Surprisingly, an electric wheelchair can manage this ramp if the person in the wheelchair is able to lean forward slightly. If not, it will tip over and the small stabilizing wheels at the back won't be enough. I tried my dad's electric wheelchair into an even bigger incline out of curiosity and the torque is amazing. It is still incredibly dangerous tho. If there was some kind of cable that prevented the wheelchair from tipping backwards, this would be acceptable.
A winch set at the top of the slope, with a cable you can attach to your wheelchair, and a button on either side of the slope that you can press to call the cable to yourself or have it pull you up/lower you down. Could work, would probably be pretty scary to get lowered down backwards though.

No, the electric wheelchair can handle the incline, you just need a stabilizing cable. Also, this is completely unusable when it isn't completely dry.
Electric motor can have unbelievable torque delivered as quickly as the power supply can allow.
