I have used the car ramps in the link below for just over a year and have since changed / improved the design.
http://www.mig-welding.co.uk/forum/threads/laser-cut-car-ramps.50392/
The ability to lift the car ramps hasn’t really been used that much, instead I made the end platforms a fixed height which makes them a lot stronger and they are 100mm longer so there 600mm long x 300mm wide 270mm high which helps if you need to jack up the back of the car as well, as the front wheels can move, the ramps are still 950mm long. Also all the corners of the cuts are now radiused, and an extension ladder can also be bolted to the ramps (not yet made), and there hot dip galvanised hopefully won’t start rusting to quickly.
The ramps are made from 3mm plate with 20 x 20 x 3mm angle, the ladder extension part has another 3mm doubler welded to the outside.
I don’t claim to be a professional welder, just a DIYer but how they can still sell the blue car ramps pictured I don’t know, can’t say I have used them for at least 8 years.
