[1:12] Liebherr LTM 1090

Hello neighbours.

I'm Alwin from the netherlands. Unfortanly I can't write german. But i can read it as long there are no difficult words used.

Some of you maybe already know about my project. I talked about it before. But since the project has take a lift off a few weeks ago. I'm starting a page here also.

The orginal topic can be followed here. (dutch)

Hallo Alwin,

das sieht wirklich sehr gut aus !

Ich bin gespannt, wie es weiter geht !

hello everyone.

thank you for all the glamour.

@uwe P
We have met each other @ bemmel last year.
I will be there in bemmel this year also but I don't think the crane will be ready by then. I'm trying to get the boom working at bemmel. That's my target.

Still not sure it will cause a lot of small issues have to been solved before.

A double lift will give a lot of attention that's for sure.

*i know that your english ain't very well so i translate it by google/translater

Wir haben einander @ bemmel im vergangenen Jahr erfüllt.
Ich werde dort in Bemmel in diesem Jahr auch, aber ich glaube nicht, dass der Kran wird bis dahin fertig. Ich versuche, den Boom zu arbeiten bemmel erhalten. Das ist mein Ziel.

Immer noch nicht sicher, es wird viele kleine Probleme verursachen gewesen zu sein, bevor gelöst.

Eine tandumhub geben sehr viel Aufmerksamkeit, dass ist sicher.

2.7kg. Maybe it has to go on a diet but otherwise every kg here saves weight at mine contra weight.

Sanded down the plates to fit in the holes.

Well this is how i build the system. At the last picture you could see the damage which occured because of the little space within the parts. Well when the crane is working and needs it renovation it will be repaired or maybe i use a paint pen.

Hey.

Realy Great!!!!

hello uwe,

little bit late answer but picked up the project again and going to change a lot.

cabels are still the biggest problem.
going to build a couple of winches inside the upper frame to roll up the cables inside.

also the couplings between the dc motors and the mechanisme of lifting the telescopic parts where to weak.

got some nice cross couplings from fechter now. much stronger but still flexibel.

also gonna make the upper mounting plates for the telescopic parts. so side correcting is available also.

the ride chassis is the last part i will work on.

Hallo Alwin,

das mit den Leitungen ist sehr schwer zu Lösen. Du könntest

Leiterbahnen in den einzelnen Ausschüben einbringen.

Besser wäre es,die Motoren fest im unteren Tele einzubauen.

Dann kannst Du angefangen vom kleinsten Ausschub teleskopieren.

Vorausgesetzt alle Spindeln sind mit flex. Kopplungen ausgestattet,

die dann beim annähern der einzelnen Ausschübe zum Motor ineinander

greifen.



Gruß

update:

Excellent work!
I am building a 1:14 LTM 1500 8.1 and would like to ask you about your slewing bearing ("Turntable"): What is the outside diameter, and where did you find the parts?

I am really struggeling to solve this problem for my crane..
Thanks in advance! :-)
