jono rocky Posted February 2, 2015 Posted February 2, 2015 G,day everyone. I've decided to enter this competition with a Technic concrete truck. All I have at the moment is a piece of paper saying build a truck. The functions will be: Servo motor for steering L motor for drive L motor for mixing bowl M motor for either a small actuator or pneumatics for the raising and lowering of the chute. Now for the wish list. Rear suspension will hopefully be Hendrickson bolster spring, twin steer so it will be an 8x4, based on the Kenworth K200 and model team size for the challenge to cram it all in there. All going well the bowl will work as to the real thing. As a guess proportion wise the truck will be 45 studs long, 17 wide and from 19 to 30 high with the bowl. Which should make the bowl 27 to 30 studs long and 17 wide. I used some beams connected together looking at a pic of the eight wheeler concrete truck I used to drive with Boral. It had a bowl capacity of 8.5 t but I think that might crush this little truck. Will make 2-3 removable chute extensions and possibly a fake 3 cylinder motor, opening doors and tilting cab. Its all in my head as I ramble on so better stop that and start doing before the functions get bigger then the truck. Quote
aminnich Posted February 2, 2015 Posted February 2, 2015 Looking forward to some WIP pictures! Is the truck going to be model team? Quote
jono rocky Posted February 2, 2015 Author Posted February 2, 2015 Unfortunately no simply because I don't have that type of Lego so it will be just Technic panels and beams. Quote
aminnich Posted February 2, 2015 Posted February 2, 2015 Do you have an idea of how you are going to make the mixer? Just beams or are you going to make it more complex? Quote
jono rocky Posted February 2, 2015 Author Posted February 2, 2015 I've created one half of the outside of the bowl with beams and currently figuring out the spiral fins on the inside and how to fill in the gaps.Will have a pics ready tomorrow of my progress so far. The bowl is 15 x 27 studs and the rear opening is 9 studs wide. Has 8 sections to make it round. Quote
aminnich Posted February 2, 2015 Posted February 2, 2015 cant wait, btw if you have not noticed. I like cement trucks Quote
Lakop Posted February 2, 2015 Posted February 2, 2015 You've got your work cut out to make this in time. A cement truck is a challenging one. Look forward to it. H Quote
jono rocky Posted February 3, 2015 Author Posted February 3, 2015 Here is my first update or should I say last nights attempt. This shows 2 chute extensions, the front nose of the cab and front half of the chassis. Here is my moc of the bowl and the 2 chutes together and then just a couple of extra views of the bowl. Quote
aminnich Posted February 3, 2015 Posted February 3, 2015 I really like that! it is a great start!!!! Quote
Ode Posted February 3, 2015 Posted February 3, 2015 Great idea, and nice work so far. You might want to take a look at this one for some ideas. Quote
jono rocky Posted February 3, 2015 Author Posted February 3, 2015 Great build on the truck, I like the green pickup truck on your page. :thumbup: Have made the hendricson bolster spring suspension with drive to both axles and completed the motor and drive on the a frame mount for the bowl, will have more pics soon.

jono rocky Posted February 4, 2015 Author Posted February 4, 2015 This pic shows possible IR receivers or sbrick location. This shows the hendrickson bolster spring setup. The flexible rubber axle connector acts as the cushion for the travel. Bowl connected and suspension travel. Quote
TheItalianBrick Posted February 4, 2015 Posted February 4, 2015 CUte but there is a big problem: it's out of scale! Those wheels are too small in relation with the mixer...or the mixer it's too big compared to the wheels....you chose! Nevertheless looks so nice and cute! clean aswell...so i like it! Quote
aminnich Posted February 4, 2015 Posted February 4, 2015 WOW, that looks great, especailly for the size, very compact, love it. You are out of scale, but that is not the biggest concern Quote
