[TC22] Mini Mobile Crane

[TechnicRCRacer]

I want to participate in a contest again, I can't even remember the last time I joined...

 

Anyways, I chose to do a mini mobile crane since the new small turntable parts encouraged me to try something new. The vehicle will almost max out the build volume and I aim to keep it at 17x39x15 (9945 cubic studs). I plan to add an extending boom, a fake engine, HOG steering, a lifting mechanism for the boom, and turntable rotation. Here is my progress:

Progress!

 

Mini fake engine installed and working, front axle added, rear fenders added, and turntable secured.

Nice start!

How do You plan to connect (brace) crane to turntable?

I plan to plug it in to the top holes of the beam frame and brace it via the 5L lift arms on the sides.

 It looks great already. Do you know the part number of the gray curved gear racks?

5L lift arms

Halfbeams? It doesn't look, that there could fit fullbeam.

You’re right, I didn’t pay much attention to that. I will use 5L half-beams.

I reduced the width to 13 studs since the original 17 stud width made the vehicle look ridiculous and reduced the usable height for the crane arm. I think this looks a lot better. Thoughts?

I attempted making the boom but it didn’t work out. The reduced width allows me to make a better boom and that is my next step.

[Jurss]

This looks more proportional.

Looking good! I also found 13 studs wide to work well for my mobile crane.

[Akassin]

The width of 13 studs looks more proportional. Are you using some real crane model as an example, or is it a sample image of a mobile crane? I look forward to continuing

[Lasse D]

Nice progress. Have you considered making the pistons move realistically? That is, with the outer two and inner two moving in pairs?

[TechnicRCRacer]

Update time!

I added the crane component. Here is the crane fully raised and extended. There are knobs in the back to control everything.

Finished model!

I put the model details and more photos on the entry post.

I’m happy you were able to finish it. Great job!

Interesting retroish (steramlined) design at some sections.

My building style seems to have evolved to reflect retro stylings. I think that design language is really neat.
