Cable telescopic sliders 1a

Input: motor pulley (in violet).
There are two cables, red and blue.
The red cable is wrapped around the green idle pulley of the base runway.
One end of the red cable is fixed to the violet pulley.
The other end of the red cable is fixed to lower pin of the yellow slider.
The blue cable is wrapped around the green idle pulley of the yellow slider.
One end of the blue cable is fixed to lower pin of the base runway.
The other end of the blue cable is fixed to lower pin of the blue slider.
The motor pulls the sliders up. The device to keep the sliders at up positions is not shown. The sliders move down thanks to the gravity.
The blue slider moves twice as fast as the yellow slider.

Thank you very much for many of your interesting informative animations. They awake the curiosity of my childhood that gradually slept as I grew up.

[@CurtisDrew1]

I am about to modify my wall hugger recliners slides so that they will slide out another 4 inches away from the wall. These recliners really need to be placed about 3 inches away from the wall to prevent them from striking the wall. Duh! This cable set up, like you have here, in double action (push/ pull) will accomplish this horizontal tracking nicely. Thanks! This will explain what I envision to my wife quite nicely.

This is probably one of my favourite Mechanisms. It was used in a LEGO set as a Extending Crain Boom.

[@swiftzer3753]

Hey thats right i just realised my 42009 crane uses this!

[@Klingonbr]

Mecanismo muito interessante, graficamente muito bem explicado. Obrigado.

[@Dkm337]

just the genius(ness) of this mechanism is so cool.

Excelente animación muy comprensible

[@FilterYT]

Beautifully done, thank you!

[@thereasoner9454]

If you replace the lower pin on the yellow slider with a pulley, then run the red wire around the new lower yellow pulley, then over the upper yellow pulley, and back down to the blue pin, one cable would work, but you might lose some travel length of the yellow slider.

[@thang010146]

The one cable embodiment can work. When the motor winds in, the blue slider moves first. In the highest position (relative to the yellow slider), it starts making the yellow slider go up through a pin. When the motor releases the cable, both the blue and yellow sliders go down at the same time.

I am from Madrid-Spain, I am confined by coronavirus and I have discovered your videos that are wonderful and I love it. I wanted to know that you use software? Thank you very much for your videos.

All videos in this channel are made in Autodesk Inventor. I wish you be fine.

[@juanorozcofernandez3298]

Sr tang0 en verdad es un verdadero maestro

[@soscilogical1904]

that's wonderful, I wonder if the cable length can be almost constant for the second stage.

[@thang010146]

The length of the blue cable must be constant. The blue slider moves twice as fast as the yellow slider.

[@kirtipandya9353]

Dear friend, excellent as usual

[@k_whitworth]

Thanks for sharing this! Subscribed!! Do you have a recommendation for increasing strength in the telescoping sections if the lift is carrying an offset load, perpendicular to the design footprint shown here?

[@thang010146]

I think the section of the sliders in this video is best suited to take the bending load on them.

[@k_whitworth]

@thang010146 thank you so much. I appreciate your insight!

[@researchandbuild1751]

I think some extendable ham radio antennas use this same concept

[@sottonk]

Been trying to find something similar to this, the telescoping draw sliders that have movement very similar to this but they use ball bearings not pulleys. Any ideas?

Any link for telescopic drive thru chain

[@Ilushaaaaaa]

Are there two cords required ? Or you can use only one cord tied to the electric motor and the other end is tied to the pin

[@thang010146]

Two wires are required.

[@Ilushaaaaaa]

@@thang010146 Thanks for the clarification

[@Ilushaaaaaa]

@@thang010146 will one wire not work?

[@thang010146]

@@Ilushaaaaaa The red wire pulls the yellow slider. The blue wire pulls the blue slider. If there is only the red wire, the yellow slider can move, the blue slider can not. If there is only the blue wire, both sliders can not move.

Great video 👍

[@fernandoebenezer7551]

Can you make the assembley steps per part of your lifter in that video??

[@thang010146]

Sorry, I can not. Please use CAD files of this video to do it yourself. Links yo download the CAD files are in the video description.

[@arturst1146]

Отлично, вы молодец!

[@matthewcarullo5851]

Is it possible to modify this mechanism so that the blue/yellow members cannot be lifted by hand? (i.e. re-arrange so that tension in the ropes prevent this from happening)

[@thang010146]

Does the following design meet your requirements? kzbin.info/www/bejne/baPKh6Bmq66Aq7s

Nice method

[@aravindmpillai8320]

Here the tension on the cables are not exactly vertical. Wont that create a hinderance in the movement of sliders?

[@thang010146]

The fact that the cables branches are not parallel to each other may cause the differences of the slider speeds.

[@ROBK636]

Like the hand crank appliance forklifts?

Hello sir, it is fantastic model. i just want to ask, can i have this?

[@thang010146]

Sorry, I cannot help you. I just made its animation.

[@dogwalker666]

This is very similar to how a fork lift truck works only with a hydraulic ram instead of a motor.

Which software is used for this type of animation

[@thang010146]

[@penamapena]

hello sir, i wanna ask you something, when sliders already lift, did the motor can hold the cable or we need other mechanism? thanks

[@thang010146]

A motor brake (or anti-reversing ratchet mechanism) is needed. If the transmission from the motor to the violet pulley is a self-locking one (for example a worm reducer), no need.

[@penamapena]

@@thang010146 hoo.. Oke sir, thanks

[@atorrance]

Can you a video with a “continuous” style rigging as opposed to the “cascade” style in this video. The differences between these are highly important concepts for students robotics competitions and your clean animations could be useful.

[@thang010146]

I don't quite understand your request. Could you show pictures or videos of “continuous” style riggings?
