I actually changed the gear ratio from 24:8 to 20:12, since 24-teeth gear won’t fit in a small space. It works fine, though. Perhaps it’s because the steering wheel is too big.

It’s OK, there is a tiny space down there when the forklift works on a flat surface. That’s one reason, another reason is that it makes the chassis symmetric, something I preferred. Otherwise I have to use 2 M motors on both sides.

EDIT: Parts list & building instructions updated: HERE ________________ Greetings! Kevin again. I’ve got a new MOC to show you guys: a new version of my custom forklift. A year ago, I built my first decent MOC - a RC forklift, and shared my building instructions. That’s less than 9 months since I bought my first LEGO set (8043) in my life when I finished that forklift. It was a very premature creation and I planned to upgrade it long ago. Now this new version is done. So, what’s been upgraded? It’s been totally redesigned from the inside out. Now it has a better lifting performance, a better looking, and much easier to maneuver. Lift assembly is powered by 2 PF L motors, it can lift up to 0.9kg of weight. I used the same lift mechanism as the old version, because it provides a reasonable lift height, which linear actuators failed to do. The assembly is a bit thick so I used technic beams to replace the old technic bricks, and 8-teeth gears instead of the old 12-teeth gears. It is front-wheel drive and rear-wheel steering. In the old version I used the steering mechanism of Madoca's AWD SUV. It’s a great design but not so good for a forklift. I redesigned the driving & steering systems, now it steers more like a real one and has a much tighter turning radius. A short video demonstrating all major upgrades(1080p @ 60fps): Another clip showing the chassis and how motorized functions work(4K @ 30fps): 1 PF XL motor for propulsion, 2 PF L motors for lifting, 1 PF L motor for steering, 1 PF L motor for tilting. More photos: I was planning to make the steering wheel and levers functional, but there is not enough space down there, And making the levers’ movement authentic is quite complex, I have to give up that idea and made it manually controlled. At last, see more of my creations at Rebrickable & my YouTube Channel. I’m working on building instructions and hopefully it will be released in a few weeks. Stay tuned!

This is mine: I used to stack all my parts in those blue stacking drawers at this corner. Since I just got a new shelf, I moved some drawers away. This storage rack is cheap and easily fits in a tight area, such as my room... Empty spaces reserved for more drawers and the upcoming 2015 2H sets. I use this table for most of my work: physical building, taking pictures and videos. Now I’m disassembling my tow truck for a new project... Notice the most important thing for me in this pic? Yes, that dictionary... Everything big (wheels, buckets, etc) is in this blue box. And that’s about all I have for now...

As far as I know, you could file a complaint to taobao’s customer service, submit a claim of copyright infringement. Don’t know if it works all the time. I never tried. Just too many of them... One fells, one rises... It makes me feel worse than “sad”...

This is sad. As a Chinese, I feel ashamed of it. But there is nothing I can do to change it. TAOBAO.com is the biggest C2C online shopping site in China, probably across the globe. You can find anything you want to buy on it. Basically anything. So I don’t think any MOC designer would survive as long as he made building instructions and put it online, whether it’s free or for sale. I’m pretty “confident” that my fellow people would do that. I even found my forklift on that site. Just type in the keywords (sometimes in Chinese characters) in the search bar and you will be surprised. We are famous for making products, But mostly low quality products, low tech products, fake products, And completely having no respect for copyrights. Again, Shame. That’s why I don’t use our local LEGO forum (I’m not gonna name it) but focus on Eurobricks. I don’t see creativity there.

Sorry mate, it’s imperfect so I won’t make instructions.

32195 is pretty ancient to me and hard to get

Those two lines have to be equal in length. If the vehicle’s width is determined (it means the red line’s width is determined), try to make some adjustments on the green line to make them equal. Thanks, Sariel. It does need bigger wheels. I did consider the possibility of a gearbox and made a prototype roughly like this: All same functions achieved but with a higher deck height, so I gave it up.

Good catch on those beams, they are not in my original design. I don’t know if the chassis will break without those beam, it seems fragile down that part even with 5x7 frames. You’re right about the rear wheel covers, I made it large only to create a delusion, which makes you think the truck is not so long and the bed is not too high... Front suspension is a total failure to me. Those shock absorbers have a travel distance of about 1 stud, and they are fully loaded...Perhaps I won’t try a truck this size and weight any more...

It’s a simple combination of a 12-teeth gear & a 7M gear rack. Note that the two thin beams highlighted in the picture is a little bit in the way of the wheel hub's movement, but not a big problem. The real problem is, the truck is too heavy and the Servo didn’t work quite well. Such kind of independent suspension should be used on lighter models, or using more wheels for extra support. I still don’t figure out how to solve this problem on a long-wheelbase model without using more wheels. About a good turning circle: more steered wheels. Both on the front and back. Like set 42009. Outwards angle? How? I’m still a newbie to this forum and Technic building. Long way to go. Think I need more better MOCs to earn one.

