I have checked my build and first I thought it is not touching but now I check the pickture I see yellow on the gears :(

would it be possible to replace this 24+8 combination by 20+12 to avoid this part collision? would the down-gearing sufficiant for the LA-drivetrain?

Hi!

I just finished the set a couple of days ago. To solve this problem I just changed the yellow piece to a black one. The black one is a bit thinner, so no worries.

really?? no parts collision between the 24th gear and the black connector? can't believe that there is such a difference only by color...

Maybe because black one has a cutout? Can you post a image?

Very epic, would love to have it on my shelf.

Hi!

Tomorrow I will try to post a photo.

Yes black one is a bit thinner compared to the yellow one...

Hi guys!

Unfortunately my mobile phone's camera isn't good enough for a macro photos. I try to ask for a better camera tomorrow.

Just finished this ultimate mobile crane:

Juergen: kudos to you for this awesome model :thumbup: :thumbup: - IMHO it's more a MOC than a MOD... and it is very well designed, you have admirable building and designing skills - i had really much fun when building it - the resulting model works like a charm and performs very well - the XL has no problems to drive this heavy model. Great playability (in contrary to the original crane which has mediocre playability). Cause of the plethora of additional PF-stuff it is a very expensive MOD but IMHO it is worth every cent. Strong recommendation for all owners of the 42009

Nevertheless i have applied some small MODs to this MOD:

1. (the most prominent one): i have replaced RC-ing of the outriggers by two PF-switches:

I did this mostly to save one receiver and one sender (which are more important for other cool MOCs ;-). And IMHO this fits better the real live usage, because normally the crane driver operates the outriggers with a cable remote control...you think this is a contradiction? no, IMO it isn't: The lego RC is the replacement for the driver in the crane cabins whereas the lego PF-switches simulates the outrigger cable remote control of the real machine. Anyway: the two switches are very easy to integrate - just one important remark: on the pic above you see that the switches are in a row with the receiver (in the backward direction); this is important because otherwise (if they would be in a row in the frontward direction) they would be one stud longer backward than the receiver and would therefore prevent the crane from endless slewing! for this see also 4. below

2. slightly longer engine bay so the receiver, the switches and the cables are better "hidden":

3. fix for the part-collision problem described some postings above:

In the original design this yellow pin connector collides with the DBG 24th gear which drives the LAs. IMHO this is an illegal design. my fix above eliminates the problem - at least there is no parts collision anymore (but i assume the design would still be judged illegal by lego) - aynway: now it works.

4. i have mounted the crane one stud backward - this can be done very easily:

This ensures that the crane can not touch the cables at the receiver and the switches of the truck when slewing more >= 180 degree. This is already useful with the original 2 receiver design of the truck but with my switches replacement it is essential because the cables of the switches needs slightly more space... anyway: it has no costs, it is easy and it has no disadvantages.

5. adding some more support for the heavy crane and its mounting plate:

6. some small fixes:

- better bracing og the orange L-motor for boom extraction:

7. fixing a bug:

That's it. All of these MODs a very small and light. But nevertheless they slightly improve an already excellent model.

(all pics can be found in my bricksafe folder: http://bricksafe.com... RC mobile crae)

Conclusion: Thank you Juergen for this awesome MOD which hauls up the crane to another and much higher level. And also thank you for the perfect instructions which gives you a very enjoyable building experience.

I'm nearly finished with the Ultimate 42009. I solved the LA-cam (boom) lift problem by using a #5 axle through the cams and boom lift bracket hole. Then placing the LA's pin hole on the axle. A second #5 was run through the LA and cam axle hole to stabilize the assembly. I realized that the cams now serve no purpose and were replaced by two 60483 beams. I know that one picture would indeed be worth all of these words but I lack the computer skills at this time, to post it.

Just wondering if anyone had built this incorporating an SBrick?

I ask as the present controller arrangement makes the finished build almost unuseable to me.

Yes, a useable profile for the 42009 ultimate is still missing :(. With the profile designer it's at least possible to create one.

Thank you. I had a feeling there might be. I think I'll get one and see what it can do.

Thanks again.

What I don't like about 42009 is that, unlike the Mk1, additional string isn't paid out as the boom extends to keep the position of the hook the same relative to the end of the boom. Has the ultimate 42009 dealt with this?

I have not build the ultimate version yet but I think this should be possible.

I modified my 42009 to have to Changeover Catch following Bimnomercy idea

(http://www.techlug.fr/Forum/post147049.html#p147049) to do it :-)

Blindingly obvious now I've seen it. Still requires you to do both, but it's a way round :)

The ultimate doesn't Need this festure because you can simultaneously operate winch and boom Extension with both hands in the IR senders. Both functions have its own motor!

Hi

Can 2 of the M-motors be replaced with L-motors?

I'm asking because I only have 3 M-motors and plenty of L-motors so if 2 of the M-motors could be replaced with L-motors I don't have to go shopping.

Edited June 18, 20159 yr by nep

Yes you could... but L Motors are bigger and need more space... So you have to check if there is enough room for this motors... The speed is almost same, L Motors are more powerful... So the only problem is space...

Max...

Thank you for the quick answer.

I was wondering if anybody has tried it and knew where there there is space and where there isn't

This is my version of Jurgens U42009. I believe that I've incorporated nearly all of the suggestions from the forum and added a few of my own. These include filling in some of the pannel gaps behind the cab and on the sides of the crane. The biggest change is the addition of the Christophe boom. The base was modified to allow the boom to lift to about to about 85 or so degrees. With the addition of the second counter weight, an interference problem developed when the crane was rotated 180 degrees. To solve this I shortened the engine and moved the IR receivers forward.

Just finishe motorizing mine.

AWESOME!!!!!

Thank you for the gear clash mod I was just building this part when I found your post so didn't have much to strip to employ your fix.

BTW the Yellow part is identical in size regardless of colour but I'm sure most know that.

Could I be the oldest reborn Logoist? at 58

Just bought my 42009 brand new on ebay for £169 and got a £20 refund because the seller didn't protect the box for shipping.

I did the full RC 42042 by Catweazel last week, brilliant! six motors.

Your gear clash fix

Your reinforcement "bug fix" easy without any stripping

Another bug that I've just encountered myself is the four unnecessary pins (two blue bottom of picture and blue black top of picture) here with turntable removed for the view.

As no beams are installed there what is the point of this arrangement? when they could all be black pins finishing flush.

I appreciate the gaps are left so you can get your finger tips in for removal of the outer parts

Surely neater unless I've misunderstood ?

I installed the first Sbrick today and made some modification to mount it. I also connected the LED's to the drive motor so they only come on when on the move

Edited January 22, 20169 yr by Techno

I got back into Technics after not having any since I was a kid, 25 years ago. I bought the 42009 from BrickLink over the holidays and completed it last week. I would love to remake it into the Ultimate 42009 but the cost to do so is very expensive being in Canada and having no spare parts on hand. It is definately on my list to do though. I picked up the 42043 set this week and am starting it this weekend.
