LTR 1100 telescoing boom system

[xchvcwryb]

Every crane should have a giant to keep it oiled.

Still squeeks though...

ok.

[rctruckclubsuisse]

the telescopic boom is always the most complicated part to build in a RC crane...but your system seems very good, simple and functional. cheers from an other "crane builder"

Is this one homemade? How does one go about building one? I am trying to fry up a way to do it.

Thanks glad you like it.

Yes it'shome made, Lathe and milling machine in my workshop.

I used the Liebherr product ref for the LTR as a guide. Just used a bit of licence in the details.

Quite a few porblems to over come with the way the telescoping operates.

Can you how its extending and what you are doing by hand while this is going on, i am trying to sort out an extension boom for a project and this looks like the key

Hi Crash5291,

Screws are was to 'pin' each section to the next section to be extended.

Telescoping is by small electric motor and ball screw.

Hope this is of help.

Indeed it helps thanks

Great to hear you want to build a crane. Will it be a Liebherr??? The boom I had made by a local engineering firm, it's two folded 'U' sections welded together for each boom section.

Hope this is of help.
