[MOC/MOD] Self-loading Logging Truck (set 9397)

Recommended Posts

Back in 2012 set 9397 Logging Truck was released. It was a nice set and I bought it to motorize. But looking on the internet for real self-loading logging trucks I more and more started to want to make this set as a base for a more scale model look.

So I made the truck wider from 15 studs to 17 with is more in scale with that type of tire. Eventually I designed a complete new truck based on the set, but looking more like an original US Logging Truck and fully remote controlled.

It has just only taken me 4 years to complete the video... hahaha. Due to free time and not completely satisfied about the video material I never got to making a video. The video material was shot by a well known Dutch Technic master Mahj :grin:

On July 2012 We went to a nearby forest to find a good place for shooting the video material with a nice backdrop.

Yesterday I went to mahj to help me with getting to know the new video editing software Mahj already has good experience with. And here is the finished result.

Function:

2 M-motors for drive

M-motor for steering

M-motor for switching between two functions

M-motor for moving the second steering axle / moving the crane arm back / forward

M-motor for moving the outriggers / moving the boom up / down

M-motor for turning the crane

Micro motor for rotating the claw

Micro motor for opening en closing the claw

Because I wanted the crane to move freely I decided to place the control of the 2 micro motors in the crane it self, place the battery pack and receiver on the crane. This so the wires couldn't get entangled with the gears.

I have found a basic sketch of how all the gears, axles and motors are connected in the small chassis. I will make a LDD drawing of this and post this soon.

Very nicely done! I live in one of the primary logging areas of the United States and I see these types of trucks every day. Yours is immediately recognizable and very accurate.

So many well executed functions, and like Blakbird, I occasionally see these running around as well here in New England. Makes me sad I sold my copy...

It looks great and performs much better than the pneumatics on the 42043. I love how clean the crane arm looks, even with a couple of wires running along it. :thumbup:

Thank you all for the nice reactions. Good to hear you like it and that it pretty close to the originals (Thanks Bladbird and JGW3000).

As promised I have made a LDD file based on the old CAD-file I made in 2012. Looking at the photo's I have of the model, the CAD-model wasn't 100% OK. Making a LDD model of all the gear is no picknick. Took me a all day to make it.

If you want to see all the part up-close, I made a couple of screen-dumps of the different functions. See the https://www.flickr.com/photos/50191917@N06/albums/72157667182246325]Flickr album[/url]

@Ludo Visser, Yes. In the album there are also some pics from the Europe Model Show 2012.

@2LegoOrNot2Lego, The model was taken apart in 2013 (I think) after shooting the video material. Back then I didn't have that many PF parts and this one had almost all my M-motors.

I still have a lot of model on my shelves that I want to take apart, but I still have to shoot (Photo's and Video's) them. It is getting pretty crowded here :grin:

It's fantastic Barman! I like the use of the micromotors in the claw because it looks clean... :wub:

You say 4 years... Well, never late than never :laugh:

I love the way the trailer is deployed, its like a transformer. Great use of micro motors, I wish we had a modern equivalent.
