Getu32- 'commercially available' in Saudi Arabia isn't something that most of the Practical Machinist board would be able to verify.
Running an automotive DC winch in an industrial environment with 3-phase AC power really only happens when that DC winch is on some sort of electrically-driven mobile equipment (like an electric shop truck with a little boom crane).
Automotive DC winches are designed for occasional extraction of a vehicle, they don't last long under industrial use, and are NOT designed or rated for any sort of overhead lifting. As you noted, the current draw goes from something 'reasonable' to extremely high, and this variation is in direct proportion to load. To run it off of AC mains, you'll need a power supply very similar in size and operation as a MIG welding power supply, with voltage turned down most of the way (they usually START at 16-17vdc, and go up to 34ish)
