Re: Scissor Lifter?

We built one in our rookie year (1996), we never even thought to replicate that experience since. I use a scissor type man lift here at work on a regular basis. In order for it to work well, a rigid precision frame and bearings in the joints are essential. The problem with most is the non-precision with which they are built. This leads to instability while moving and therefore intermittent loads that exceed the ability of the drive to overcome.
We have a do not use list too...
No casters/shopping cart wheels for obvious reasons.
No omni wheels on ramps.
Anything else that does not fit the game.
