Ah, my bad

[efferman]

i have the powerswitch servo optimized. now the full 90° range of the servo is used to get a proper neutral position of the switch

edit: short test of my sparewheel tirelift. what do you think, should i use an electrical or mechanical winch?

It looks like you are using a 12t to 24t (2:1 reduction) to rotate the switches (180 degrees of the servo results in 90 degrees at the switch). I have found that a 3:1 reduction seems to work quite well (either 12t to 36t, or 8t to 24t) (180 degrees of the servo results in 60 degrees.at the switch).

I like your method of attaching the spare wheel. The two stages with the assistance of gravity is a great idea. In real life it would be quite difficult to lift up a large wheel like that, so I'd like to see it motorized rather than manual.

[efferman]

i use a 12/48 (1to4 reduction) combination, this uses perfectly the full range of the servo.

[Zerobricks]

Use pneumatics, because they are rarely used anyway :)

[efferman]

hm no, this would be not realistic.

btw, i have tested the pulling performance with a 11kg boy and his buggy

[N-4K0]

Wow, pulling 11 kg must be a sensation for a vehicle made from Lego Technic

[Bob De Quatre]

Be carefull, the boy might take a liking to this mode of transportation

[efferman]

oh, he like it definetly, but next time i should better use an "bollerwagen" (a little flatbed trailer for pulling per hand) to get a better steering. the buggy was terrible in this point.

btw, the electrical winch is ready for use and a big black shock absorber is pushing the tire over the gravitypoint

[Someonenamedjon]

Wow! Very impressive on that huge haul!

[rm8]

Papi, what's going on?

Generation "Afol fathers" will be here soon.... 20 years later:)

[efferman]

you made my day

btw, a first sketch of the turntable, it is a revitalization of a old unfinished project and will be later fully integrated in the frame

[bricky300]

Thats looking great :)

Maybe you could post a picture showing the underside of the truck?

[efferman]

i hope the technical inspector doesnt hide too much

btw, a first sketch of the front outriggers. the cab i will mount when the frame with outriggers is finished

[timslegos]

That frame looks beastly! How many functions total will the truck have?

tim

[efferman]

hm, the plan says following

driving and steering, the tirelift, outriggers (not sure which ones), three or four section telescopic boom, lifting and rotating the boom, two winches and a simple towing system.

[Alasdair Ryan]

Have you made any attempts at the telescopic boom yet?

I could do with one for my truck....

[efferman]

not yet, first i will finish the undercarriage

[Alasdair Ryan]

A one stage stage boom is easy peasy,a two stage boom is a little harder.

While a three or a four stage boom is much more harder.

[efferman]

i have 27 studs in width for the boom. there should be something possible.

i think i have found the final outrigger design

[Saberwing40k]

wait, are you trying to tell us that the boom scales down to 27 studs wide? My question is how long is it. Depending on how much space you have, it could be quite difficult to implement a four section boom, as I've found out from personal experience.

Also, it's really hard to make a knuckle boom crane at this scale that has a telescopic section, as I've found out myself as well. I think you'd be lucky to get one extension out of it.

[efferman]

no, the full truck is 27 studs wide so i can make the boom wider before it look to fat in relation to the truck. the boom will be roundabout 45-50 studs long and to be exact, 3 section means 1 solid and two extensions. maximum reach is not my goal on this crane. i want simply could lift a 9398 to realize my idea for the final vid.

[efferman]

the front outriggers are finished, first in driving position

and fully engaged

Looks good, and solid

Btw, I'm wondering - does the term MOC stand for something, shortened, or is it just a "random" term?

It stands for My Own Creation
