Krupp 180GMT 1/20
I built this crane years ago and it took me a long time to finish and in a sense it was never finished. I painted it red, but I was never happy with the result and over the years I made lots of small repairs and alterations.
During the last day of the Cabin Fever Expo something broke and in order to repair it I needed to take the whole thing apart and then I decided to just do it and repaint it. It took me about 6 weeks of cleaning, sanding and re-finishing and here is the result. i also added dome more details.

Very Nice. Did a nice job both times. Love to build one. Someday HaHa. is there a build thread?

Re: Krupp 180GMT 1/20
real nice work!!!
where in NY? |
Re: Krupp 180GMT 1/20
That is a very impressive build and a great paint job.

Re: Krupp 180GMT 1/20
WOW what a change. I wasn't aware that you broke this at the show.
I think that's my morning tea on the table:p |

The actual repair took only 15 minutes, but i had to take the whole thing apart first. It gave me the chance to fix some other small details, but i had to promise myself not to do anything major, because I am always tempted to rebuild the whole thing and that would take me years. I have considered rebuilding most parts of the upper including the boom! Kerst |
Re: Krupp 180GMT 1/20
Hello Kerst,
The crane lookes very nice. I already saw a little movie of it when I was reading your buildreport from the Liebherr and watched some movies on Youtube. Do you have some more pictures of the crane, maybe when it was disassembled? I am currently drawing a Liebherr LTM1160 first generation (scale 1:14,5) that I want to build. Still have some issues whith the outriggers. They have to lift a lot of weight, approximately 40 kg without counterweight, and hold even more when I am operating. How did you make the outriggers, do they actually work and how much can they lift? BTW I got the tip for your buildreport on the Liebherr from Eef, who is a collegae if mine. |
Re: Krupp 180GMT 1/20
That crane is Bad A$$!!!! That must have taken a lot of calculating and trial and error building to get it right!!! Very cool and i love the new yellow paint!

Re: Krupp 180GMT 1/20
Thanks , everybody for the encouragement and the kind words!
I have no pictures of the building process, just a few detail pictures. http://farm9.staticflickr.com/8154/7...acc26b98_c.jpg http://farm8.staticflickr.com/7097/7...1fbec96c_b.jpg I will try to make some when I have a moment. Kerst |
Re: Krupp 180GMT 1/20
Wow that thing is serious......great job on building a serious piece of machinery.

Re: Krupp 180GMT 1/20
Hello Kerst,
Thanks for the nice pictures. They give a good impression of the crane. It's a nice piece of work. |
Re: Krupp 180GMT 1/20
wow that is just breath taking!!!!im in shock over the details and robust it looks...congrats on a job well done!
|
Re: Krupp 180GMT 1/20
That's an amazing build! I'm impressed with the detail, it's a work of art! I also like the yellow paint job, it looks great!
|
Re: Krupp 180GMT 1/20
It looked incredible before, now it is just stunning! That is a one-of-a-kind crane! The yellow and black paint job is very classy, and makes it look ready to go to work! :D
What's next? |
Re: Krupp 180GMT 1/20
Since I started experimenting with RC control for my truck I got the idea to do the same for the Krupp crane.
There is no space on the crane itself for the batteries and receiver, etc. I decided to build a counterweight trailer with a hidden space for the battery, speed control and receiver and of course for the counterweights. I already had most parts and it is going pretty quick. Here are some pictures of progress so far: https://c1.staticflickr.com/3/2493/3...e022f587_b.jpg https://c1.staticflickr.com/3/2591/3...672d3f8e_b.jpg Kerst |
Re: Krupp 180GMT 1/20
Hi Kerst
Looking good should be interesting. looking forward to the finished result if your crane is anything to go by it will all look great.:) |

Re: Krupp 180GMT 1/20
Very cool!!!
Are you going to rc all the functions, or just do like drive/steer and still have to hook up a breakout cable to deploy the rest? |

It will be only for the driving functions. I just tried it out and it worked beautifully. Kerst |
Re: Krupp 180GMT 1/20
The counterweight trailer is more or less finished. It includes the RC equipment and battery.

Re: Krupp 180GMT 1/20
Another video, this time with more space available and driving at full speed.

Re: Krupp 180GMT 1/20
That's really awesome!

Re: Krupp 180GMT 1/20
After 4 years I decided to upgrade the RC controls. I learned a lot while building the Euclid and i am confident to make all carrier functions RC controllable. The Krupp has a powershift gearbox with 3 speeds and an auxiliary box with 2 speeds. The transfer box has a differential which can be blocked. That takes 5 channels. It will be fun to be able to control all these functions remotely.

Re: Krupp 180GMT 1/20
Very tidy and orderly installation. :cool:
|
Re: Krupp 180GMT 1/20
All the gear has found a place and now I need to "cover it all up" The first test run was satisfactory.

Re: Krupp 180GMT 1/20
That is some great engineering I like these crane builds...can't wait to see it together.

Re: Krupp 180GMT 1/20
The rebuilding is complete!
After I rearranged the carrier and made all functions (except for the outriggers) RC controllable, I started work on the upper. I was never happy with the upper and I decided to take all the motors out and replace them with new ones. I also changed the telescoping mechanism and installed the motor and spindle in the boom. That is a great improvement. The hoist also uses a spindle, but a better one than the old one. The counterweight has a motor inside and this way it can attach itself to the upper. All together there are 6 functions. Since I have only 4 feeds I had to add 2 switches on the upper. With all these changes I gained a lot of space and there was ample space for a battery for the carrier. It connects with a plugin cable. With all this rebuilding I tried not change the parts that worked well. I am pretty happy with the result, although some painting is needed, The motor compartment of the truck: https://live.staticflickr.com/65535/...93ce78e2_b.jpg The new swing motor and the 2 motors for the winches. https://live.staticflickr.com/65535/...b435f68b_b.jpg The boom hoist https://live.staticflickr.com/65535/...b2ea37e6_b.jpg Here a comparison of the old and the new. https://live.staticflickr.com/65535/...81babe35_b.jpg The other side. Lots of electric connectors. The battery is connected via this little storage box next to the hoist cylinder. https://live.staticflickr.com/65535/...2a886fcd_b.jpg Kerst |
Re: Krupp 180GMT 1/20
For the outriggers I have a solution. I can use the outlet for the counterweight for a small geared motor to activate the outriggers.
https://live.staticflickr.com/65535/...3b8b01ee_b.jpg This is the console for the driving functions. The left lever is for the powershift main gearbox, the right one for the acceleration and steering and the top right toggles control the transfer box low-neutral-high and the diff lock in the transfer box. https://live.staticflickr.com/65535/...05bd6367_b.jpg Here some more pictures: https://live.staticflickr.com/65535/...d21b976c_b.jpg https://live.staticflickr.com/65535/...680fd057_b.jpg https://live.staticflickr.com/65535/...44610dd5_b.jpg https://live.staticflickr.com/65535/...e018fd91_b.jpg Kerst |
Re: Krupp 180GMT 1/20
That crane is a true work of art, nicely done...
