This is my first motorised pneumatic set.

It uses an automatic compressor.

To control valves i used a multiplexor system, that allows me to open or close 2 valves with just one motor.

The lying cylinder rotates the crane arm.

8868 on steroids!
You have implemented nice functions.
I guess you couldn't make it a little bit shorter, to avoid weak point in the middle of the chassis?
Rotating claw is nice touch!
Your video is good, too.

I like the rotating claw feature, very cool.

I'm not 100% taken on the colour scheme of the cab, maybe it is just the shape that looks a little odd, however feature wise, great.

Very nice work with this, has some nice features. I think it would look a bit better if it was shorter but not much you can do about that without rebuilding it.

Yeah, that's exactly what I thought !

Dark bluish gray is not my favorite, but the truck is great anyway.  :thumbup:

Looks really good.
I'm surprised to see you have use a small piston to build the compressor instead of a small pump ???
I like the valve design and would love to see some close ups if they are available.

It's not a pump. This cylinder is used to switch on/off the compressor!

Very nice truck. I see you don't have many pieces yet but you still managed to implement nice functions into the MOC. I don't like using pneumatics as the boom raising/lowering device because it causes it to drop along with it's cargo.

Keep up!

A cut off switch. Cool!
