I am considering buying or building a set of ramps similar to the first set on the page (w-w-w.carrampstore.com/. My only concern is where I use them. A concrete slab is unavailable and I plan to use them on a compacted dirt surface. I expect it to sink in to some degree, but I’m not sure how much. Would there be any issue with sinking in?
I was thinking about using quickrete and pouring small slabs under each support on the ramps, or burying solid concrete blocks under each support. Which one do you think would be better? I have to level out the land before I bring in any ramps, so either way would be easy enough to do.
I have a short set of ramps from Harbor Freight that seem to work fine, even in the dirt. I just want something longer to make exhaust work easier. I assume that the long set wouldn’t sink in any more than the short ones, but by the time I have an 6000 pound truck on versus just the front or rear wheels on the short set, will it still be OK? The largest thing I plan to put on it will be a 99 Suburban, but that may change later. Definitely nothing more than 3 tons.
Thanks in advance!
P.S. I always use jackstands under the vehicle, even when on the ramps and the wheels will be chocked. If I have to have the wheels off, I use two jackstands for each wheel removed and I leave the jack propped up under the truck as well as the wheels are placed under the frame.
