Nice tests, didn't expect it to be able to lift so much! With the scissor/parallelogram design you'll also have to consider the starting height: the lever of the mechanism is the vertical distance between actuator/string and joint, which obviously increases the higher it gets. So, the extended form of a scissor can lift up to 5x more than the retrachted one.

Thanks for the comment! I was aware of the lever but i wanted to see how much it could lift from its fully ‘closed’ state. Balance was difficult on this one - unlike lifting a car with a scissor jack where the car has other points of contact with the ground to keep it stable, the unrestrained weights slid everywhere!

These designs are incredible! You're a real engineer. Seems to me the weak point is always going to be the gears in the end, because the plastic teeth fail very easily under heavy load.

You can add more in parallel but after that the axles become the weakest point and it will twist itself apart.

You need to do a part 2 because as someone that has done this before, you can lift much heavier than what you did AND with less parts. Utilize more gear racks and gear Turntables in your build. Multiple Turntables handles distribution load much better than single axels.

@screentimer

27 күн бұрын

do it then

So one of the best lift tables you can buy for machine shops and whatnot has 4 long verticle threaded shafts in the corners and what is effectively a large nut attached to the moving surface of the table. For low torque applied to the threaded shafts, you can lift massive amounts of weight on the table. You could easily replicate this with a long lego axle and worm gears lined up on it, attach some gear reduction to the bottom of each axle, then chain it all to one motor. With a proper table design, which shouldn't be that difficult, you could have lifted significantly more weight than a normal rack and pinion setup like this video used.

I love to see how the failure point changes from improvement to improvement

5:00 this actually turned into a pretty cool looking dystopian city or industry plant type building lol

Cool experiment! The best power/holding would probably be with worm gears driving gear racks on the lifting platform, as these have more "teeth" in contact with the weight carrying portion of the device at any one time.

What's funny is that he used the scissor jack design, when that's usually paired with a bolt tightening mechanism, not dissimilar in principle to a worm gear.

good video. just had to say tho, as someone who spends a lot of time figuring out how to optimize the strength of drivetrains and suspension systems for the insane forces they can see during extreme operation, some of these connections and joints hurt my whole brain

Quick answer: as much as you want as long as you have proper gear ratio. And we are not even touching hydraulics yet.

That is a cool scissor lift :)

It would be cool if you compared the mass of the lifts themselves versus how much they can lift

Arrrrghh… this is torture. Torturing the bricks and the engineer within me. Repeatedly fixing the symptoms, but never treating the underlying problems that caused them in first place. And those poor gears! They did not deserve this! 😭 Very cool video, but it kinda grinds my gears. Pun intended.

Im really impressed i didn't thought lego could lift so much. Awesome engineering and design 👍 could you do a maybe a yt short where you try the last Design just doubled? So 4 motors and 4 sets of gears and a higher gear ratio. If the fragile plastic is the problem then the solution might be distribute the weight on even more gears? I got really curious and was already anticipating a bit that you would push the limits even more after i was surprised that often :D you might remember as well another youtuber (i forgot the name) who used gears and axles made of some kind of metal that would help a lot but it wont be legos but im sure it could also lift even up to 50kg with your clever engineering

3:30 Now this one's a beast!

I don't know if you will see this, or if it will be relevant or not, but a few years ago I watched a guy lift a concrete road barrier using only Lego by building one hell of a block and tackle crane set up. It needed a few metal axels and by the end most of the supports that the axels spun in were destroyed, but he did manage to lift it an inch or so off the ground.

It's also a question of how much lift height you want, a lever system could of course lift a huge amount without putting stress on gears and stuff but only travel a short distance in height.

For the Brits. That 2 whole buckets of tooth plaque.

When I saw the thumbnail, I thought it was gonna be able to lift a car for some reason, honestly I’m surprised it doesn’t Legos are pretty strong

what about trying the last design with worm gears instead of gears?

