSlfU


I also made a box for the crane with space for the crane itself and the boom sections.



I wish you all a Happy New year and see you at the Cabin Fever Expo!

I started work on the outriggers. here you can see the structural parts of the outriggers, steel, brazed together. I will use hand operated screw jacks for the vertical movement. there is too little space for a motor.
