2H 2015 Technic sets in Nuremberg

Nuremberg Toy Fair 2015 is already running and yesterday it was open exclusively to the the press.

Hence we started to see the first images in the afternoon and there was a bunch of news about LEGO future products. Although and since everyone here is all about Technic, let's focus on the LEGO Technic sets news.

The first image we saw was from the 42042 Crawler Crane.

From this we clearly see it confirms a standard blue crawler crane with a long boom. In the photo presented it has applied the boom extension section, which is applied with some pins with stop bush. But this is basically what we already knew.
The news are on the details that we can see now from this detailed image. There is a four functions switch box, which looking into the details we can narrow down to be:
  • Boom raising/lowering (via cable)
  • Grabber claw up/down (via cable)
  • Superstructure rotation
  • Drive (forward/reverse)
These are the motorized functions which is a nice surprise, has most of us were probably expecting no more than two of them. The relative large scale of the model, has definitely contributed to make this possible.

There is also a manual function which allows to open/close the claws  in the grabber, from a knob in its upper side.

Biggest surprise here was to see the drive gets motorized first, and second it doesn't steer (see the axle in the front connecting the left and right track drive wheels. Although this is understandable if we realize this is not an RC model which make the steering function a bit less important (the presence of motorized drive is aleady a bonus). There was only one fourth function available and this cranes are necessarily slow, so it is natural the choice was made for the drive and to sacrifice steering.
There is a certain level of greebling in the superstructure which is also a nice aspect.

Some complain about the lack of realism in the boom, but is looks perfectly aligned to what we can expect from an official LEGO Technic model. Truss has never been easy to build out of Technic beams.

Overall this looks to be a very nice model and a must have!

Then in the evening we saw the first video for the LEGO Technic booth which made everyone to explode in joy!

This as been a valuable resource to take some quality snapshots where we can see all kinds of details.

Let me start with the first known image of 42040 Fire Plane. The details are not much visible from such small section in this video still, but together with the descriptions we have seen earlier, already enough to see the smaller set in the 2H looks to be very promising also

This is a single propeller seaplane which main noticeable fact in this image is that we can find several of the new trapezoid panels (Design ID: 18945) in white color. Further images should reveal also some additional details.

But that was not one of the stars in this video. It was the crawler crane which we already talked about and obviously  the 42043 Mercedes-Benz Arocs 3245. Fortunately the video seems to have been done by someone with interest in the subject because it focus many of the main interest topics and questions about this model.

Believe it or not, one of the first things that caught my attention in these images was the presence of truck shims under the tipper. Those yellow parts that might be removable to put behind the rear axles, which btw are both double wheeled. A nice touch of detail indeed!

Then we have a lot more to talk about and I'll try to be synthetic, although I'm not sure where I should start...
  • In the boxes behind we both the crane and the Arocs have one PF L-motor and one battery box.
    The Arocs also includes 4 pneumatic cylinders (2x 2/11, 1x 1/11, 1x 1/5) with at least 2 new designs (2/11, 1/11). Not sure about the smaller one but it is like the same as before.
    There is also 4 pneumatic valves (no, not yet the PF version...) and one pneumatic pump (likely the same 6L version we got with 8110 Unimog and 42008 Service Truck), as seen in the box front view (image below).
  • It is obvious there is a new type of gear rack in DBG and one sliding sleeve where it runs through.
    We get one in red at the crane extensible boom and likely (although not clearly visible) another two for the outriggers deployment (eventually also in DBG).
  • The outriggers vertical adjustment is manual through worm gears as already expected.
  • The tipper is quite large and deep and it is a motorized function. From the video we can be sure it uses at least one linear actuator (presumably the large version), although this is not seen directly.
  • There is a clam-shell bucket in the tip of the crane which looks a bit smaller to my eyes then in the preliminary images. It might be a matter of perspective.  
  • The crane has 3 sections and it uses the 3 larger cylinders. The smaller one goes inside the clam-shell bucket to make it open and close.
    With 4 cylinders deployed in the crane arm the is obviously many pneumatic tubes around.
    There is also several of the recent pneumatic hose connectors with axle connectors (DBG) to join different pneumatic hose sections.
As for the motorized functions we see two levers, one at each side of the truck. Hence we should be able to have up to two of them working simultaneously.
On the right side we have the tipper and the pneumatic pump for pneumatic functions via the respective valves control (manual). And on the left it looks we have the outriggers deployment and crane rotation.

    But the details about new pneumatic elements are not over. See the images below.

    Both type of the large cylinders are in fact 11L as you can easily measure using reference elements around these. They should extend about 5 to 6L which makes them 16-17L long when fully extended. :D
    And both have metallic rods. We are still to see how these perform or better said how the single motorized small pump can effectively supply these with enough air at convenient pace.
    The 1/11L cylinder looks specially interesting  to my eyes, obviously depending on the maximum stroke it can supply and the seals effectiveness to prevent air leaks. For specific applications and designs it looks really interesting and useful. Both of them in fact... We can already anticipate other amazing official pneumatic Technic models and MOCs off-course.

    From the image in the left we can also see the connection point in the base of the 2-wide cylinder got a new design and it has now 1L with. This makes it much easier to use the pneumatic cylinder with the Technic odd sized based building system.

    Unfortunately we wont get an updated design of the 2/7 old cylinders with this set.

    On the image at the right we can also clearly see the tipper uses curved 11x3 panels in the bottom, which is also a nice technique variation.

    As for the cabin design I'd say it really got the essence of the MB Arocs look, and the printed shield element with the Mercedes logo is a really nice detail.
    The whole model is not much dependent on stickers and those existing are quite small, which is also a good thing.

