Vevor 3 Ton electric scissors jack emergency manual cranking ratio

should you ever entertain the idea of using the manual crank handle to jack up the car- 🤣
This should give you an idea of what you're in for.
if you thought the rate that the jack works is slow going, this would be the rate you'd have to spin it just to achieve that speed.
While it's within the realm of possibility, using the hand crank handle is best relegated to periods of extreme desperation with no other options.

By the way, don't try this for more than a really brief instant because the plastic of the handle and housing will melt from the friction.
