Vertical Lift Emergency

Are team is having a big problem with are arm. Are advisor ordered us new parts but made a mistake in not ordering linear slide kits.

Are team wants to make are mechanism go up and down vertically.

We crossed out scissor lift although its and idea we don’t have room.

Please could you give us ideas for lifting a mechanism vertically without linear slider rails?

I was thinking of using this idea for lifting but is wondering if the slide rail is extending? If it is getting longer then i can;t use it? What do you think? - YouTube

Thank you guys so much i am sorry for any trouble!

But yes keep the ideas coming mahalo!

Vertical Tank Treads with your arm attached to a couple of links?

Sure - There is more than one method already posted in the public Gallery.

Here is are pictures of what I and my students did in the days before the slider and before the heavy chain.

We strapped tank tread to C-Channel and then wrapped a motorized tank sprocket around the C-Channel and tread. It works fine. If you have more than one of them attempting to work in together you have to worry a little about keeping them at the same height (so that whatever they are lifting stays level/unkinked).

You can also use chain or tread like ropes and lift a platform up to where a motor or pulley (that is already high enough) is mounted. These pictures shows a combination of both ideas.

Thank you guys so much! I have posted a link in my first post could I use that idea or i cannot? The reason is that it is moving vertical, but my concern are the slide rails. I am not sure but are the slide rails moving?

Any more ideas?
Don’t be scared my team is willing to take any workable vertical lift system!

Keep the ideas coming. I am liking the ones so far.

The video you posted uses slide rails, and yes they are moving, that’s how it raises and lowers the bar. So you will not be able to use this, as you do not have any slide rails. I would suggest trying Mr. Blake’s idea.

FYI - The methods I used in those pictures can be adapted to using the Advanced Gear Kit’s rack gears, if you have them.

PS: The best way to find out if something will work is to do the math/design on paper (or CAD), and then trying promising ideas with the real equipment.

The second best way is to try them with the real equipment before doing the paper design.

The third best way is to rely on other folks to give you better answers than you can develop yourself. :wink:

You already have everything you need for the two best approaches :slight_smile: - Have fun experimenting and post a picture if you develop a solution you like.

you could use this

Thank You so much! I surely will tell you and post are design when we finish. Now its time to test and get ready for are first round up competiiton august 18 !
