42055 - Bucket Wheel Excavator
Ngoc Nguyen replied to Jim's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I assume that you intend to put your gearbox in the same place at the model's one. You can take a look at the picture below; there are only spaces for 3 yellow axles going down from the upper arm. Your gearbox has 6 different output axles. So I can't really imagine how you'll route all 6 of them down. -

Holy molly, that's a lot. How do you intend to pass all 6 axles down the superstructure? -

Why don't you make 4 and 5 control 2 tracks separately, like in 8043? -
I have some idea to put a gear indicator near the steering wheel. In the building instruction: - Step 137: Replace the 4L axle with a 8L axle or longer. - Step 159: Turn the orange connector with axle hole up. - Step 162: Replace the 12L axle with a 10L axle, or just don't push the 12L axle past the 12-tooth black bevel gear. Now the gear changing axle is extended on top of the steering wheel. Now the speedometers have to be compromised in some ways, which I haven't figured out yet. I'd like to see someone develop more from this.

Or maybe, the LA is made manual simply because there is only enough space for 3 axles going down, and driving the BWE, driving the belt, and rotating the turret are more important than moving the LAs. -

I'm reminded by the 42009, and the jerky movements of the outriggers. Even the L motor can't handle a bunch of gears in the 42009. This BWE may encounter a similar problem, even with the XL motor. Let's wait and see if Markus learns from the past. Probably because of that reason together with the prevention of all 3 functions being engaged at the same time. I mean, from the mechanical perspective, if all 3 functions are engaged at the same time the motor won't have enough torque, and thus maybe none function will be working. -

Background info for those who don't know: The BWE has 3 motorized function: - The upper switch: turn the superstructure, and only works when the middle switch goes up. - The lower switch: drive the BWE, and only works when middle switch goes down. - The middle switch: when it goes up, it rotates the bucket wheel + drives the conveyor belts + enables turning the superstructure + disables driving ; when it goes down, it disables turning the superstructure + enables driving. I have been wondering why Markus made the turning and driving depends on the bucket wheel switch, and I've just had an idea: maybe to prevent 3 functions engaged at the same time. -
Can anyone with the set describe how big the Porsche box is, comparing with the flagship box (Arocs box, Volvo box, Mobile Crane box...)?

For me, a set that makes me love rebuilding it has to meet the following criteria: - Do not take too long - Have some techniques that make me delighted - Not have some techniques that put me off - (Optional) The final result looks delightful Hence at the moment 42052 is the winner for me. Other sets that meet the above to me are 42042, 42043 minus the pneumatic crane, and 42009 B model. I'm not really into building the 42009 A model because its outrigger forces the 16L axles to bend, it doesn't work very smoothly, and it lacks realistic details. Other sets of mine include: 8043, 9398, 8070, 42030, 42025, 42040.

Why 8288 when you can have 42042 -

The 42009 doesn't have much lifting capacity, so I doubt it can help. I have one, and once tried to get it lift a keychain consisting of just two small keys. The winch struggled a lot. -

According to Sariel, the mine truck in this set is designed from scratch, not a copy of the yellow 42035. And it seems the white truck contains something the yellow one doesn't. -
I think both swapping axles and changing the catchover directions are being put in place deliberately by TLG, so that people can tinker with it and discover the right way, just like some people like to tinker with their cars. As the video points out, it just doesnt make any sense at all to use a catchover when a 2M liftarm can totally serve its place.
