Adding an outlet would be my first choice.
I would next suggest checking to see if the motor is 110 v capable. It may just require moving some wires or jumpers. You would also have to check if the control electronics need to be modified.
Alternatively, assuming your lift is in the 3-5 hp range, just get a 5000W or so step up transformer. They are less than $200. This is probably the safest and fastest option other than a deficated circuit with the proper voltage, assuming you have the current capacity.
