Bye to all,
I have to design a column for car lifting with 2 rotating arms (90 degrees each). the lifting method can be hydraulic (cylinder-pistone) or mechanical (violet-chip). which is the best road? Is there anyone who can give me useful advice on this?
thanks in advance

I remind you that the presentation is welcome, and that it is highly recommended to read the general regulations and this subforum.
As far as your problem is concerned, you should put a maximum pattern of what you want to achieve, so that you can think better around.
Bye.

How do you lift a car with two rotating arms of 90°??? make a pattern because you don't understand.
I think you have to make a bridge to lift cars, which have two columns and on each column 2 adjustable arms in extension and angle to fit the lifting points.
then there are two screws on the columns or rack to lift the car.
car lifts made with hydraulic cylinders are no longer in law, therefore abolished and prohibited.

if you have to do pantograph lift I'd say it takes the hydraulic cylinder.

but are already standardized and standardized solutions.
