    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.

    • @BuilditwithBricks
      @BuilditwithBricks  10 місяців тому +45

      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!

    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.

    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.

    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.

    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! :)

    The second design has a cardinal flaw making it less effective than it is. You spun the gears the wrong way causing the strings to bend over the frame at almost 90°. Due to the tension they are under it will cause a lot of friction resulting in loss of lifting capabilty.

      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.

    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
