Lego Technic Forklift SNSC Zoomlion MOC

[Danifill]

Hello! This is my new creation. It is a forklift that nearly copies the real one despite several moments like unpaired front wheels and proportions in some places. So, it has 4 functions that are controlled with one Buwizz and a Lego receiver: drive (Xl motor), traction steering (servo motor), fork lift (M motor) and fork tilt (2 pneumatic cylinders, 2 L motors for pneumatic pump and switch). It can lift up to ~900 gramms, in video I used two filled battery boxes, which weighs ~200 gramms. I use a pulley system for lifting. Also, it has kind of an interior with a decorative steering wheel and a seat.

Chassis look:

Nice looking model. The lifting height is a bit on the low side since you didn't use a double lift mechanism.

Have you considered putting the rear wheels the other way around? This way the attachment point of the wheels is closer to the rotation point. It will make them sag less.

Yes, lifting mechanism is simple. I tried to put the wheels the other way, but I figured it out late and the bodywork was already pretty wide for this option, my bad.
Big thanks for your remark! :)

Very nice design, but you should add some side mirrors

Your wheels are very, very flimsy. That's because you are not using wheel hubs.

Also if I'm not mistaken, the pneumatic cylinders don't reach their end positions. It feels like you should have used shorter cylinders.

Yup, I know, axles are not strong. I wanted to make chassis without hubs, so that was a mistake.
I didn't use small cylinders, because they werent strong enough (also I had only one of them).

I meant medium cylinders, not small.

But yes, medium cylinders haven't appeared in sets for many years.

Great job! Nice and tidy build.

Nice build :-)

Do you maybe have two more wheels of this size (the 68.8 x 24?) to fit on the front axle? Would surely look even better ;-)

Of course, they would fit perfectly, but it is hard to get them where I live. Maybe I should try using 62.4x20, but I have only two yet, I really want to get them soon. :)

Then maybe first try with the 68s as twin wheels in front and 62s rear steering wheels in the back?

I think 62s are pretty small for this option, but I’ll try it, probably it is really better. Thanks!

I just realized that I cant fit paired wheels in front, they will rub the body behind the first wheels. So, maybe I should rebuild front arc first.
