[TC5] Crane Truck

[LegoDejc]

This is my Crane Truck made from set 8049: Tractor with Log Loader.

I found out about this contest a bit late.

I worked really hard for the last two weeks, every day from 3 to 4 hours.

Leftover parts: 22

It features following functions:

-Steering of front wheels by rotating cog wheel on the back of truck.

-Stabilisers which are moved outwards by pneumatic cylinder.

-Pneumatically moved crane.

-Both pneumatic functions are operatable inside second cabin. Pump is positioned on back below truck.

-Second section of boom is operatable by light above second cabin.

-Lifting rope with a clutch.

-Manually rotated crane.

-Openable doors on main cabin.

Hi Dejc!

What a great job you did with the crane! I love the way you manged to make a whole cab with the limited number of lime pieces.

Nice job on the crane arm, its very functional.

Can you explain how the stabilisers work?

Zblj is right, nice achievement with such a limited asortment of pieces. The lime cab is really beautiful - I love those mudguards pieces at front. The arm looks a bit weak, but I guess you squeezed the best out of what you had! I am also interested in the mechanism for the outriggers.

Thanks to both of you!

As a machanical engeneer I always speak with drawings and 3D models, so here is the mechanism.

Between tan colored pegs is cylinder which moves otriggers.

The red beams are also guided round and round, which isn't shown here.

MajklSpajkl: as you see I used almost all bricks available.

I guess this was the main draw for this competition, for builder to show how inventive one can be.

So, I was jumping between functionality and aesthetics, and decided for functionality first.

Actually, with only one more red beam of 15 length, the weakness look would vanish.

With all the respect for lego builder of original set, also there I had the first impression that log loader is a bit weak.

But now my opinion is that this set is one of the best in years, especially because it uses pneumatics, which I absolutely adore.

Nice idea, don't get me wrong about the weakness of the boom, it wasn't ment as criticism at all - it is a marvel what you've managed to pull out of this set!
