Hi,
We get so many questions about creating scissor lifts, I thought I would create an example for everyone. I'll come back and spice this up with more "how-to" info later, but for now you can download the models and try it out for yourself.
The latest version now includes some cool servo motors from Todd Kraft!

A couple of interesting videos regarding scissor lifts. I am sure there are others out there...