    Finally about this image, we can clearly see who is the designer of this magnificent model. Some were expecting it to be Uwe Wabra as he uses to build the large trucks, Markus Kossman got the job this time.

    From these images we get the confirmation about one of the most speculated topics around this Arocs model - "Will it have suspension or not?". Yes, definitely it has! Both of the front axles have suspension has the big distance between the wheels and the fenders made us to suspect from an early leaked image.
    The steering looks to be proportional and both alxes are connected through a linkage bar.
    It is also not totally clear but giving that we can see some gearing on an axle connected to one of the beacons, it looks reasonable to assume the steering control is done via HoG from one of these beacons, if not booth.

    As for the rear axles with double wheels and since the space available is quite smaller, it looks we get some kind of pendular boogie, but there are not much details we can see from the footage available so far.

    From this last snapshot of the video we can see the cabin can tilt, to reveal the L4 engine underneath.

    Now that we have most of the 2H sets mysteries solved it rests to wait for them in the shelves and make our wishes for 2016...
    I want a decent Forklift flagship as we never got one and also we don't see any Technic forklift for too long. It is also a great option to make an interesting B-model variant with some other kind of lift.  

    If I remember anything else worth to mention, I'll keep adding to this post.

    I noticed on the crane that the two Levers on the back that operate the 4 functions each have two modes that operate both directions of the function (example being lever forward, tracks move forward, lever back, track move backward). Also, on the truck, I see 4 LBG springs on the front of the first dual axle and back of the last axle. In between I see a mini turntable, so it appears to be pendular suspension with shock absorbers. Plus, is the vertical tail wing on the fire plane a new piece?

    Ondra said...

    Engine will be L6 for sure, because arocs 3245 mean that it is 32 tons truck with 450 horsepower engine.450 HP engine in arocs is 6 valve.

    If this engine will be only L4 there no point to put it also under crane.

    TechnicBRICKs said...


    Actually I've seen the same springs later in another video, so that's definitely a pendular bogie with shock absorbers.


    Maybe I've overlooked this L4/L6 thing, but there is no way to be sure about this from the images we have seen.
    Designers tend to simplify sometimes, specially if there is space shortage. :P

    Ondra said...

    But this will be fail to put only L4 when all arocs have L6, I think this will not be approved by Mercedes.

    Same scenario will be probably with dual wheels.

    Ondra said...

    In this video that you posted on Facebook is probably visible crankshaft of another pair of valves under the cabin.

    Arocs is going to be the best set of all time and the new parts it comes with will make future sets better also. Markus you legend! I can't buy just one arocs, I'll have to buy more, and also order many extra parts from Lego. it has everything you could want from a set, mechanical authenticity, complexity and it is sure to be a fun build with all the different kinds of structures like suspension, gearboxes, pneumatics and more. some questions remain about the Arocs.

    So will the stroke of the new large cylinder be double that of the previous one (7 instead of 3.5) or do you think it will be slightly less?

    Do you think both rear axles will be connected to the engine or only one?

    Is the tipping bed powered by gear rack or LA?

    How much freedom of movement does the axles have, as much as the real live axles or just straight up and down?

    Will the compressor cope with the larger cylinders? Will two motor pumps be included?

    What changes might we expect to see between now and it final release?

    Trying to answer at least some of your questions.

    "So will the stroke of the new large cylinder be double that of the previous one (7 instead of 3.5) or do you think it will be slightly less?"

    I think the stroke will be somewhere between 5 and 6. More likely 5.5.

    "Do you think both rear axles will be connected to the engine or only one?"

    From the second video I shared on FB, I suspect about something new in the middle of the two rear axles. Don't know exactly what but it looks some kind of diff.
    Guess both axles will be connected to the engine.

    "Is the tipping bed powered by gear rack or LA?"

    I think it is a large LA, but can't be sure.

    "How much freedom of movement does the axles have, as much as the real live axles or just straight up and down?"

    From shock absorbers connections guess the live axles can also move sideways.

    "Will the compressor cope with the larger cylinders? Will two motor pumps be included?"

    This definitely remains to be answered. :P

    "What changes might we expect to see between now and it final release?"

    None! IMHO. :)

    TechnicBRICKs said...

    As always, no one ever remembers that the most important photo is from the bottom view!... :P :)

    Moune said...

    You missed the new turntable on the truck

    Allanp said...

    I saw the new turntable, looks about the same size 56t but stronger and with less friction. The thing between the two rear axles is a 28t turntable to allow the axles to be connected whilst being able to pivot independently of each other.

    TechnicBRICKs said...

    I didn't notice a new turntable, but if you saw it, I might be overlooking something. :)

    As for the rear axle group, indeed it seems the the 28t turntable there, there I think it is much less likely to have both axles driving the engine. :P

    Allanp said...

    Watch this video and pause at 0:39 to see the new turntable.

    When the video revolves round the Arocs you can see a diff in the rear axle and a drive shaft going to the front rear axle. There must be a drive shaft running through the 28t turn table so it seems almost obvious to add another differential in the front rear axle. No real need for a third diff between the axles.

    TechnicBRICKs said...

    Yes, it looks there is something new about this turntable. A new version a redesign, something!
    Wonder what they have improved in it? :P

    As for the rear axles, honestly a can't see much about them, and still have some question marks about the surroundings of the inter axle turntable...
    If there is a diff in the rear axle and one shaft goes through the turntable, the could be a symmetrical setup on the other side, but that will be quite weird... :P :)

    Unknown said...

    ...just around 2:42 you can see sicker on the back righ angle of the cabin (just before the crane) it says "6" + some small unreadable text. It could mean that it is 6L engine...:)

    Unknown said...

    ...or it could mean that it follows Euro 6 norm...XD

    Unknown said...

    It'l6 not l4 at eurobrick we get more and it's l6
