Unimog U 2450

[efferman]

thanks for the link Dluders, but i think my 102x32 delivers enough grip. the ascending slope which i use is very slippery

[efferman]

Sorry for no progress for a long time. But i had some other ideas and no time for the mog. today i had take a look at the hydraulics from the steering system and get a shock.

The piston rod have a hole in the chrome. now i have no concerns, water is no good fluid for hydraulics with Lego parts. and now i have a problem. four cylinders and my steering concept are ready for the junkyard.

Possibly could use some really low viscosity RC shock absorber fluid. Shoulder cause any rusting with that solution an sorry to hear about your pistons getting all gunked up an rusty x.x. Maybe to salvage them remove all the none metal parts form the piston an get some rust remover an then put it back together? Least then they should still be useable for normal pneumatic use.

[efferman]

rust remover could imho not close a hole but maybe you are right with the pneumatic use. i will try it next days

[efferman]

Hi Guys, i have some wip pics from the crane for you. it fits on trucks with a width of 25 studs. The second Boom is not final. the connection between first and second boom is twisting under the weight (350grams) of the bug.

[olaf9198]

cool crane efferman and could you make instructions for that crane

[efferman]

Thanks

when it is done it will be a pleasure for me to make instructions

[grohl]

Looks well, seems strong.

[efferman]

thanks. I think in the borders of lego it is strong enough. to get it more stable i must use this Setup (first and second boom in one line) but this would not be the right for a mog. A real crane in this class would kill it with its weight this concept is more something for my Scania

Efferman, I always enjoy reading your posts. You are full of great ideas and your humility displayed in your posts is refreshing to see. You are truly a Technic innovator.

[efferman]

thanks

maybe i am full of ideas, but mostly myself is not satisfied with my projects. And to have so many ideas could get into a curse. I am building on a moc, have a new idea and begin with something complete different. Currently are 6 unfinished Mocs (U2450, Scania, Baja bug, Rennpritsche, Trophy truck, Little unimog) lying around me and hoping for finishing. the red Baja bug in the first crane picture is one of them. having problems with the shape of the roof is enough to pause the building process. i admire the guys which could finish their mocs in a straight row.

Great crane, eff!

I like how good it can fold.

[efferman]

Thanks Milan. The folding ability of a knuckleboom crane is a minimum requirement for me. it must be nearly like the real thing. Sorry TLG, but in this point the crane of the 8110 is a joke.

i differentiate in following classes.

minimum folding ability but very powerful

Picture source

full folding, most used crane in real life

Picture source

extraordinary, very strong and huge and to heavy for normal trucks

It must be nearly like the real thing. Sorry TLG, but in this point the crane of the 8110 is a joke.

Thats also my guide when I am building: Realism

For me, compared to the work of other AFOLs, and after all compared to the real life models, lots of mechanics that TLG make is a joke, not just the crane you mentioned.

But ok, we can't really compare TLG and AFOLs building approaches.

We will see how the rest of the 8110 truck will be, but I can imagine it will be far from what guys here can make in a TT races...again, TLG has a good reason make it like that.

Ditzj had a great inspiration for me, especially for a truck loader cranes, to be terminology-exact, knuckleboom cranes on a trailers has also great appeal.

I am enjoying observing your progress on knuckleboom cranes, in the near future I have a plan to make my first unimog with a good crane.

Keep up!

Can i race you?

I would like to biuld one too,i thought you are going to make a dozer next don't ask me were i found that from.

[efferman]

Thanks for your praise guys.

i have a little progress for you

The fly-jib is removable and the crane is above the turntables more or less in the final version. Only the pneumatic hoses must find their place and the way to my home

[Alasdair Ryan]

Like the crane is the 2 rams on the last section for extending?

(Like the crane in the box idea aswell )

The cylinders are moving/tilting the third boom. i make some closeups from the flyjib alone, that you could it see better

I'm not sure I understand why TLG's crane is seen as a joke. It is a simple crane, it doesn't pretend to be anything else. It is small enough as give some idea of the attachments a Unimog can take without being beyond the capacity of the compressor or the spending power of the the market it is aimed at, whilst bearing in mind the B model.

[allanp]

Agreed brickend. The unimog has alot of awesome new parts already, but in the future I really think we need some longer cylinders for this type of thing.

Thanks for the pics,i should of gone to specsavers

Brickend, no offence but my opinion about the 8110 crane is based on 19 years building Cranes in real life and so my leveling rule is maybe a little bit higher than them of other people.i know that TLG will never offer a crane that is in my eyes perfect. but the minimum requirement should be that the end of the crane can touch the ground without problems. At this time iam not sure if it can touch the ground. The 8110 is surely a gourgeous model with great ideas, and good to play for kids,if they could pay the price.

in august i purchase it, build it and then i will modify it to the point that it satisfy me. not more not less.

And then i use the tires for some big things

I completely agree about cranes and getting the 8110

.. except for the "building cranes for 19 years" part

and possibly not getting the 8110 because it is way too expensive for me right now..

[efferman]

Next Update

I have Build the front stabilizers added it to the Crane. 55 studs wide

And i have modified the first boom to get more degrees of moving. please compare

"old" more power

"new" more moving range

and i shrinked the width on the mainboom from mostly seven studs to mostly 5 studs. i hope you can see the difference.

"old"

"new"

[olaf9198]

jes efferman i can see the difference because the new boom is stands on breaking on the lower side
