imajor Posted April 30, 2013 Posted April 30, 2013 Hi, I was originally building Nico's forklift (which I really like), but since it is an 5 years old design, it is not utilizing some of the recenty released new parts. So I decided to try and change it, mainly to use a servo for steering. I finally ended up creating a new body, only kept the fork. I know the result is not great, but I thought I post it here, since it wasn't easy for me to do this. It is using a servo for steering, L motor for propulstion, and two M motors to operate the fork.

N-4K0 Posted April 30, 2013 Posted April 30, 2013 Not really a big fan of forklifts, but this looks cool. Quote
Lakop Posted April 30, 2013 Posted April 30, 2013 I like that very much. I'm interested in the mechanism to lift. I know of a lego forklift that used string (set 8416) but I'd like to build something, that could lift a decent weight, without using string. I also came across a lego forklift that used the small chain links. It had a special part. H Quote

I also came across a lego forklift that used the small chain links. It had a special part. H I agree with you completely, using chains instead of string would look much better. I was trying to do that, but I could not come up with a nice solution to stict the last element of the chain to the fork/body. There is a set which used the small chain, see here how it fixed the chain to the fork. Another problem with the chain is that I think it is not as strong as the string, even if it was used double on the two sides. But still if anyone has a nice idea how to do the fork with the small chain, I would appreciate that. Thanks for the comments. Quote
Lipko Posted May 1, 2013 Posted May 1, 2013 (edited) How about this part? (Technic Chain Thread) I just started to build a forklift. I'm still not sure to use chain or string. String is not only stronger but it's easier to attach and route. Chains are not applicable to 8 teeth gears and 16 teeth gears are a bit big. Multi-section lifts can get huge real fast.

Splat Posted May 1, 2013 Posted May 1, 2013 Nice forklift It looks like it has good maneuverability and can lift quite high. 8843 set uses chains to lift the forks, and uses the Technic chain tread that Lipko mentioned to connect the chain to the forks. More info at Technicopedia: http://www.technicopedia.com/8843.html 8835 and 8872 also used chains, but not in a telescoping motion like 8843 did. Quote
Someonenamedjon Posted May 2, 2013 Posted May 2, 2013 Modernization! Great work though, but is the forklift really that slow? Quote

Yes, that is the part which is used in some official forklift sets, to attach the chain to the fork/body. I don't have this part, but it doesn't seems to be a trivial thing to fix the fork to this element. What is the size of those holes? I guess it is not big enough for a regular pin, is it? Modernization! Great work though, but is the forklift really that slow? Yes, it is that slow. It is easy to change the gearing and make it faster, but I wanted it to be strong enough to go across a few small objects, and climb up some small slope without the gears start to slip. Quote
Gene Posted May 2, 2013 Posted May 2, 2013 I believe most forklift operates very fast with a sharp turning radius. Since this is Lego, I'm already impress with video shown here. Just checking if anyone knows 8416 has the build for motorization? Quote

Just checking if anyone knows 8416 has the build for motorization? I didn't know that. But if this would have been faster, I think I couldn't record this movie. There are situations, where it should move just a little bit forward/backward, where low speed is needed. I tried a faster setting with a IR speed remote (for steering also), but it wasn't comfortable to operate the vehicle. Quote

I tried a faster setting with a IR speed remote (for steering also), but it wasn't comfortable to operate the vehicle. What about a simple two speed gearbox,that could also control the mast pitch? Something like that would not require another IR receiver. Quote
Splat Posted May 2, 2013 Posted May 2, 2013 What is the size of those holes? I guess it is not big enough for a regular pin, is it? There are 5 little holes in these tread pieces. The holes are too small to insert a pin into, but are the correct size to insert a 'bar' (such as a light-saber piece or similar), although I can't remember if there is much 'clutch' with these holes. The holes are also the correct size for the little 'posts' that you find under a 1x6 plate, so these can be attached to the tread piece quite easily. Quote
