Full Length Car Ramps

So the past few days I’ve been thinking of a way to be able to work under my cars easier until I can someday install a lift. Well, I think I may have found the solution. I’m thinking about making something similar to this but with a few changes.

A few changes I would make is to make the whole thing longer. Like maybe have the horizontal part 14’ instead of 12’ and make the approach ramps 10-12’ instead of 8’ to offer a more gradual slope. I would also add tabs that would allow me to pin the sections together for more peace of mind/safety. Another idea is make the section between the front and rear wheels where they could be removed once the car is in place to make it easier to work in those areas, however, at 20” tall, a creeper would easily fit under the side sections if they were built like these. I would probably add some diagonal bracing in the sections under the wheels though.

Here’s the entire blog with all the details how he built them.

Have any of y’all built anything similar to this? I’m open to ideas/suggestions
