Cable telescopic frame

- Turn the pink pulley to make the violet frame go up and down.
Each of the red and blue cables has one end fixed to the pink pulley, the other to the violet frame. The green pulleys are identical. The weight of the moving parts ensures the cable tension.
The verticality of some cable branches is not compulsory.
In case of horizontal arrangement it is possible to add a second similar cable system for return motion.

It is pure joy to view your videos, dear Mr. Thang!
If the crank is turned down too fast, the parts, which have been raised, will go down at the same time and the cables will be slack.
If the crank is turned down slowly, the parts, which have been raised, will go down at the same time and the cables remain strained but less than before.
Why not use rack and pinion
outstanding work mate. so clear and easy to understand.
You are the best. Very easy to understand, outstanding work!
The violet part always goes up first, then the yellow and lastly the blue.
ロック機構ありがとうございます。
just found your video. am building a drywall hoist. i have seen the work but never quite understood them. this explained a lot. thanks
Thank you. Your comment encourages me a lot.
Fantastic M.advantage 🥰
During going up period, if the crank is left, all parts, which have been raised, will go down at the same time to reach their lowest positions. To keep the system at halfway it must be equipped with an automatic brake like in case of hoists.
Genius! Thanks for sharing.
Excelent video. Thx
And if you reverse direction and start turning the crank up again, will they raise on the same order or will they raise all at the same time?
In this example it looks like it only goes down from gravity, but if you ran a cable up the middle through a hole and it connected to the top piece would it pull it down correctly? Thanks for the video! 😃
I am not sure.
In this video one end of the cable (in blue or red) is fixed to the pink pulley.
Same questiono... What if i need it to work upside down sometimes
@@CarteiraRica-oficial i 3d printed one and yes it does work at least on a small scale, but honestly a chain driven one is better. like this one: th-cam.com/video/yGxCs2ka7HQ/w-d-xo.html in the chain driven system, each section is moved at the same speed relative to the previous section, so it's more stable and consistent.
hi great animations! what software did you use please?
It's Autodesk Inventor.
While technically possible, I just wanna point out that the torque required to do this wouldn't be worth the end result.
Still neat, though.
Rather than a hand crank, you would drive it with a reduced gear.
What would happen if you let it go down halfway, then crank it up again?
What if instead of let go, you just crank it down half-way?
👍🏼👍🏼👍🏼
чем выше поднимается , тем меньше усилие
What is this software you used in the simulation?
All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.
can i have the inv file for this?
Link to download Inventor files of this video has been added to the video description.
I want to use your mecanism for a table. Can I make the violet frame thicker and it will still work it?
My video can show the working principle of a mechanism only.
It is necessary to redesign it to meet your conditions based on calculations and experiments.
