8443 Pneumatic Log Loader studless

[M_longer]

Another model built for LUGPol's contest

I have made few purely mechanic version of it when I was a kid, but how it could look in studless?

The original set had very cool mechanics, with steered wheels and articulated chassis:

It worked smoothly, my model does not work as good as the original (thanks to bigger wheels and different dimensions) but it is quite good.

Pneumatic circuits are simple, but arm movement is more than interesting. Let's see what Blakbird wrote about it:

The boom can be lifted pneumatically. An actuator pushes to pivot the boom up and retracts to pull it down. Because the actuator rod end is not mounted to the boom itself but to a link attached to the jib, a 2 stage motion results. As the actuator extends, the jib first rotates outward because it requires less force. Once it bottoms out, the entire boom lifts. This motion is repeated in reverse on retraction. This system results in a system which mimics the motion of a system with two independent actuation circuits, but achieves it with a single actuator. Genius.

Here is how it works:

And if anybody would like to build this thingy, I have made instructions (styled as old ones):

Very great Studless version of it and gives me the same old school feeling

Nice homage to the original! Lugpol has lots of competitions like this, I should follow your comunity more often, these are really fun.

Its interesting how the new'ish parts and panels make this almost 20 year old design look modern and fresh.

To be honest, I'd like to build it totally different, but functions and overall dimensions had to be be as close as possible to the original set :)

Cool. Looks much like the original minus the studs.

Did you win the LUGPol contest?

The contest ended at midnight, now we will have to wait for voting topics :)

Looks great, even though I never had the original set.

Me too :D

I built mine after reading Blakbirds Technicopedia and reworking LDraw file.

if not for the Technicopedia.... just like most of us who saw the page ...

I still think the best one is the ship if you know what I mean :)
