It's good to hear you like the idea. I attached a print screen of an Excel calculation of the initial force, angle of attack and maximum height travel. As we can see at 2 degree angle, it needs enormous force of at least 70kg to initially move the lift up with 30kg load plus the weight of the platform and to keep upright at only less than a kilogram of force. The maximum travel height of 90cm can be achieved with double scissors with at least 30cm horizontal travel for the cantilever, hydrolic or scissors car jack or an electric gate opener. Whichever you prefer to drive the scissors lift. It make sense to me that some design they rear arm to connect the hydrolic to increase the initial angle of attack means less force you need to initially move the lift. We can look into detail construction later.
