Kerst, this has to be one of the best threads on this Forum. Your model engineering is absolutely first rate. TM

Thanks for the compliments! It is great to have a forum to share progress!

Last night I put it all together somehow and tried it out. I am not sure if the motors for the winches will be strong enough under load, but that will need further testing.

Progress has been slow during the summer.
I mainly worked on many details and little improvements everywhere.
On the upper I added 3 outlets, 2 in the front and one in the back for functions like the telescoping and luffing winch for when the derrick mast is attached.
I also added a couple of switches ( a toggle switch and a 3 position rotary switch) on the upper (2nd picture) to switch between functions. I have only 3 2-pole circuits coming through the slewing ring. This way i can switch between functions.

I spent the past month figuring out the mechanism to extend the 3 boom sections.
It is somehow based on the Liebherr system, one section at the time. I use a spindle, which propels 2 pins, which can hook into the bottom of each section and push it up. The whole assembly can rotate and with 3 positions available I can choose which section to extend. the motor is mounted on the side of the boom where the real one has an oil tank for the same function. Once in place the sections get locked manually.

I worked on the boom quite a bit. The telescoping mechanism is ready and I did some detailing, which is almost finished.
Next I will be testing the boom and getting ready for the Cabin Fever Expo in January.

I love this project Kerst. I may have missed it previously but do you have a livery in mind or are you going to paint it in Liebherr yellow?

I enjoyed the Cabin fever Expo tremendously. It gave me the chance to try everything out, play with my cranes and meet lots of great people. It was a great weekend, but afterwards I had to catch up with a few other things, so I didn't have much time for the LTM1800 till about a week ago.
I started working on the counterweights. I make them out of AL, which is a bit on the light side, but the whole crane turned out a bit too heavy, so that compensates nicely and AL is easy to work with. The total weight of what you see on the picture is around 14 Lbs.
It is an easy job, but time intensive with lots of (hand) sawing and lots of milling.
