It is a car lift with 2-columns like the mechanics use in in the garages.
Actually it is very simple. The lift mechanism is a worm and rack. It is very compact, strong and reliable.
It includes arms with adjustable angle, and rubber in the end to prevent the car will slide out of the lift and crash to the floor.
It also has auto-stop function,, in the top and in the bottom.
Powered my PF XL motor and a PF switch.