I'm no engineer of sort but I've seen some major flaws in the pulley system, ofc it failed splitting the gears which is what I didn't notice at first. That thing is bending, and the torque needed to start the pull is higher than from 50% on. It all spreads trough the structure, and imo it gonna crack it after splitting the gearbox at 2:00 and before consuming the wire against brick's corners. You apparently need a stronger chassis, its kinda disappointing that the main point of failure there are bricks connection and not power or simply the ABS the material itself. I enjoy all these experiments video tho! :)

You should take all of your broken gears, and melt them down into either other new Lego parts or sell them as some kind of merch (Lego-engineering themed trinkets and such)!

whats the weight in freedom

Now I'm wondering if gearing down + worm gear and rack would reduce some of the gear slippage 🤔 need to go buy me a load of technic to find out 😂

You should do the weights in different units of measurement so it's easier for some of us to have an idea of the actual weight.

This damn lego probably stronger than me

Bre make some direct drive worm gear thing.. geared tf down

What about worm gears to lift the heavy weight?

Now think of how much it could lift if you rigged up four of the final version into one thing.

Why did I imagine you creating a Bench pressing robot xd

When i see little machines like this struggle to lift weight that is cake for nearly any human over the age of 7, i am immediately more impressed with our anatomy and how a similar sized body part (arm) can lift 10x the weight

@earlgrey2130

Ай бұрын

Yeah try lifting 35kgs at 7.. good luck with that

The lego every month before gains: “Can you spot me?”

So, theoretically, Lego (or any Technic system) could lift insane amounts of weight, if the mechanism is durable and geared down enough, in practice it'll take way more patience than anyone would ever have to build such a thing

"it is just a small upgrade" *the upgrade:*

It would be easier to get a better grasp on its maximum capacity if you put it on a scale, and above it you have something really heavy that it definitely cant move. Then crank it until it wont go any further and subtract the starting number on the scale, thats it's maximum capacity

I wish this video just kept going

Maybe one day we will see lego lifting car. 😛

Needs XL motors and at least 4x gears per stage to spread the load, not 2x.

If you just gear it down low enough, you can lift any amount of weight you want it just takes more time to do so

@kingofherdaz7860

Unless the materials break. Newton's laws-action reaction. If the force required to lift the load (greater than the mass times gravity) is greater than the yield strength of the material (ABS in the case of LEGO) then the material (axles and/or gears) will deform rather than lift the load.

I somehow expected it to lift 40kg judging from the thumbnail 😅

When you run out of weights and start adding random stuff 😆

Everyday we get closer to legos phasing out other technology

78lbs, that's nuts

Not the point of the video but, can someone tell me the name of that dumbell? Brand or whatever.

I feel like the tests done with the scissor jack are not completely accurate since you were putting force on it with your hand. For a clean controlled data it would have to be unchanged by external factors.

45 minutes later... Toyota Corolla enters the chat... 😂

try it with metal gears

Can it blend?

My record was 65 kg but it can be much higher dont slow down your motors do everything with the cable

so it comes down to the strenght of the parts and not the power essentialy... =)

If you create a (+) shape, you might have more power and more stability. Even 45 kg could be lifted.

what about snake gear lift??

You people build amazing things but sometimes engineering is still a challenge.

The maximum lifting weight depends only on your budget and engineering skills.

Just a question from a person who stumbled across your channel: are you a mechanical engineer by trade?

What's that, like 6 AA batteries and less than a kilo of Legos lifting a 9 year old? That's actually mind bending to think a kid could stand on that last one and it would support his weight at all without collapsing, much less be able proactively lift him up.

How much weight is this in freedom units? 🇺🇸

It could almost lift me, if it could do another 10kg that is lol

When gears are cracking its not a pass 😜

1:00 1.7 Kg? Looks a lot more like 3.75 lbs. Why state weights in units other than what the weights are labeled in?

all u needed was more triangles, u had the gear reductions already

that's quite some engineering, are you an engineer by trade or is this just learned from experimenting with builds?

Scissor lifts are not the most efficient at lifting high loads to begin with, especially when starting out flat
