It sounds to me like you have no software developed to avoid stall conditions like this. In the future, I'd recommend installing sensors so that your motors don't cause harm to your machine. Limit switches, reed switches, and Hall effect sensors are popular choices.

Also, you should be able to use the new RoboRIO to gather current draw data from the motors and to shut them down if they exceed a certain value in case your elevator is getting caught on something else.
