Is Anyone Using Motors to Hoist themselves off the platform on the bar?

[xxlshortys]

I was wondering if anyone was using motors to hoist themselves up off the platform onto the bar, and what kind of motor they were using. We tried ours yesterday without success, and were trying to be efficient with the time we have left to solve the problem.

If anyone has any suggestions let us know, i believe pneumatics are out of the question because we are using them in another system. (but that could always change)
