Ngoc Nguyen Posted March 7, 2019 Posted March 7, 2019 As I see it, the sets that use Unimog tyres or Class tyres are modeled after vehicles that in real life has wheels bigger than a human's height. Volvo Loader, Class Xerion, RTC all have wheels about 1.8 meters in diameter. I've been waiting for an official reach stacker with Unimog tyres and maybe XL LAs. Do real life reach stackers have wheels that big? Quote

jorgeopesi Posted March 7, 2019 Posted March 7, 2019 That reach stacker with unimog wheels would be too big... Quote

1gor Posted March 7, 2019 Posted March 7, 2019 1 hour ago, jorgeopesi said: That reach stacker with unimog wheels would be too big... It would be in scale with RTC (every day I pass one twice) and just for info it has tires with 1.85m in diameter like most if RTC. @Ngoc Nguyen Xerion has 2.15m tires... so RTC, Xerion and Anthem are roughly the same scale. Quote
jorgeopesi Posted March 7, 2019 Posted March 7, 2019 I think would be around 70 studs long, not too long for a set but I think a little long for a only two axles and plastic chassi set. Quote
1gor Posted March 7, 2019 Posted March 7, 2019 Perhaps some advance technique using frames could do the trick? Quote
zoo Posted March 7, 2019 Posted March 7, 2019 53 minutes ago, I_Igor said: ...so RTC, Xerion and Anthem are roughly the same scale. Are you refering to the Mack Anthem? I've been thinking about how it compares in scale to the Xerion. Is there a thread or website somewhere that lists licensed sets and their relative scale to the real life counterpart? If not, there should be. I'm aware of that it depends on what you measure. Overall Length, width and hight or Wheel size etc, but it should still be possible to get a rough estimation. Quote
AVCampos Posted March 7, 2019 Posted March 7, 2019 The easiest way to evaluate scale is compare the cockpit areas and imagine a human sitting there. Quote
1gor Posted March 7, 2019 Posted March 7, 2019 IMHO best way is to compare tires; CLAAS Xerion has 710/85R42 tires (2.15m) and 2150/107 gives some 1:20 Scale and Mack Anthem has some 1016 mm tires and represented with 49.5 tires is roughly 1:20 scale...RTC has 94.3 tires and real one has about 1850mm and here 1850/94.3~~20 (19.7), so it can also fit 1:20 scale...

Interesting. Thanks for the clarification! Do you happen to know the wheel size of the real MB Arocs? Quote

My RTC substructure is 75 studs long and won't bend even with 3 kg placed dead centre. A smart use of 7x5 frames, dogbones and diagonal reinforcements does the trick.

suffocation Posted March 7, 2019 Posted March 7, 2019 L motors are also great for adding rigidity. Quote

Bartybum Posted March 7, 2019 Posted March 7, 2019 Doing a Reach Stacker with the same wheel-to-body size ratio as that in the picture AND Claas/Unimog size tyres would be so pointless. Too big definitely is a thing, no matter what anyone says. A Reach stacker doesn’t warrant a model that enormous, especially since there aren’t enough functions. Most of the model would be empty structure. Quote

Sorry, I stand corrected. Going by tyre-to-body dimensions it would be similar to 42070's length, so it actually could very well make a fine model! Edited March 8, 2019 by Bartybum Quote
Ngoc Nguyen Posted March 8, 2019 Posted March 8, 2019 If a reach stacker has Unimog tyres, the arm would be as thin as the 42082 RTC arm. So I don't think the gearbox will be at the other end of the arm like the way 42009 B is designed. The battery box may still be at the end of the arm, but the motor and the gearbox will be in the base. Quote
Ivan_M Posted March 8, 2019 Posted March 8, 2019 Guys are you aware of @Lipko telehandler, right? https://rebrickable.com/mocs/MOC-6302/Lipko/telehandler/#comments perfectly possible to build it with unimog tires. Just don't wait for the one from lego, build this beatuy Quote
