Flip up garage door 2 

Thank you for the information.

Cảm ơn cháu về những lời tốt đẹp.

Cho hỏi sao phải dùng đối trọng cho nó kềnh càng nhỉ.

Your invention is great: simple and effective. I love it and its author 😊.

@@thang010146 Thanks for the good feedback) And good luck with your work! If you wish, go to my channel, besides the lifting gates, there are many more of my works. My hobby is boat building and everything related to them. I made a manual crane for lifting the kayak out of the water using blocks. A working model of a one-handed commander was made to control the throttle / reverse of the outboard motor. I came up with the design myself. The last work is a nesting three-section kayak N3SK.

@@thang010146 And here is my first model of the gate Z-system ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_eDH4HyT-18.html

Thank you for showing me your channel and the first model of the gate. They are very useful for me.

I think one motor is OK.

Glad you like it!

Firstly, I build all the parts with dimensions that seem to be suitable. After assembling them in the software, "Try and adjust" is the way I use to get the desired mechanism.

@@thang010146 Thank you very much for the explanation and sorry for the very late reply!

If you are interested in the construction of the Z-system gate, please contact me. I am the inventor of this system and Mr. Thang has a link in the description for my video. My site Z-system.pp.ua 👍

You can use this design for your door. I have no information about the hardware.

Sorry, I don't have it.

I just create animations of machine mechanisms. If you know a mechanism regarding Laplace Fourier things, please show me. I will try to animate it.

Please use CAD files of the video. Links to download them are in the video description.

Probably. I only ever use counterweights to make things easier for another source of power, like a cylinder or a human operator.

Yes, manually. The counterweights aim to reduce the operating forces.

All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.

@@thang010146 can you show something in doing or making videos

Заходите на мой сайт Z-system.pp.ua, эта модель сделана по моему видео, но ворота сделаны немного не так...

Yes. Please make the frame a bit higher to get some gap.

@@thang010146 thanks for interest
