I am planning on making the outiggers like in the mobile crane MK 2 (42009).

instead of adding an extra function to the gearbox im having the motors axle driving the pnumatic pump however it can still use the gearbox, this gives an extra function for the second stage of the outriggers.

gearbox.png

Lime = 12 Tooth Gears (for outrigger gear racks)

Light Grey = 16 Tooth Mesh Gear

Dark Grey = 16 Tooth Idler Gear

Red = Selection Clutches.

Black = Axles

The top output of clutch A is meshed with that lime gear and it connects to the other lime gear using two 8 tooth gears, because the lime gears cannot be offset and also must rotate in opposite directions and at the same speed./

The bottom output of clutch B has a gear on top of it which has been removed for clarity, this is the shaft that runs directly above the L motor.

As soon as I can get more new cylinders I'll make the outriggers extend and raise/lower pneumatically.

That is a good idea for space saving however I think it will be a bad idea using pneumatics for the outriggers as they will need to be synchronized and you cant really do that because of differing air pressures in each cylender. You can more accuratley control LA's and are probably stronger

Great news from Toronto! Bumped into one at lego store yesterday and bought it right away. Shopkeeper told me they just received it yesterday, limited to 1 per family and 1 per lego VIP.

I got one from Lego store in Liverpool today. Wasn't expecting it before 1st of August, but since they had it, I just couldn't resist it. Got the crawler crane too :)

I have disassembled my copy and I could not resist using new pneumatics in something. I tried to make an alternate model for this set, but I ended with this:

Actros clamshell parts put side to side look like ditch cleaning bucket, so I decided to make a wheeled excavator. Unfortunately, it will be not finished.

The arm works quite well, except the centering of the bucket (pneumatic tubes collide with bucket links). The superstructure can be rotated by using warning light on the top of the cab. Front wheels can be steered by that bevel gesr under battery box. The blade and stabilizers are missing and I have no idea how to make them working with parts that are left.

Whole excavator has got some major problems with stability, and that is the main reason why I will not continue building it. Also, I am used to have smooth shapes in my models, and all those holes and gaps look weird for me.

Why do they need to be synchronised? They are not in real life. The truck I saw at work had individual control valves next to each outrigger so they had to be operated separately and one at a time, which is required when not on perfectly level ground. And besides, in practice the pneumatics will be stronger.

Synchronized outriggers for a crane truck like this (or pretty much any crane truck I know of, at least) is not realistic at all.. Ideally one would have individual controls for each side, both for extending/retracting, as well as deploying of the outrigger pads.

Often you see these kind of trucks working on one side only,so it only needs to fully extend its outriggers on that side. Typically when working on the side of a road etc..

Arocs and crawler crane are on the shelf at TRU in Vancouver, Canada. $269, and $179 respectively....... Got shoulder surgery scheduled in the winter, so will likely get them then-its a long recovery, apparently......

And because I couldn't wait till Christmas :grin:

Allap what's the price at Argos?

Bytheway I've got the crawler crane on Amazon UK for £85....how much is the official price?

In Argos (which is usually the official price), 42043 is £170, Crawler crane is £110 and fire plane is £45, so £85 for the crane sounds great.

That's great news. Argos website is usually out of date anyway. I find it bizarre though, that its in the shops before the release date.

Note to self: Take a walk to the shops.

Enjoy it.

Thank you both for the heads up. It is on 3 for 2 until tomorrow aswell!

On the Argos website it doesn't list the new sets, also they say the 3X2 it's valid only if purchased online.......but they do have them in the shops, not sure what to do! i'm tempted! Or I should wait till saturday for the official release!

The 3 for price of 2 is available in the actual stores until close of Tuesday. Wouldn't have known they were available early without the other posters, so thank you. I picked up 3 today... seemed a bargain and hopefully a few parts for any MOCs that come up in the near future.

The difficulty is finding a store with that many, when you can't search online. Need to go instore and look at stock levels at customer services who were really really helpful.

Thanks for the info! I'll pop in tomorrow in many of them nearby and see if they have them! hopefully yes! Cheers mate!

I went around about 15 or so stores in the north east and could only ever find a total of 2 stores that had one in stock and as such decided to give up on the idea of the 3 for 2 and just went to the Lego Shop instead.

Anything like this but with inverted colour? But without the dump bed :wink:

Yes! Great minds think alike :wink:

Beautiful. BTW does anyone know why TLG decided to use DBG pulley wheels for the rims instead of LBG ones? It makes no sense to me....
