Like Eric said, you don't have enough torque to move your lift. Electric motors have a "start-up current" that is higher than the normal current it draws. Since your motor is under such a high load it cannot electrically overcome the initial resistance. When you move it,physically you are physically providing the force the motor needs to startup.
one wrong move and you could end up capping one of the judges. that will pretty much ruin your chance at judges' award - Mike Ciance [more]
