About: Hey! I'm Sandroknexmaster. I like building with knex, especially ball machines. I live in Belgium. I speak Dutch, but also English and French. I hope you like my stuff, and like always comment, rate &...

Hello everyone!

The Floor Double Arm Lift is the first of 2 lifts first seen in my ball machine Revolution.

This one is a double arm lift. Nothing special you'd say. But...

It's a bit different than a standard arm lift because the balls enter directly from the floor, not from an entrance track (as the title says).

When it's not in a ball machine, I think the Floor Double Arm Lift looks quite ugly. But it looks better when you build a ball machine around it.

If you're going to build this lift, please read the image notes, they might come in handy!

You can always send me a question if necessary with a comment or PM.

I hope you like it and thanks for watching / building!

    Is there any way to extend the white floor on all four sides without moving the structure holding the arm?

    Yes, then the structure would just come out of the floor and the balls could roll around it. Another thing you can do is make the structure wider, and the axle longer. I wouldn't make it too wide though because then the axle won't be strong enough anymore.

    No not really, the smallest ball machine you can find on my profile is revolution. Maybe I'll make a smaller ball machine in the future.

    Cool lift! Would it also work when I'd only use the arms and motor and build it in a different environment (I was planning to let the arms pick the balls up at the end of a tube-track).
