Shaft with a estable base

[Gustavo Silvano]

Hello there!

My name is Gustavo and I'm from Brazil, I'm currently working on a steelmill and here I do some projects. Now I'm working on a project where one solution for the problem is to use some kind of inverted pendulum where the base at the top system needs to be estable during the movement of the pendulum.

I'll use this to move a load from one point to the other without using a chain system.

Attached I have an illustration of what I want to do. So the system consist bascially on a shaft with three arms, and at the end of each arm I have a base where the load will be held. The problem is how I keep this base estable, in a way that the load will not fall from it. Do any have a solution for this? It will great if the solution is cheap to be implemented.

Thanks!

Two parallel shafts instead of one would ensure the table stays level... that would depend upon shaft movement only, not gravity or an electronic control like with a single-axis/-arm system.

Goggle "four-bar linkage"

MacGyverS2000, will it be something like the attached file? Can you explain me better how this wil ensure that the base will be estable during the movement?

Jboggs, how can I apply the four-bar linkage? Because my system only have a single fixation point, and the four bar linkage have 2 faixation point.

If you can support the base then this slot drive may work.
