Lego Technic 2013 sets & info

[legolijntje]

Thanks for sharing the review and the pictures.

I really wonder why TLC did not choose for the other version of the telescopic boom that we saw on early pictures. It appears that in that version the second section of the boom has 7 gear racks 1x4 instead of 2x5 parallel in the final version. Eg, it seams that in the other version the 2nd and 3rd section could each extend 6-7 studs more... As well the looks of the retracted booms is much better, eg as mentioned the final versions seams a little mis folded, and leaves clearly a lot of unused space between the end of the 2nd section and bottom of the first second.

Very curious why TLC decided to do so.... Maybe the boom would become to heavy to lift when one first extended all sections?? And to avoid the internal clutch of the LAs to be addressed??

Well, I think TLC just wanted to give us an oppurtunity to modify this thing

But, I agree with you, the longer the extending boom, the better

Anybody have the pictures so we can compare the original variant with the final variant?

This is the best picture i could find from the top of the beam of version 1:

Actually, for comparison this link gives a better view on the 'previous' boom.

See of course the 42009 photo.....

And even the double 1x11 panel grey is a much better fit... Even wonder why this reconsidered. Maybe because the crane turret did not turn smooth over the surface of the 1x11 panel?

The grey panel would colide with 20 tooth gear...

I intend to agree if there was just one chassis version. But it seams that there are 2 versions of the chassis as well. The final version can not hold double 1x11 panels....

Hi all

I haven't kept much track of the Technic forum lately (mostly into LOTR...)

1- What functionalities do the new crane has that the 8421 doesn't? Does the crane base rotate via a mechanism? So far it just looks like a longer 8421 with 2 more wheels and LAs instead of pneumatics...

2- When will the exclusive blue variant of the 9398 4x4 crawler be available?

There really aren't any new functions to the new crane as opposed to 8421, but they are implemented differently. Far more is motorized. For example, on 8421 only boom telescope and cable drum were motorized. Boom lift was pneumatic. Steering and outriggers were geared. Slew was manual. On the new crane all of the following functions are motorized: boom telescope, cable drum, outrigger deploy, outrigger lift, boom lift. Steering is still geared and slew is still manual. In both cases a single axle drives the engine. So the new model is bigger and uses newer parts but does not add any new features that didn't exist before.

I think the dark blue 9398 car comes out August 1.

May be rotating superstructure was made non-motorized to prvent damage if someone want to rotate it by hand, cause worm gear (only way to rotate so heavy construction) is a one way gear.

There appears to be one other difference, in 8421 the cable drum was linked to the boom extention so that is would wind/unwind as the boom retracts/extends. The new one does not appear to do that.

So, with the motor in the superstructure, I wonder what happens once the stabilizers have hit their limits? Does the superstructure start to slew, or is the superstructure heavy enough that the clutch gear in the chassis prevent this from happening?

Sounds like a hidden feature. Slewing of the superstructure is motorized after all!

[EyesOnly]

If so then motorizing the slew separately shouldn't be too hard. Just one more clutch so to spare the gear train for the stabilizers.

[gmshades]

If anything, I would just want a manual slew like in 8460. Lego did it right by not motorizing it because kids will want to turn it. by grabbing on.

[MrNumbskull13]

ALERT! Noob question incoming: What does this 'slewing' mean?

[Cwetqo]

Turning the upper structure.

[designer-han]

Having the boom extraction and cable drum controlled at the same time is quite easy IMO. Just ad an additional lever in the gearbox.

According to this picture the functions are separated (bottom gear and top gear box).

Maybe quite easy, but don't forget that every lever needs a separate axel, otherwise functions can't switch indepenently

[Balrog]

Maybe quite easy, but don't forget that every lever needs a separate axel, otherwise functions can't switch indepenently

But since both functions need the lever to be set in the same direction, there is no need for separate axles on the lever. Only for switching in the other direction, because if you only want to operate the outriggers, boom extension would work as well, which is bad. Only in case of wanted boom extension it wouldn't make any difference if power is transferred to the outriggers as well. So indeed two different mountpoints for the levers would be needed.

But looking at how the axle for the lever is mounted, it shouldn't be too hard to modify it, so two levers could be mounted with axle pins.

I'm not sure the L motor will be happy if you operate 2 functions at the same time.

[Balrog]

Well, one would have to try ;)

[Anio]

Well, I am not home for a couple of weeks. I can not try.

However, I higly doubt the vertical move of the outriggers and the telescoping will work if another feature is operated. Indeed, these functions are already very slow.

Lifting the arm requires a lot of power too.

The hook does not need much power, but it has a worm gear in the mechanism. This part wastes some power.

Only one function can be operated at the same time. And I REALLY think that it is a brilliant idea. That way, each feature works better, and operating the model is easier.

I mean, 8258 and 9397 work well, but it is a bit more difficult to operate these sets.

[rener]

I'm not sure the L motor will be happy if you operate 2 functions at the same time.

I'm curious, maybe you could try it since you own the set! As it's either extending the boom + unwinding the cable, or retracting the boom + winding up the cable, I guess the L-motor should be able to handle this.

EDIT: missed your last post, seems that there are some good reasons to keep the functions separate. But the possibility of moving boom and cable at the same time (or not) was IMO one of the most interesting features of 8421 (and 8053, for that matter).

On 8053, these 2 functions were totally desynchronised ! :-S

I guess we will have to wait for some clever modders that enhance 42009 with this functionality. And hopefully they provide instructions as well ;)