You’re right. To let the shock absorbers bear the load alone is a terrible thing, just like the front axle...So I used a pendular suspension, two rear axles can “rotate” independently and let the three turntables share the load. Also two Technic Pinballs are added to each axle to reduce the “rotation” like this:

Hi, everyone! It’s been a long time since I posted my last MOC on EB. Today I’m gonna show you one of the projects I’ve been working on lately: a flatbed tow truck / US style wrecker. This is the biggest MOC I’ve made so far...And it is packed with loads of features & functions. Some general specs: Weight: over 4 KG Parts used: over 3800 pcs Dimensions: 760mm (L) x 170mm (W) x 220mm (H) It features: - V8 fake engine - Openable doors - Working headlights - Independent suspensions on front axle - Pendular suspensions with shock absorbers on rear axles Motorized functions: There are 8 motorized fuctions in total, powered by 9 PF motors, remotely controlled by 1 IR Controller + 1 IR Speed Controller (channel switching on both controllers is needed), simple structure with no gear box: - 2 XL for propulsion - 1 Servo for steering - 1 M for opening bonnet - 1 M for wheel lift lowering & raising - 1 M for wheel lift reaching out & retracting - 1 M for bed tilting - 1 L for bed sliding - 1 L for winch A video showing all functions: (Original video on YouTube is 60fps, don’t know why it doesn’t work here) I managed to hide all motors inside the chassis, including the one that powers the winch. I’ll talk about it later. Some more video clips: (Again, all 60fps) This is the propulsion motors assembly. 2 XL hard-coupled with 12-teeth bevel gears, and has a total gear ratio of 25 : 9 before power reaching rear-axle differentials. That’s enough torque to propel this heavy truck. Rear axles have pendular suspensions, connected by 3 small turntables. Soft springs are for balancing. Structure is solid enough to bear the load, but I also designed a similar one with extra support on the middle turntable. It’s 1 stud longer so I didn’t use it on this already long truck. This is what the chassis looks like.I was wearing latex gloves for anti-sweating... Eight 200mm-long PF extension cables were used to connect motors to IR receivers and IR receivers to battery pack. They were well hidden right underneath the battery pack. Now let’s take a look at the bed. In the picture above, the arrows indicate how power goes up the bed. Red ones are for bed sliding while green ones are for the winch. I decided not to put a motor on the bed because it is ugly and too big. A real flatbed’s winch motor is fairly small compared to its size and usually unnoticeable. As a result, I have to compromise on deck height... More photos: At last, I have to say I’m not satisfied with this MOC for several reasons: Deck height: just too high for a flatbed. As I will not compromise on a visible motor on bed, height increased at least 3 studs. Loading angle: about 19 degrees, not a good number Most importantly, too long and too heavy. Front wheels and Servo are working under high pressure, even with 3 hard springs on each side the front part is still overburdened. Perhaps an extra pair of wheels in the middle would solve the problem, but it will lose its aesthetics and no longer looks like a longnose US truck. I didn’t want to publish it at the beginning because it’s imperfect, but I spent too much time on it and don’t want to waste it, so finally created this topic and shared it with you. Again, see my other creations on Rebrickable at: http://rebrickable.com/designer/musenkevin And my YouTube Channel: https://www.youtube.com/c/KevinMoo Enjoy!

Looks great in red, and I think it will look better if the upper part of the cabin is black.

I was planning to make it totally black, but I didn't have that much technic panels in black colour so it came out like this

Hi. New MOC to show you. A LEGO RC quad bike. It features: 4WD with differentials Full independent suspensions Working handlebar Manually controlled headlights / taillights PF L-Motor x 2 for driving, PF Servo Motor for steering It has a compact design. This is the first time I tried to add PF switch & LED lights to a MOC. Honestly these cables are really annoying but finally get it done. More pics: A short video here: Building instructions (photo sequence in PDF format) available for FREE at Rebrickable ENJOY!

This tiny update includes: Bigger file size with sharper images No editable markups (arrows, circles, texts), no embedded fonts - Actually I locked these markups with a password in the old version in case you move them by accident so it's not a big deal, but they'll cause some problems for Mac OS users when they open the file with the "Preview" app. In this new version, every sigle page is a pure "picture", nothing else at all. You can open it with whatever software you like. This BI is still imperfect to me, and I'm still trying to get the hang of the BI-making process. But I think this will be the last update on this project.

Sorry for my incorrect expression, I think you mean "wagon". I need more time on my poor English.

Cute one :)

LDD+MLCad+LPub mainly, also SR 3D Builder+POV Ray+Adobe PS/AI/Acrobat Pro are involved...

I have to make some compromises. :) Glad you like it. Becasue it's not an "Official" set. Right, a real forklift does have a sharper steering. A 12-teeth gear and a 7 studs gear rack will be much better. By the way...PF cables and strings in the BI are really annoying...Get it done, though.

Right, a precise movement depends on the shape of the cams and how you position them on the shaft. But this is the best I can do with standard lego parts while trying to make it as small as a real hand.

Hi. Me again. Another old MOC to share with you. I saw this video of drumming fingers on Youtube: It looks interesting and I decided to make my own LEGO version. This is how it looks like: And a short video: Only 130 parts in total. More at: http://rebrickable.c...rumming-fingers Enjoy it!

Some side holes of the Ls are used as part of the whole structure, which Ms don't have, but you can try anyway. Not sure if it's a rigid structure any more. I do, but never posted anything.
