- Blue slider can be positioned at various positions during going up thanks to yellow lever of pink pin and the gravity.
Red spring forces the pin towards the teeth of white runway. Small slot on the yellow lever prevents the pin from contact with the runway teeth once the spring enters the slot.
Slanting portions at the ends of long slot of the runway control the meshing of the spring and the slot of yellow lever.
At highest position of the blue slider, the pin is separated from the runway teeth. The pin does not contact the runway teeth when going down.
At lowest position of the blue slider, the spring is pushed out of the lever slot and the pin now can contact the runway teeth.
So the engagement of the pin with the runway teeth is controlled automatically.
To get higher position of the blue slider: raise it until it locates into desired holding position.
To get lower position of the blue slider: move it as high as possible, then move it down as low as possible and raise it until it locates into desired holding position.
This mechanism can be used in

Trying to figure out how to use something like this in my Mark Rober class. I think this is key to what I'm trying to do. Thanks for putting this together for inspiration.
Brilliant, this is the kind of video that gives thousands of dollars worth of value to the world.
Great. If I had the time I'd love to build these mechanisms just for the hell of it.
Perfect. You are best teacher for our.
Love your work!
Imagine what you can do with it many ideas . Thanks for sharing love
Awesome idea..thanks for sharing it
thanks for sharing, great design
thanks broooooooooooooooooooooooooo.. its a commentable mechanism..great work
Beautifuly done!
Perfect thanks for sharing this video
Thanks for sharing.
Ah! So that's how those things work!
Congratulations !!
Nice!
Fantastic! Thank you so much for your work - this video is very interesting and useful! Greetings and best wishes from Ukraine! Konstantin.
Greetings from Vietnam!
hay quá bác ạ
Very clever.
Yes indeed
Very nice
I love this. Thank you for post. What can be done to mitigate wear of the red spring? The way it gets reset at 0:38 seems harsh. Do you have another similar variant to this but with different self reset upon returning to origin?
Sorry, I don't have another variant yet.
You can break the cam into two and add a spring to the lock which engages with the red spring. You can mitigate wear with this. Although at the cost of slight complication.
nice!
Sir, how do you think and design all these intuitive and new mechanisms? Awesome work as always.
A difficult question.
Maybe because I work a lot and new ideas come by chance.
I've been very curious, does a sprag clutch offer the same benefits of a ratchet bearing?
Yes. Please compare:

Hi, I really like this mechanism. Do you have a reference book or something to size it ?
Sorry, I don't have.
谢谢你带来这么多的动画视频，请问你是用什么软件设计的？
It's Autodesk Inventor.
Why did the yellow thing does not get into the slot back, when it goes down
It's because of the red flat spring.
It hooks into the slot of the yellow lever and prevents the pink pin from contact with the runway teeth.
Doesnt the yellow part need a torsion spring?
No. The red plate spring is enough to control the yellow part.
Hi sir , you are you tube chenal so masking rewinding machine in the turret inside mechanism assembly to keep Guide line. Please sir
I don't understand your request.
A picture or video may help me.
Boss can you make a video for Excavator telephonic system
Show me a picture of the Excavator telephonic system.
I don't know what it is.

This system brother
Thank you. I will study it and make its animation if possible.
Ohhhh.... shittttttt.
